->''"I have eight other senses; but I'd give them all up, even smision, just to experience taste."''
-->-- '''Bender''', ''WesternAnimation/{{Futurama}}''

One way to make an alien creature seem bizarre to human audiences is to have it detect the world around it with a different array of biological senses than us. Often they're depicted as using sensory mechanisms found in other Earth species, such as echolocation, thermographic vision, or sensitivity to electrical impulses or vibrations. More rarely, writers will equip aliens with biological versions of radar or other technological sensors, or they'll invent senses that discern esoteric forces such as psychic energy.

Senses that are found in we humans are often absent or much-reduced in beings equipped with bizarre alien senses. On film, this trope may be depicted with PointOfView shots using image-distorting or false-color effects. Most commonly seen in ScienceFiction, but occasionally in other SpeculativeFiction genres.

A subtrope of BizarreAlienBiology, and supertrope to MysteriousAnimalSenses. Frequently correlated with EyelessFace. Contrast BlindfoldedVision, in which someone denied their normal eyesight relies on other sensory modes, or SuperSenses, when normal human senses are enhanced. Commonly found in TheMorlocks as well as aliens. For a different sort of alien feeling, see InhumanEmotion.

When the bizarreness applies to the way the alien communicates, it's StarfishLanguage.



[[folder: Comic Books]]

* ComicBook/MartianManhunter occasionally mentions having nine senses.[[note]]Which actually would make him have ''less'' senses than humans (apart from the five classic ones humans also have sense of temperature, balance, kinesthetic, pain and several internal senses like hunger, although the writers were probably thinking in the five traditional ones). [[/note]]
* In the "vegetable sex" scene from ''Saga of the ComicBook/SwampThing'', Abigail temporarily experiences Swamp Thing's ability to sense life force, and perceives the wetlands as a shimmering field of glowing vegetation, dotted with bright life-sparks of animals.
* In ''ComicBook/TheLeagueOfExtraordinaryGentlemen'', Edward Hyde can see people's body heat [[spoiler: including Griffin's]].
* Franchise/{{Superman}} has all kinds of visions, not taking into account [[EyeBeams heat]]. X-Ray, microscopic, electromagnetic (at one point he states that he can see Wi-Fi networks as a series of overlapping clouds), ''soul'' (yeah, that's a thing now).
* ''Comicbook/{{Supergirl}}'''s Kryptonian senses don't care for puny laws of physics. She has at least half-dozen of kinds of super-vision (telescopic, microscopic, X-Ray...) as well as super-hearing.
** In ''Comicbook/SupergirlRebirth'', Kara hears what is happening on Earth in real time while she is standing on the surface of the Sun. And she uses her microscopic vision on Lar-On to observe his genes and determine that his genetic makeup has been completely mangled by Red-K poisoning.
--->'''Supergirl:''' I can see his genes.
* When the Jason Macendale version of the Hobgoblin, a ''ComicBook/SpiderMan'' villain, got turned into a demon, he noted that colors were all wrong.
* Franchise/SpiderMan's SpiderSense is sometimes portrayed as more like an actual sixth sense than a psychic impression (as in the trope of the same name). Apparently it [[CatchPhrase tingles]].
* The Sandlings of ''ComicBook/WhiteSand'' have some sort of "sand sense", and can apparently talk to it, although whether it's low-tech civillization's way of describing echolocation or something more bizarre remains to be seen.

[[folder: Fan Works]]
* ''Fanfic/ACrownOfStars'': The Avaloni Imperial Tribes have especial senses: Star Borns as Ching can feel when others are close and have aura-reading abilities, whereas Blood Borns can feel physical proximity.
* ''Fanfic/AdviceAndTrust'': In chapter 7 Rei fights Zeruel. It is explored how she -an ancient alien goddess stuck inside the body of a human teenager- sees the world differently, how she senses everyone's A T Fields, their nature and their power, and during the battle she feels her Field and Zeruel's clashing, hers struggling uselessly against Zeruel's and Zeruel's menacing with eroding hers if her pressure ever lets up.
* ''FanFic/EternalFlowers'': Seeing as Persocoms are considered another type of lifeformů the list includes sensing not only wifi and radio waves, but mircowaves and even magic as well.
* ''Fanfic/LastChildOfKrypton'': The story goes into great detail about how Shinji -who in this setting is ''Franchise/{{Superman}}''- sees the world in the entire electromagnetic spectrum.
* ''Fanfic/SOE2LoneHeirOfKrypton'': ''[[ComicBook/{{Supergirl}} Asuka]]'''s first hint that her senses were not normal either was when she accidentally saw through her home's walls... [[AccidentalPervert right when Shinji was changing clothes]]. Later she discovered her senses were exceptionally sharp and she had many different kinds of vision... including heat vision.
* In [[https://www.fanfiction.net/s/2698347/1/Walk-Through-the-Valley ''Walk Through the Valley'']] by Creator/{{Vathara}}, the at least three species of animal on the DeathWorld Satoyama can sense and generate {{EMP}}s. Through LegoGenetics, [[Manga/RurouniKenshin Hiko and Kenshin]] gain this ability and then some.
* Ponies in the [[Fanfic/TriptychContinuum Triptych Continuum]] possess ''feel'', which allows them to pick up on active magic use and lingering traces for the workings of their own race, along with helping them learn how new tricks can be done. Most ponies can improve the quality of this sense through practice, although a few seem to be stuck in the basement. It's presumed that the Princesses possess all three versions. [[spoiler: ''[[NoNameGiven She]]'' does as well, but only one at a time.]]
* In ''FanFic/RevengeOfTheEnergyVampire'', [[WesternAnimation/BuzzLightyearOfStarCommand Nos-4-A2]] can sense energy.


[[folder: Film]]

* The ravenous flying beasts from ''Film/PitchBlack'' use echolocation, which is depicted on-screen as textured pixel-clouds that take on the shapes of objects.
* In the ''Film/{{Tremors}}'' franchise, Graboids pinpoint their prey using sound and other vibrations, while Shriekers and Ass-Blasters use heat vision that's enhanced by blasts of heat emanating from their mouths.
* ''Franchise/{{Predator}}'':
** The title aliens have near-infrared vision. This is depicted onscreen by coloring what they see based on the temperature of objects: black = cold, white = hot, and other colors in between.
** In the sequels, video games, and spinoff films, even this is thrown for a loop. When the Predators have reason to believe humans are [[LogicalWeakness using their vision's weaknesses against them]], they reveal that their helmets have technology in them [[NewPowersAsThePlotDemands that gives them ''further'' forms of vision]], such as sonar, backscatter x-ray, and some kind of metal detection. Given the [[CrazyPrepared characterization]] that Predators tend to receive, it rarely feels as arbitrary as it sounds.
* ''Film/{{Wolfen}}'' was probably the first film to incorporate thermographic footage to represent this trope.
* The invaders from ''Film/TheDarkestHour'' sense electricity. [[spoiler: This means they can't see through glass.]]
* ''Film/MenInBlack3'': Griffin lives in 5 dimensions, which gives [[ForWantOfANail him a rather]] [[InSpiteOfANail interesting view of]] [[TimeyWimeyBall time in general]].
* In the film ''Film/KPax'', mental patient/possible alien "prot" (Creator/KevinSpacey) is confirmed early on as being able to somehow detect infrared wavelengths of light.
* ''Film/TheFly1958'': During TheReveal in which his wife pulls off his hood, Andre's P-O-V is briefly shown, and he sees dozens of simultaneous images of her screaming face through his fly-head's compound eyes.
* In ''Film/JawsTheRevenge'', the shark-hunters disorient the great white using a device that confuses its electroreceptive sense.
* The "gorilla wolf" aliens from ''Film/AttackTheBlock'' have no eyes, and are implied to perceive their surroundings by scent and echolocation.
* ''Film/TheForceAwakens'': Steelpeckers, scavenging birds seen in the background of some Jakku scenes, use a magnetic sense to pinpoint the scrap metals they like to consume.
* ''Film/DraculaUntold'': Several POV shots from Vlad's perspective appear to merge both echolocation ''and'' thermographic vision, showing a forest's trees as vague gray silhouettes that sharpen into clarity with every ultrasound-burst, while glowing-red images of warm-bodied soldiers duck and weave among them.

[[folder: Literature]]
* In Creator/PiersAnthony's ''Omnivore'', the fungus-derived mantas use biological radar to "see" their surroundings.
* In ''Discworld/LordsAndLadies'', elves are sensitive to magnetic fields, thus explaining their aversion to iron which distorts and "blinds" such senses.
** Another ''Literature/{{Discworld}}'' example: golems, or at least Mr. Pump, are sensitive to something called "Karmic Signature", which Pump did not see fit to explain. They can also detect one another "singing" underground, through thousands of feet of soil.
** Angua's sense of smell when in her wolf shape verges on this trope, and she's usually forced to draw analogies to colors and sounds in her efforts to convey what it's like to non-werewolves.
** Inverted in ''Discworld/MovingPictures'', when Gaspode complains about what a shock it was when his Holy Wood-induced newfound intelligence caused him to have dreams ''in color''. The experience of Bizarre Human Senses was quite appalling to the little terrier-mix.
* Creator/AlanDeanFoster's ''Literature/HumanxCommonwealth'' setting gives us the insectoid Thranx, who have a "Faz" sense granted by their antennae. Apparently, the antennae are sensitive to air currents.
** One novel includes scenes from the perspective of a thranx ''larva'', who is baffled by the concepts of color vision and scent: senses that don't develop in thranx until adulthood and thus, seem like this trope to him.
** In his novelization of ''Film/{{Aliens}}'', Bishop speculates the xenomorphs have this given their EyelessFace and lack of any other apparent sensing organs for tracking prey.
* The Rigellians in the ''Literature/{{Lensman}}'' books use a bizarre sense that gives a worldview much like the best solid-modeling programs. They can even see things like the innermost components of shielded power reactors.
** The flip side of this is that they rely ''exclusively'' on that sense and lack both sight and hearing. In consequence, it's sheer torture for other species to spend time in their cities, because their cars have no windows, their buildings have no sources of light and they make no attempt whatsoever to avoid loud noises... a visit to Rigel therefore involves a great deal of sitting around in the dark being startled by loud bangs, screams and howls of various kinds.
* The MadScientist Travnicek in ''Literature/WildCards'', after his infection due to Typhoid Croyd, develops a ring of unnatural, horn-like sensory organs around his neck.
* In the ''Literature/{{Dragaera}}'' novels, the tendrils on the necks of [[OurDragonsAreDifferent dragons]] are sensory structures that detect other creatures' psychic energies.
* The Lizards of ''Literature/WorldWar'' can see a few colors in the infrared spectrum.
* The [[spoiler: creators of the Descolada]] in ''Literature/ChildrenOfTheMind'' are also implied to have this.
* The Sphynxian Treecats of the ''Literature/HonorHarrington'' universe are [[{{Telepathy}} telepathic]] and empathic, and are evidently unique in the universe in that trait.
* On ''Literature/{{Gor}}'', the Priest-Kings are an alien insectoid race which "talk," "hear," and mostly "see" by scent, which they perceive via their antennae.
* In "Aftermath", a short story from ''Literature/TheDresdenFiles'', the "turtlenecks" use sonar to navigate in the dark.
** Not quite a ''different'' sense, but the scene in ''Literature/WhiteNight'' in which Harry, hiding from enemies in a large pitch-black room, is shown his surroundings by Lash using mentally-projected outlines of his environment somewhat resembles this trope. It gets particularly alien when he immediately loses 'sight' of an object he throws (because Lash can't tell where it is once he's stopped touching it).
* The aliens in Creator/IsaacAsimov's short story "The Secret Sense" are very sensitive to electric fields, but have comparatively weak hearing and color vision. The brain cells involved are present in humans but do not function. The story centers around a man who is temporarily given the ability to use this sense to experience the electromagnetic equivalent of a musical performance, but the process [[spoiler:eventually kills the cells, depriving him of the secret sense permanently. The alien in the story demonstrates this because he wants the human to shut up and stop talking about Earth music]].
* The extinct aliens in Creator/JohnBrunner's ''Total Eclipse'' were able to sense electric fields. A minor plot point is the protagonist reasoning that the aliens must have lived in constant terror of thunderstorms. He is therefore able to deduce that a bizarre bellows-like gizmo the archaeologists found must have been a device for predicting the weather.
* Kdatlyno from the ''Literature/KnownSpace'' Verse "see" via radar.
* In ''Literature/PerdidoStreetStation'', the eyeless slake-moths can smell and taste the psychic energies of sentient creatures' dreams.
* ''Literature/{{Expedition}}'': Sonar seems to be the primary sensory input for Darwin IV species.
* ''Franchise/StarWars'' [[Franchise/StarWarsExpandedUniverse Expanded Universe]]: Both Saba and Tesar Sabatyne can see in infrared, being Barabels.
** Togruta (like Shaak Ti and Ahsoka Tano) can sense their surroundings via some kind of passive echolocation.
** The Miraluka species are humanoids who lack conventional eyes, seeing entirely through The Force. They're mostly isolationist, but the ones who leave their homeworlds tend to end up with the Jedi in some form; either as Jedi themselves, or adjuncts in teaching or administrative positions. As a courtesy to non-Miraluka, they cover their {{EyelessFace}}s with hoods, masks, or bands.
* In the Hal Clement short story "Uncommon Sense", the alien creatures on an airless world see/smell through pinhole camera eyes. The molecules that escape from objects travel in straight lines, so they can be resolved into a meaningful image, which the beings "see". Does that volatile hunk of rare metal have a pungent odor--or a brilliant color?
* In the ''Literature/{{Animorphs}}'' series Andalites are said to have the ability to keep time perfectly and are able to tell cardinal directions. Also, according to Ax, their stalk eyes can see into the infrared spectrum.
* The Slan in ''Literature/StarCarrier: Deep Space'' see almost exclusively by echolocation. (They do have light-detecting organs, but they can only ''detect'' it: they can't really interpret it the way smarter Earth animals do.) This proves a disadvantage during space combat: hull breaches mean air leaks out of the ship, meaning the Slan can't see or communicate. It also means that they don't really understand the concept of "space". It took them a ''really'' long time to find out about the existence of stars, and only when they built photosensitive devices that translate visual images into understandable sounds. Despite being a space-faring race, they still perceive space as a really-really big cave with a few habitable "islands" (i.e. planets) scattered in it. They don't quite understand the technology they use, implying that someone gave it to them. When they first meet a human female face-to-face (sort of), their captain tries to use echolocation to figure out human organs. He's confused why the human sound-emitting organ (mouth) doesn't have the same flexibility as the Slan equivalents. He tries to find the sound-receiving organs and, ignoring the ears, settles on boobs (also noting they're not very flexible). When contacting Grey, the Slan captain assumes that Grey is blind because he lacks the "sound-receiving organs".
* According to some ''Franchise/StarTrek'' [[Franchise/StarTrekExpandedUniverse Expanded Universe]] novels, Andorian antennae aren't just for show. They allow Andorians to have a limited "electro-vision", which is how an Andorian crewmember aboard the [=DS9=] is able to detect a [[InvisibilityCloak shrouded]] Jem'Hadar.
* The Spiders in Creator/VernorVinge's ''[[Literature/ZonesOfThought A Deepness in the Sky]]'' have a larger visible spectrum of light than humans, referring to infrared frequencies as "far-red" and ultraviolet as "far-blue". Human display technologies, designed only to display what we can see, look like simple and underdeveloped technology to them, despite our otherwise advanced capabilities. Some Spider dwellings also appear dark to us, due to being lit with light outside our visible spectrum. On one occasion, Spiders are also shown to be able to "hear" vibrations in the ground through their feet.
* The [[{{Kaiju}} Endbringers]] in ''Literature/{{Worm}}'' perceive the world through their powers: Behemoth senses tremors, Leviathan senses water, and the Simurgh senses the past and future. [[spoiler: Khonsu senses distortions in time, Bohu also senses tremors, and Tohu senses powers.]] It's implied that they have no senses beyond this, [[spoiler: since their eyes (and pretty much everything else) are cosmetic. Also, [[EldritchAbomination Scion]] can sense everything around him through unknown means, and can see through the eyes of parahumans because they have his cells connected to them]].
* In Creator/StephenKing's ''Literature/TheEyesOfTheDragon'', a chapter from the point of view of a dog explains its sense of smell by metaphor with colors (the scent of a friendly character he's tracking is described as an exciting electric blue) and sounds (comparing summertime, with many different smells, as a cacophony that makes it difficult to focus on any one scent compared to the relatively "quiet" wintertime). This latter is a misconception, incidentally; dogs, especially ones bred for tracking like this one, are ''far'' better at picking out a single scent out of many others than humans, and wouldn't lose track of a single significant scent any more than you or I would lose track of a single bright red thread woven through an otherwise white cloth.
* ''Literature/TheStormlightArchive'':
** Windrunners like Kaladin have an ill-defined ability to sense wind currents, which is a passive ability separate from the more active Surges. Not only does this aid them in their NotQuiteFlight, but it allows them to predict the flow of battle in ways other people cannot match. In [[Literature/WordsOfRadiance the second book]], [[spoiler:this almost gets Kaladin killed in his first fight with Szeth. He lets his windsense guide his strikes, only to be taken completely off guard when Szeth easily counters his move. This implies that the Windrunner Honorblade that Szeth is using grants this same ability--or maybe Szeth is just ''that'' good]].
** A few in the third book, ''Literature/{{Oathbringer}}'':
*** Lift can apparently ''smell'' when someone has visited the Nightwatcher.
*** Syl is surprised to discover that she can sense when a highstorm is coming, even when it's still days off. When Kaladin was in the warcamps, she didn't need to exercise this ability since there were always lists of when the next few storms would be.
*** Shallan and [[spoiler:Renarin]] can both feel Re-Shephir somewhere deep in the tower, long before they actually find her. Due to her connection to Lightweaving and the fact that Dalinar couldn't sense her, it's possible that their power over the Surge of Illumination granted them this ability.
* ''Literature/TheTraitorSonCycle'': dragons have some form of magic-based sense that works akin to echolocation - their roars resonate through the ethereal, letting them detect their prey.
* ''Literature/LesXipehuz'': While it's clear that the Xipéhuz percieve their environment, the protagonist never finds out how they do it, as they have no visible sensory organs and know about humans and other Xipéhuz even if there is something between them.
* In Creator/IsaacAsimov's short story "Green Patches", aka "Misbegotten Missionary", life forms on Saybrook's Planet have tufts of green hair-like structures on their surface, which allow them to sense the interconnections that link all life forms on their world into one vast gestalt consciousness. [[spoiler: Earth organisms - everything from bacteria to plants to the next generation of animals - develop these same green patches ''in place of eyes'' if exposed to Saybrook biota.]]
* In ''Literature/TheFifthSeason'', human brain stems have sensory organs called sessapinae, which give them a limited ability to sense vibration and seismic phenomena. Humans born with the FunctionalMagic of orogeny have a vastly more powerful ability to "sess" things like the exact composition and stratification of the earth for miles around, text written on stone (likened to reading a page blindfolded by tasting the ink), distant conversations spoken near rock, and so on.

[[folder: Live Action Television]]

* ''Series/{{Daredevil 2015}}'': Matt Murdock sees "a world on fire", having lost the use of his eyes but gained a dozen other ways of seeing the world in shades of pressure and heat.
* In ''Film/AlienPlanet'' (an adaptation of Creator/WayneBarlowe's ''Literature/{{Expedition}}''), the life forms of Darwin IV lack eyes and rely on a combination of sonar and thermographic senses to discern their environment. Justified as a consequence of Darwin IV's having been extremely foggy in the recent evolutionary past, which made eyesight a liability.
* The Skitters on ''Series/FallingSkies'' communicate with radio waves, which both they and the children they've Harnessed can detect.
* The "future predators" on ''Series/{{Primeval}}'' use echolocation, represented on-screen with distorted false-color imagery and concentric, pulsing rings of sonic energy.
* ''Series/DoctorWho'':
** The Doctor has some kind of "Time Sense" relating to whether or not an event is irrevocably supposed to happen. He has also been shown to be able to slow down his own perception of time. In addition to that, he can taste and smell a host of things that humans can't, such as the blood group in a sample of blood and how old an object is.
** Time Lords have also shown a heightened sensitivity to gravity; in "Kill the Moon" the Doctor immediately realizes that the Moon has far more gravity than it should, and in "The Magician's Apprentice" both the Doctor and Missy know that they are on a planet instead of a space station because they can tell that the gravity is natural instead of artificial.
** A human variant is shown in "Before The Flood", when Cass, who is deaf, touches the floor and ''feels'' the vibrations of the ax which Mason's ghost is dragging towards her. The shapes of floor, walls, and the ax-head are traced out in spreading bright lines across a black background.
* Occasionally, a PoliceProcedural will illustrate a police dog's Bizarre Canine Senses using CGI light-trails that represent the trail of odor it's following.
* In ''Series/TheFlash2014'', [[Characters/SecretSix King Shark]] has an enhanced version of a shark's electrosense, which works even on land, although the only person he's shown being able to track this way is Barry, who tends to give off a lot of electricity when running. So Barry might look like a giant flare to King Shark, even at a distance and inside a dwelling. During their climactic battle, Barry creates an electric maelstrom in the water that confuses King Shark's senses and then zaps him with lightning bolts until he's stunned.
* Cig's entry in the "Intergalactic Congress" episode of ''Series/FaceOff All-Stars'' had heat-sensitive facial pits rather than eyes.

[[folder: Mythology]]

* The Jiangshi, or ChineseVampire, is known to hunt by a person's breathing. Holding your breath makes them unable to find you.


[[folder: Play By Post Games]]

* ''Roleplay/{{Leyline}}'': Alexis can echolocate, 'seeing' the world through sonar.


[[folder: Tabletop Games]]

* A common one in ''TabletopGame/DungeonsAndDragons'' is [[InnateNightVision darkvision]], the ability to [[ExactlyWhatItSaysOnTheTin see without any light]]. Earlier editions used vision that extended into the infrared or ultraviolet spectra instead. More exotic senses include blindsense (many forms, including echolocation), the much more precise blindsight, tremorsense (feeling vibrations in the ground), mindsight (detecting self-aware beings), [[AuraVision lifesense]]...
* ''TabletopGame/{{Shadowrun}}'': Certain Awakened creatures have thermographic (infrared) vision, including dwarves, trolls, dragons, vampires, centaurs, cerberus hounds and fomorians.
* Native creatures of the ''[[TabletopGame/SkyrealmsOfJorune Jorune]]'' game setting [[EyelessFace have no eyes]], sensing their surroundings by an awareness of mystical energies.
* ''TabletopGame/{{Traveller}}'' Double Adventure ''The Chamax Plague/Horde'': The Chamax have two sensory abilities humans don't have. First, they can detect radio waves and use triangulation to determine their point of origin. Second, they have a limited ability to detect life, which they use to search for food.
* In ''TabletopGame/RocketAge'' the long dead Lunans are believed to have seen through echolocation. The Jovians can smell certain dangerous gas pockets, an important ability on Jupiter.


[[folder: Video Games]]

* The [[{{Precursors}} Protheans]] in the ''Franchise/MassEffect'' universe had the ability to read the memories of other living beings and even inanimate objects by perceiving "experience markers". This is revealed by [[spoiler:the Prothean squadmate Javik]] in ''VideoGame/MassEffect3''. [[spoiler: Javick expresses surprise none of the current races could do it despite being otherwise on a similar technology level to the Protheans, suggesting it might not be a natural ability at all but some kind of communication technology.]]
* The Orz from ''VideoGame/StarControl'' say that they *smell* their environment. The Orz don't actually smell as their primary sense, it's just the least-wrong translation possible for the concept of exactly how they are sensing their surroundings. The Arilou also work hard to keep something from *smelling* the Humans, which imply they have a similar means of detection, mechanical or not.
* In ''VideoGame/KnightsOfTheOldRepublicIITheSithLords'', the team bounty hunter can give a short lecture on the Bith (the bulb-headed aliens that tend to be musicians in most bars). Apparently their aural perception covers a much wider spectrum than humans', including some radio signals. However, this makes them extra vulnerable to noise and a flashbang will kill them messily. One sidequest involves trying to hunt the source of a nearby radio signal for one, simply because it's transmitting through his apartment and the noise is driving him nuts.
** Also from KOTOR 2, one of your companions is a Miraluka, a race that evolved a highly attuned connection to the Force in lieu of eyesight. The race was previously shown in ''VideoGame/JediKnightDarkForcesII'', where the BigBad Jerec is a powerful Miraluka Dark Jedi.
* The Progenitors in ''VideoGame/SidMeiersAlphaCentauri'' can sense and manipulate a variety of fields, including electromagnetism. They communicate through "altering," too. While humans generate patterns of sounds, progenitors alter existing background noise and it's how they alter those sounds that determines meaning. This phenomenon is called "Resonance" in the game.
* ''VideoGame/EccoTheDolphin'', being a toothed cetacean, can 'look beyond his eyes with his song' i.e. use echolocation. It's depicted as summoning a map of the area. There's a level in the second game called Sea of Darkness that requires echolocation to navigate, depicted by lightening the area every time Ecco sings.
* ''VideoGame/DiscworldNoir'': Gaspode teaches Lewton how to use [[spoiler: werewolf "nasal vision"]].
* ''VideoGame/{{Oddworld}}'': Lacking eyes, Scrabs sense electrical impulses to find their prey, and Paramites navigate primarily through smell, rather than vision.
* ''VideoGame/StarWarsTheOldRepublic'': All of Vector's senses are sharper than those of an ordinary human, and that's not even counting the ones that humans don't even have in the first place. Miraluka (see above) are also a playable race, defaulting to the Jedi classes, but unlockable.
* The VideoGame/{{Pokemon}} Dedenne has the ability to communicate with other Electric-types by sensing their electricity. The anime expands on this and has them even able to recognize individuals by their electric signature.
* In the world of ''VideoGame/TamingDreams'', everyone has a characteristic of their soul referred to as a sentiment, and people can perceive each others' sentiments effortlessly.
* In ''Videogame/{{Evolve}}'' the monsters are capable of sensing [[spoiler: the distortions in reality caused by Patterson tech]].
* Later stages of infection in ''VideoGame/TheLastOfUs'' are dependent upon echolocation, as fungal growths around and over the face block off the host's vision.

[[folder:Web Animation]]

* ''WebAnimation/{{Dreamscape}}'': Jenna's Skull Snake has thermal vision. Not even the way snakes sense body heat using their facial pits like in RealLife; its just like straight-up thermal goggles.

[[folder: Web Comics]]

* ''Webcomic/{{Homestuck}}'' plays with this. After Terezi lost her normal eyesight, she learned how to taste and smell colors to compensate. But when she contacts the human protagonists, she messes with them by claiming that ''all'' Alternians share her abilities.
* In ''Webcomic/ArthurKingOfTimeAndSpace'', fairies and Olympians can see ultraviolet.
* In ''Webcomic/IWasKidnappedByLesbianPiratesFromOuterSpace'', the main characters tend to have antennae. WordOfGod is that these are for some bizarre sixth sense which [[HandWave humans don't understand]].
* ''Webcomic/{{Melonpool}}'': Melotians pick up [[AliensStealCable Earth television signals]] through their antennae. [[HilarityEnsues Couch potatoness ensues]].
* ''Webcomic/QuentynQuinnSpaceRanger'' discusses the trope [[http://www.rhjunior.com/QQSR/00053.html here]] as regards to AlienArtsAreAppreciated...and [[http://www.rhjunior.com/QQSR/00072.html here]] [[CrowningMomentOfFunny as relates to]] DrivesLikeCrazy.
-->'''Rasheed:''' Hoo! Drive wit' me ''eyes?'' I can't see more den ten meters wid dese, brah. I use electromagnetic proprioreception. ''Much'' better dan eyes.
* In ''Webcomic/ElGoonishShive'', magic itself is sapient and aware. It doesn't have any senses - its only awareness of the world relates to how spellcasters use it.
* Skitter in ''Webcomic/{{Drive}}'' can perceive gravity using his "mohawk" crest, which allows him to avoid space debris when piloting starships at FTL, hence why the Empire wants to find his homeworld.

[[folder: Western Animation]]

* As Wildmutt, ''WesternAnimation/{{Ben 10}}'' [[EyelessFace lacks eyes]], yet still experiences "images" of what's around him. This perception is probably scent-based, as the images grow sharper when he takes a breath.
** Clockwork from ''WesternAnimation/Ben10UltimateAlien'' has a temporal sense that sees into the past. He can project this effect into a whole area by winding the key on his head.
* Non-alien example: When the students from ''WesternAnimation/TheMagicSchoolBus'' are turned into bats, they experience what echolocation is like, perceiving strobe-like flashing views of their surroundings each time they emit a sonar-cry.
* Some [[DishingOutDirt Earthbenders]] on ''WesternAnimation/AvatarTheLastAirbender'' use their abilities to sense vibrations in the ground. This also enables them to [[LivingLieDetector detect lies]] by picking up on stress-induced changes in other people's breath and heartbeat -- though it [[NoSell doesn't work]] if someone is enough a ConsummateLiar to deceive people without a second thought.


[[folder: Real Life]]

* Some fishes can sense electricity. Such electroreception is found in lampreys, cartilaginous fishes (sharks, rays, chimeras) and in some varieties of bony fish.
** The platypus has this too, as does at least one species of freshwater dolphin.
* Echolocation is well-known in bats and toothed cetaceans. Shrews also use this means of sensing, as do cave swiftlets and oilbirds.
** Subverted with flying foxes and baleen whales, which don't use sonar even though most people assume all bats or whales do.
** Some humans have been able to develop an echolocation sense [[DisabilitySuperpower after their eyesight was permanently impaired]].
* Thermographic "vision" is found in pit vipers, many boas and pythons, and vampire bats.
* On the other end of the scale from thermovision is UV vision, common to insects and other arthropods.
* The eyes of Mantis Shrimp have 12 types of cells to detect light of different color, which is four times as many as human eyes have, giving them a range of colors from Ultraviolet to possibly Infrared. In addition, they also have 4 more types of cells that detect other aspects of light than color, like polarization. This allows them to see through the glare of light reflections and even to objects that are perfectly transparent. While still retaining their ability to see colors behind them.
* Fish detect motion in the water with their lateral lines.
* Magnetoception, the ability to detect magnetic fields, is found in a wide variety of creatures, from certain kinds of bacteria to certain kinds of mammals. Homing pigeons are particularly well known for it.
* The whiskers of cats and other mammals are merely a tuned-up human sense (touch), but as with dogs' noses, they ''seem'' almost to be a separate sense.
* Rats and mice have a sense of smell that's not only vastly more discerning than that of humans, but which can distinguish the direction from which each individual aroma is coming, with no need to turn or wander around to determine where it's stronger. Thus, their ''experience'' of smell is probably more like how we experience sound or vision than aromas.
* Owls have insanely good eyesight, but it's their hearing that edges into a whole new sense. They use hearing together with sight as a primary hunting tool. Their feathers are shaped to maximize the amount of sound they hear, and their ears are offset (one higher than the other) to give them three-dimensional sound perception. Owls can locate their prey by hearing their heartbeat from up to three meters away.
* Internal parasites such as liver flukes often have unique thermo/chemoreceptor organs used to navigate within the bodies of their hosts, so they can settle down in the right organs or move to the lungs, bladder, rectum or nasal passages to release eggs.
* Compared to many other animals, humans are almost entirely lacking any sense of smell. While dogs can smell about 100 times better than humans, the sense of smell of bears is over 2,000 times as good, which allows them to detect and find dead animals from tens of miles away.
* The desman, an aquatic relative of moles, is unique among mammals in being able to smell things underwater. It blows bubbles against the surface of objects it wants to sniff, snares the now-scented bubbles with its webbed feet, and breathes them back in through its highly-flexible short trunk.
* Detailed studies of narwhal tusks have revealed them to have sensory functions, detecting water pressure, salinity, temperature and particulate concentrations.
* Wiki/TheOtherWiki has [[http://en.wikipedia.org/wiki/Sense a whole page]] dedicated to this, as well as mentions of other human senses not typically considered.
