[[quoteright:300:http://static.tvtropes.org/pmwiki/pub/images/sharktopus_8585.jpg]]

A Creator/SciFiChannel Original Movie released September 25, 2010, this film centers on the rampage of a half-shark half-octopus whose handlers have lost control of it.

The film would later go on to inspire ''Piranhaconda'', a sort of SpiritualSuccessor in 2012. Currently two sequels to Sharktopus are in development. The first sequel, ''Sharktopus vs Pteracuda'' was aired August 2, 2014 on Syfy.

----
!!This film contains examples of:

* AllPartOfTheShow: Some of the beachgoers, including a pair of women and a father and son, wonder aloud if one of the titular character's attacks is all part of a show. One obnoxious teen lingers even after it starts eating people on-stage, snickering and saying "Awesome!".
* AlwaysABiggerFish: In the beginning of the film a beach girl is attacked by a shark while swimming off the shoreline, but the Sharktopus saves her by devouring it.
* ArtisticLicenseBiology: A surprising amount, even for a movie about a mix-and-match critter made up of two totally unrelated creatures.
** If any evidence of a octopus mouth shows up [[http://scienceblogs.com/pharyngula/2010/07/sharktopus_is_coming.php this post]] by biologist P.Z. Myers mentions that [[AHeadAtEachEnd a creature with two mouths and no method of waste disposal]] will eventually explode.
** Also, a more minor point - an octopus doesn't have the tentacular clubs at the end of its arms. A squid does, but "Sharkquid" just doesn't have the same ring to it.
** How did the Sharktopus breathe on land? Is it part [[SaturdayNightLive landshark]]?
** Heck, how does it even ''swim''? It doesn't have a shark's tail ''or'' a cephalopod's siphon for propulsion; it just waggles its tentacles around slightly and at random.
** The "egg case" which the second film's sharktopus comes from doesn't look anything like an actual mermaid's purse. Octopuses lay eggs individually, and great whites (the type of shark which the creature's forebody best resembles) give live birth.
* ArtShift: Sharktopus has a different visual appearance in the sequel.
** Possibly justifiable as the first one having been female (it left an egg case behind) and the second, male.
* AssholeVictim: Quite a few.
* BelligerentSexualTension: Andy and Nicole are less than cordial towards one another when they first meet, and for a while after that, but you can tell they're going to end up together by the end of the movie.
* BerserkButton: [[spoiler:Hurting the marine biologist that raised it is this for the second Sharktopus in the sequel. Both her abusive, greedy uncle (who outright ''says'' he locked her in a closet right in front of it) and the Pteracuda (who is trying to eat her) are attacked presumably for this reason.]]
* BigBad: Vlad in the sequel. While he's working for an offscreen boss, he's the one responsible for Pteracuda's rampage and it's controller throughout most of the film.
* BigNo:
** Screamed by Andy after [[spoiler:Santos' death]].
** The second victim to die directly from the Sharktopus gives a [[DullSurprise pretty nice one]] as he contemplates how he's about to die.
* CombatTentacles: It's called a Sharktopus for a reason. With swords on the tips of its tentacles for [[RuleOfCool some weird reason]].
* CreatorCameo:
** Creator/RogerCorman as the guy taking the old coin found on a beach. It also makes for a funny moment when he [[TastyGold bites the coin to see if it's real]]. Given Corman's legendary...erm, frugality, you can just see him calculating just how many cheap b-movies he can fund with it.
** Similarly, Corman's daughter, Mary Corman, appears as the bungee-jumping girl.
* DenserAndWackier: ''Sharktopus vs Pteracuda'' is even goofier than the original.
* [[EvenBadMenLoveTheirMamas Even Monsters Love Their Mamas]]: [[spoiler:It's implied the second Sharktopus in the sequel starts attacking the Pteracuda to protect the woman that raised it after its control device is destroyed.]]
* [[ThreateningShark Everything's Even Worse With Sharks]]: Yes.
* EverythingsSquishierWithCephalopods: And yes, although the Sharktopus quickly proves that the combo of the two beats out the former.
* FiringInTheAirALot: When tourists disregard warnings of a giant half-shark half-octopus approaching, this is what gets them to leave.
* FlyingSeafoodSpecial: The line of thought on combining a Pteradactyl and Barracuda was "Let's make a weaponized dinosaur out of [=DNA=] [[Franchise/JurassicPark fragments]] sense we need something else to [[LEGOGenetics add we can throw in breathing air and water]], for ... reasons''.
* GiganticAdultsTinyBabies: The sequel's sharktopus is first seen as a hatchling, and its tentacles aren't even a foot long.
* GoneHorriblyRight:
** Nicole created a hunter, but her dad wanted a killer. He changes her programming and everyone ends up paying for it.
** TooDumbToLive: They had a remote control anyway, so there was no reason to make the shark psychotic too.
* HoistByHisOwnPetard: Or rather, by his own Sharktopus.
** Happens in the sequel when [[spoiler:the guy responsible for making the Pteracuda ''and'' releasing the Sharktopus to fight it gets killed by ''both'' at the same time.]]
* ImperialStormtrooperMarksmanshipAcademy: For a guy with a submachine gun, shooting at a 20-some foot tall Shartopus (which tends to remain fairly still while he shoots,) Andy sure manages to miss a LOT of his shots.
* IntrepidReporter: Stacy actively seeks out the Sharktopus so she can cover the story. [[spoiler:Her insistence to get up close and personal with the monster eventually gets both her and her cameraman killed.]]
** Another one appears in the sequel. [[spoiler:She surprisingly lives.]]
* JerkWithAHeartOfGold: Andy seems at first nothing more than a mercenary who loves cheap booze and cheap women, but he later refuses an offer of $1 million to not kill the titular monster. Mind you, [[spoiler:this is just after his best buddy, Santos, is pulled overboard and chewed up]], so Andy has a good excuse.
* ImmuneToBullets: The Sharktopus' main body can withstand machine gun fire. It's tentacles sort of float in and out of it depending on how they want the plot to unfold.
** Same goes for the Pteracuda in the sequel. Bullets don't seem to do more than annoy it.
* ItsBeenDone: Take a look at an earlier film with a suspiciously similar plot (minus the military angle) and a suspiciously similar monster: ''DevilFish'', an Italian ''Film/{{Jaws}}'' ripoff made in the 80's. You know these people are scraping the bottom of the barrel when they rip off a godawful Italian ripoff. Thankfully, this film doesn't take itself as seriously.
* JustThinkOfThePotential: The military sort.
* LampshadeHanging: And how, this movie gets close to a parody of Syfy Channel Original Movies at times.
* MadScientistsBeautifulDaughter
* MindControlDevice: A harness feature of the militarization effort that created Sharktopus and Pteracuda.
* MixAndMatchCritters: Oddly enough, this isn't the only form of entertainment that featured a sharktopus.
** The Pteracuda in the sequel.
* MyEyesAreUpHere: Said by a reporter (Stacy) to the boatman she's trying to hire (Pez) when he ogles her breasts.
* ThePasswordIsAlwaysSwordfish: The kill switch password to destroy the Sharktopus is "Pumpkin", the term of affection that Nicole's father used to call her.
* PlotArmor: The only sensible explanation as to why the Sharktopus is so hesitant to eat Andy at the end, [[spoiler:and the explosion doesn't hurt him when it kills the creature]].
* PreviouslyOn: ''Sharktopus vs Pteracuda'' starts off with a brief recap of the original film.
* RedeemingReplacement: The second Sharktopus is ''much'' less monstrous than the first and while it does kill people, it mainly does so when pissed off (which due to what's done to it, is understandable). [[spoiler:It even protects the woman that raised it from the Pteracuda and kills her abusive uncle.]]
* RoaringRampageOfRevenge: After [[spoiler: Santos, his best friend, gets killed]], Andy spends the rest of the movie trying as hard as he can to kill the Sharktopus in a fury.
* StuffBlowingUp: [[spoiler:Apparently, the best way to kill a Sharktopus.]]
** [[spoiler:Likewise the second film ends with the Pteracuda being blown up, though the Sharktopus survives.]]
* SummonBiggerFish: The plot of the sequel, in which a Sharktopus is unleashed to stop another genetic engineered monster.
* SuperPersistentPredator: Guess who. Justified because the Sharktopus was specifically designed to hunt humans.
** This is shown more directly in the sequel, as the second Sharktopus presumably lacks the original's brain alterations and, due to being raised as an aquarium animal is only aggressive when it's pissed off. Meanwhile, the Pteracuda is stuck on 'kill everything that moves' mode.
* TastyGold: The old man bites the coin he found on the beach to see if it's real.
* TemptingFate: In the opening, [[Film/{{Jaws}} a woman goes swimming in the ocean alone, is stalked by a huge bloodthirsty great white shark]]...[[SubvertedTrope and is "saved" when said shark is grabbed and killed by the title beast]].
* TooDumbToLive: [[spoiler:Stacy has been pursuing the Sharktopus throughout the entire film just to get a scoop, has repeatedly witnessed just how dangerous it is, has already been rescued once before from being eaten alive by a timely intervention of the heroes, and yet ''still'' tries to document it when it already killed her cameraman and is approaching her at the end.]]
* TurnedAgainstTheirMasters: After the device that enabled the scientists to control their project gets smashed, this happens—although it's not so much against its masters as it is against humanity in general.
** Subverted with both monsters in the sequel. The Sharktopus is dangerous, but doesn't go after people specifically until it's royally pissed off and the Pteracuda is largely being controlled by Vlad or doing what it's been programmed to do.
* UnusuallyUninterestingSight: An old man and a woman are on a beach with a metal detector. The woman finds an old coin, and is then grasped by the Sharktopus's tentacles, dragged into the water, and slain (all rather slowly). The man just stands there in DullSurprise mode, waits until she is dead... and then [[{{Jerkass}} goes to get the coin]]. Not out of place at all in a movie like this, though.
* WalkingShirtlessScene: Andy does actually own a shirt, he just never bothers to do it up.
* TheWorfEffect: See AlwaysABiggerFish above.
