What to do when [[GiveMeASword you're without a weapon]]? PunyHumans must resort to hands and feet (or [[ImprovisedWeapon obtain]] an EmergencyWeapon). On the other hand, non-human races, animals and aliens tend to have claws, stings and other such abilities.

This need not involve claws; stingers or even more complex organic weapons count. As long as they're a natural part of the creature's anatomy.

Compare AnatomyArsenal (which can overlap with this; the arsenal is literally part of the user's anatomy), LivingWeapon (when the weapon is part of another creature entirely).

Any of the following could count

...[[TropesAreFlexible but not always.]]
----
!!Examples:

[[foldercontrol]]

[[folder: {{Anime}} and {{Manga}}]]
* Dozens of examples can be found in the released forms of Arrancars in ''Manga/{{Bleach}}''. They carry around swords, but in "resurreccion" mode most arrancars' zanpakuto become natural weapons. They may have claws, pincers, tentacles, wings, tails, or horns that will be used to fight.
* Garyuu of ''Anime/MagicalGirlLyricalNanohaStrikerS'', who in addition to his speed and strength, is capable of firing mana bullets as part of his biological functions, has retractable blades up the wazoo, and combat tentacles that could slice through Barrier Jackets. These, together with his other [[{{Flight}} natural]] [[{{Invisibility}} abilities]] and human-level intelligence, make him the equivalent of a skilled mage and one of the strongest amongst of Lutecia's [[BigCreepyCrawlies insect]] [[SummonMagic summons]].
[[/folder]]

[[folder:ComicBooks]]
* One ''ComicBook/XMen'' villain, Riptide, could secrete hardened resin from his skin and fire it as projectile weapons at his foes.
** {{Wolverine}} and {{X-23}}'s...WolverineClaws are also made of bone, although they both have [[{{Unobtanium}} adamantium]] attached to them (Wolverine on his whole skeleton, X-23 just on her claws) to make them much more dangerous.
[[/folder]]

[[folder: {{Film}}]]
* ''Film/ResidentEvil'': The Licker mutant had huge claws that could rip through solid metal and inflict grievous wounds. Its bite attack was also fairly impressive.
* The xenomorphs of the ''Franchise/{{Alien}}'' series. Extensible teeth, tremendously powerful arms, acid for blood, prehensile tail. Par for the course, since they were created as {{Living Weapon}}s in the expanded universe.
* The bug aliens of the ''Film/StarShipTroopers'' movie series were able to poop city-destroying plasma across interstellar distances; the novel version built weapons just like people do.
[[/folder]]

[[folder: {{Literature}}]]
* Lots in ''Literature/{{Animorphs}}''. Andalites have a scythe blade at the end of their tails, and Hork-Bajir are covered head to toe in spikes. Humans are considered particularly vulnerable in large part because we don't have any.
** Bit of a subversion on the Hork-Bajir -- despite appearing to be a walking knife factory, they're a peaceful race and use the blades to cut and eat tree bark. As long as they aren't being controlled by a Yeerk.
* Many flavors of [[Literature/MoreauSeries moreaus]] have them, mostly claws and teeth. Angel Lopez' legs may count; as an engineered rabbit the size of a small human, she has a kick that can shatter bones.
* Happens frequently in ''Literature/{{Redwall}}'', since most animals have at least some natural defenses they can bring to bear. Examples include:
** ''Redwall'': Constance the badger who uses her sheer bulk to overpower the cutlass-armed [[YouDirtyRat Redooth]]. Asmodeus Poisonteeth, being an adder, and therefore legless, has no choice but to use his fangs and coils as his main weapons. And the sparrows attack with beak and talon alone.
** ''Mossflower'': [[TheBigBad Tsarmina]], unarmed and confronted by a fully armed and armoured Martin the Warrior, attacks him with only her teeth and claws. Since she's a wildcat and he's a mouse, she damn near kills him anyway.
** Lask Frildur and his monitor lizards in ''Pearls of Lutra'' who use only their claws and fangs.
** ''Rakkety Tam'' has Gulo the Savage, a wolverine who fights using only his claws, teeth, and size.

[[folder: TabletopGames]]
* The TropeNamer is ''DungeonsAndDragons'', where "natural weapon" is a special ability for monsters.
* The Tyranids from ''TabletopGame/{{Warhammer 40000}}''. They not only have various types of claw weapons, several units have organic projectile weapons integrated into their bodies.
* Lots of them in ''{{GURPS}}''. Innate Attack is the most common (since it can represent thousands of different things) but the list includes: Strikers, Claws, Teeth and Spines.
* Present and [[MinmaxersDelight very desirable]] in the ''TabletopGame/LegendSystem''. They gain something of a power boost from the fact that they - and, by extension, their properties - are always active and available even with another weapon drawn. This allows you to have an active weapon loaded to the gills with defensive properties while still having a strong attack freely available. Most tracks that grant them are also built around supporting them.
* Everyone in ''TabletopGame/{{Ironclaw}}'' has at least one, how effective it is depends on their brawling skill and their [[SlidingScaleOfAnthropomorphism species stat]].
[[/folder]]

[[folder:VideoGames]]
* In ''Franchise/TheElderScrolls'' series, the cat-like Khajiit get a bonus to their unarmed skill because of their claws.
* [[CatGirl Taokaka]] and the rest of the [[AttackAnimal Kaka]] clan from ''VideoGame/BlazBlue'' have organic {{magitech}} claws that can absorb and use [[TheCorruption Seither]], something for which most of the other characters need weapons.
* In ''VideoGame/HalfLife1'', Xen aliens have "natural" weapons galore. Vortigaunts can produce huge bolts of directed electricity. Grunts have [[BeeBeeGun hornet]] [[LivingWeapon guns]], which seem to be some sort of insect hive that they've managed to turn into a weapon. Controllers can shoot balls of energy (ball lightning?) and the Nihilanth shoots these as well as teleport portals.
** In ''Opposing Force'', you have the Race X aliens: pit drones, which shoot some sort of biological darts from their forehead, the shocktroopers, which like the Xen grunts use two more forms of biological weapons (shock roaches and spore launchers), voltigores, which like Xen vortigaunts can shoot massive charges of electricity, the pit worm, which can fire a laser from its eye, and the gene worm, which can fire a chemical stream from its mouth.
* The Zerg in ''StarCraft'' are made of this trope... [[LivingWeapon literally]].
* The Laguz in VideoGame/FireEmblemTellius and [[OurDragonsAreDifferent Mamkutes]] elsewhere in the ''FireEmblem'' series. The former use claws, beaks, etc. while the latter use {{Breath Weapon}}s.
* Several species of ''{{Pokemon}}'' base moves around their anatomy. Bulbasaur is famous for moves like Vine Whip and Bullet Seed, which use the bulb on its back; Octillery's signature move is Octazooka, which uses its mouth as an artillery piece, and so on. A full list would take up the entire page.
* Interestingly averted in ''KnightsOfTheOldRepublic''. Wookiees have claws and they use them as tools, but are not allowed to use them as weapons, because only animals do that. Any wookie that fights with his claws is branded a mad-claw and banished.
* Baraka, from ''MortalKombat'', is a member of the Tarkatan race, which have retractable blades in their arms. These blades serve many violent purposes, such as chopping off heads and impaling Torsos.
* Pretty much any creature more powerful than a zombie in ''Franchise/ResidentEvil'' will have these; various formerly human [[ZombieApocalypse T-Virus]] mutants (from Crimson Heads to Tyrants) tend to grow claws as they mutate. [[BodyHorror G-Virus and Nemesis]] mutants gain CombatTentacles. [[PeoplePuppets Las Plaga]] have their own natural weapons when they leave their human hosts. Animals infected by any of these naturally keep their own examples as well.
* All of the weapons you can get in ''{{Evolva}}''. The genohunters' limbs (sometimes the neck or the back) transform each time you select a weapon, as you shoot at the enemies using the transformed limb.

[[folder: WebOriginal]]
* Some of the [[PettingZooPeople anthropomorphic animals]] in ''DarwinsSoldiers'' have natural weapons. Most of the time, it takes the forms of teeth, claws and muscle but snakes in this universe possess ''working'' venom glands.
[[/folder]]

[[folder: RealLife]]
* RealLife: The cone shell can fire a neural-toxic laced harpoon. [[http://www.youtube.com/watch?v=LcBKH7s4SVQ Seriously]].
* Skunks have a well-known natural chemical weapon, spraying a substance that smells so foul, other animals fear it.
** Bombardier Beetles take that UpToEleven, spraying a boiling chemical to severely burn targets.
* The [[http://www.youtube.com/watch?v=XC6I8iPiHT8 Pistol Shrimp]] has the sonic equivalent of a .22 caliber bullet ready to fire as its main weapon (It's been known to shoot its way out of aquariums this way). This shrimp, AKA the Mantis shrimp, has a less badass version which is capable of beating the living CRAP out of a clam, hermit crab, and pretty much anything else you can find on youtube.
* Venomous snakes and monitor lizards have natural PoisonedWeapons.
%%Please don't add bare hands as a Real Life example, there's already a trope for that (also, they aren't technically intended as weapons, they can merely be used as such with training).
[[/folder]]

[[folder:WesternAnimation]]
* Most of TheHerculoids have at least one of some kind.
