A claw is a curved, pointed appendage found at the end of a toe or finger in most amniotes ( mammals , reptiles , birds ). Some invertebrates such as beetles and spiders have somewhat similar fine, hooked structures at the end of the leg or tarsus for gripping a surface as they walk. The pincers of crabs , lobsters and scorpions , more formally known as their chelae , are sometimes called claws.

120-789: A chela are called chelipeds . Chelae are also called pincers . Foster-Miller TALON The Foster-Miller TALON is a remotely operated , tracked military robot designed for missions ranging from reconnaissance to combat . It is made by the American robotics company QinetiQ-NA , a subsidiary of QinetiQ . Foster-Miller claims the TALON is one of the fastest robots in production, one that can travel through sand, water, and snow, as well as climb stairs. The TALON transmits in color, black and white, infrared , and/or night vision to its operator who may be up to about 3,937 ft (1,200 m) away. It can run off lithium-ion batteries for

150-568: A maximum of seven days on standby before needing to recharge . It has an 8.5-hour battery life at normal operating speeds, two standard lead batteries providing two hours each, and one optional lithium ion providing an additional 4.57 hours. It can withstand repeated decontamination, allowing it to work for extended periods of time in contaminated areas. It was used at Ground Zero after the September 11 attacks , working for 45 days under contaminated conditions without electronic failure. This led to

180-548: A point. A nail that is big enough to bear weight is called a " hoof ". (Nevertheless, one side of the cloven-hoof of artiodactyl ungulates may also be called a claw). Every so often, the growth of claws stops and restarts, as does hair . In a hair, this results in the hair falling out and being replaced by a new one. In claws, this results in an abscission layer, and the old segment breaks off. This process takes several months for human thumbnails. Cats are often seen working old unguis layers off on wood or on boards made for

210-419: A sharp point are called nails instead. Claw-like projections that do not form at the end of digits but spring from other parts of the foot are properly named spurs . In tetrapods , claws are made of keratin and consist of two layers. The unguis is the harder external layer, which consists of keratin fibers arranged perpendicular to the direction of growth and in layers at an oblique angle. The subunguis

240-578: A single claw as "spurs" on each side of the anal opening. Lizard claws are used as aids in climbing, and in holding down prey in carnivorous species. A talon is the claw of a bird of prey , its primary hunting tool. The talons are very important; without them, most birds of prey would not be able to catch their food. Some birds also use claws for defensive purposes. Cassowaries use claws on their inner toe (digit I) for defence and have been known to disembowel people. All birds, however, have claws, which are used as general holdfasts and protection for

270-501: A small console to remotely control the robot. Foster-Miller are currently at work on a " Game Boy " style controller with virtual-reality headsets for future operators. In 2007, three SWORDS units were deployed to Iraq. The units were each armed with an M249 machine gun. This deployment marked the first instance of robots carrying guns into battle; however, the United States Army never gave authorization to use them so

Claws are used to catch and hold prey in carnivorous mammals such as cats and dogs , but may also be used for such purposes as digging, climbing trees, self-defense and grooming , in those and other species. Similar appendages that are flat and do not come to

330-400: Is retractable is protected from wear and tear. Most cats and dogs also have a dewclaw on the inside of the front paws. It is much less functional than the other claws but does help the cats to grasp prey. Because the dew claw does not touch the ground, it receives less wear and tends to be sharper and longer. A nail is homologous to a claw but is flatter and has a curved edge instead of

360-615: Is the softer, flaky underside layer whose grain is parallel to the direction of growth. The claw grows outward from the nail matrix at the base of the unguis and the subunguis grows thicker while travelling across the nail bed . The unguis grows outward faster than the subunguis to produce a curve and the thinner sides of the claw wear away faster than their thicker middle, producing a more or less sharp point. Tetrapods use their claws in many ways, commonly to grasp or kill prey, to dig and to climb and hang. All carnivorans have claws, which vary considerably in length and shape. Claws grow out of

390-475: The African clawed frogs . Claws evolved separately in the amphibian and amniote ( reptiliomorph ) line. However, the hairy frog has claw analogues on its feet; the frog intentionally dislocates the tips of its fingers to unsheathe the sharp points of its last phalanges .

Aye-ayes have functional claws on all other digits except the hallux, including a grooming claw on the second toe. Less commonly known, a grooming claw is also found on the second pedal digit of night monkeys ( Aotus ), titis ( Callicebus ), and possibly other New World monkeys . Most reptiles have well-developed claws. Most lizards have toes ending in stout claws. In snakes, feet and claws are absent, but in many boids such as Boa constrictor , remnants of highly reduced hind-limbs emerge with

It is the only robot used in this effort that did not require any major repair. Foster-Miller claims the Talon was used for a classified mission by US Special Forces in the war against the Taliban in Afghanistan , as well as in an EOD role. In Iraq , its standard role has been performing EOD and IED destruction missions. Its combat SWORDS version

690-513: The price may drop to between $ 150,000 and $ 180,000. There are a variety of different weapons which can be placed on the SWORDS, which include the M16 rifle , 5.56 mm SAW M249 , 7.62mm M240 machine gun , .50 Cal M82 Barrett rifle , six barreled 40 mm grenade launcher and quad 66mm M202A1 FLASH incendiary weapon . SWORDS units are not autonomous, but instead controlled by a soldier using

720-525: The purpose. Ungulates' hooves wear or self-trim by ground contact. Domesticated equids ( horses , donkeys and mules ) usually need regular trimming by a farrier , as a consequence of reduced activity on hard ground. Primate nails consist of the unguis alone, as the subunguis has disappeared. With the evolution of grasping hands and feet, claws are no longer necessary for locomotion, and instead most digits exhibit nails . However, claw-like nails are found in small-bodied callitrichids on all digits except

Outside of the cat family, retractable claws are found only in certain species of the Viverridae (and the extinct Nimravidae ). A claw that

810-484: The tip of the digits. The hoatzin and turaco are unique among extant birds in having functional claws on the thumb and index finger (digits I and II) on the forelimbs as chicks, allowing them to climb trees until the adult plumage with flight feathers develop. However, several birds have a claw- or nail-like structure hidden under the feathers at the end of the hand digits, notably ostriches, emus, ducks, geese and kiwis. The only amphibians to bear claws are

C-TALON is an unmanned robot designed to be used in both land and water environments. It is specifically designed for turbulent water environments, coastal waters, and limited access harbors. It has high-resolution imaging sonar , among other key features. The robot costs approximately $ 6,000,000 in its standard form. Foster-Miller

870-849: The weapons were not used in combat. The Army stopped funding the SWORDS robots after deploying the initial three robots. Foster-Miller is working on a successor: the Modular Advanced Armed Robotic System (MAARS). By August 2013, the Smithsonian Institution had acquired a SWORDS robot for its collection. One is also on display at the National Infantry Museum in Fort Benning , Georgia . The Talon has been deployed in military service since 2000 - for example, in Bosnia for
