Animals with claws use them for far more than fighting. Jaguars grip prey with retractable claws, harpy eagles seize animals with curved talons, iguanas and koalas climb with sharp claws, while moles, anteaters, pangolins and aardvarks turn their foreclaws into powerful digging tools. Claw shape usually reflects the job an animal needs to do: hunt, climb, dig, hold, defend, groom or gain traction.
This guide compares 20 animals with claws across mammals, birds and reptiles. It also explains the difference between claws and talons, why cheetah claws differ from most cat claws, and which animals have some of the most specialized claws in nature.

What Is a Claw?
A claw is a hard, curved structure made largely of keratin that grows from the end of a digit. Claws are related in basic structure to human fingernails and animal hooves, but their shape and function differ greatly between species.
Animals can use claws to:
grip and control prey
climb trees or rock surfaces
dig burrows
tear open termite or ant nests
gain traction while running
hang from branches or cave ceilings
defend themselves
groom fur or feathers
There is no single “best” claw design. A jaguar benefits from sharp retractable claws, while a mole needs broad digging claws and a sloth needs long hooks that fit around branches.
Claws vs Talons: What Is the Difference?
Talons are a specialized type of claw. The word is most commonly used for the sharply curved claws of birds of prey such as eagles, hawks and owls.
A raptor uses its feet as major prey-capture tools. The talons close around prey, helping the bird seize, restrain and sometimes kill it. In contrast, the claws of an iguana are primarily climbing tools, while the claws of a mole are designed for excavation.
So all talons can reasonably be described as claws, but not every claw is normally called a talon.
Predatory Mammals With Claws
Jaguar
The jaguar (Panthera onca) has the classic claw system of a large cat. Its claws can be retracted when not in use and extended during climbing, prey capture or defensive encounters.
Scientific studies of felid claw anatomy show that elastic ligaments help hold the claws in the retracted position. When a cat needs them, muscles and tendons extend the terminal digits and expose the claws.
Retracting the claws helps reduce wear while the animal walks, keeping the tips better suited for gripping prey.
Cheetah
Cheetahs are an important exception to the simple rule that “cats retract their claws.” A cheetah can retract its claws somewhat, but most of each claw remains exposed because the protective claw sheaths found in most other cats are reduced.
San Diego Zoo describes cheetah claws as hard and sharp structures that function like running cleats. The exposed claws improve traction during rapid acceleration and high-speed turns.
This means a cheetah claw is optimized more for traction than for staying needle-sharp for ambush gripping.
Brown Bear
Brown bears have long, strong, non-retractable claws. They use them for digging roots and burrows, tearing apart logs, moving soil, handling food and gaining traction.
Bear claws are impressive because they are multipurpose rather than highly specialized for one single task. Unlike cats, bears do not withdraw their claws into protective sheaths while walking.
Birds With Powerful Talons or Claws
Harpy Eagle
The harpy eagle (Harpia harpyja) has some of the most impressive talons of any living bird. San Diego Zoo reports that its curved rear talons can reach about 5 inches (13 cm), making them larger than the claws of a grizzly bear.
Harpy eagles hunt forest animals such as sloths and monkeys. Their huge feet and curved talons are used to grab and hold prey among rainforest branches.
Harpy eagles have exceptionally large curved talons adapted for seizing prey in tropical forest canopies.
Great Horned Owl
Great horned owls use strong feet and curved talons to seize mammals, birds and other prey. Like other raptors, they capture prey primarily with the feet rather than relying on the beak alone.
The owl's talons work together with quiet flight and excellent hearing. The bird approaches with little wing noise, then closes the feet around the target at the moment of contact.
Southern Cassowary
The southern cassowary (Casuarius casuarius) is not a raptor, but it has one of the most distinctive claws among living birds. The innermost toe carries a long, sharply pointed claw.
The Australian Museum notes that cassowaries can strike with this claw during territorial disputes or defensive encounters. Wild cassowaries usually avoid people when given space, so the claw should be understood primarily as a formidable defensive structure rather than evidence that the bird routinely attacks humans.
Climbing Animals With Claws
Green Iguana
Green iguanas are arboreal reptiles with long toes and sharp claws. The claws improve grip on bark and branches as the animal moves through trees.
This is a good reminder that reptile claws do not have to be weapons. For an iguana, secure footing and climbing traction are the main benefits.
Koala
Koalas have strong hands and feet with sharp claws that dig into eucalyptus bark. San Diego Zoo notes that the hands include two opposing digits that improve grip, while rough pads and claws provide traction.
These features let koalas climb tall trees and move securely along branches while feeding and resting.
Sloth
Sloths have long, strongly curved claws that hook around branches. Smithsonian researchers describe the claws as being made from the same basic keratin material as our fingernails, but shaped to support an upside-down arboreal lifestyle.
The hooked shape lets a sloth hang securely without continuously squeezing a branch with powerful hand muscles. This helps conserve energy.
Bat
Bats use curved hind-foot claws to cling to cave ceilings, tree branches and other roosting surfaces. Many species can remain suspended upside down for long periods with relatively little muscular effort.
Bats also have a claw on the thumb of the wing. Depending on the species, it can help with climbing, crawling around the roost or manipulating surfaces.
Animals With Digging Claws
Star-Nosed Mole
The star-nosed mole (Condylura cristata) is one of the clearest examples of an animal whose claws are built for digging. The forefeet are broad and powerful, functioning almost like biological shovels.
The claws help excavate tunnel systems through wet soils. Here the claw is not mainly sharp because it must pierce prey—it is broad and forceful because it must move earth.
Giant Anteater
Giant anteaters have extremely strong foreclaws. San Diego Zoo describes them using these claws to tear open ant and termite mounds before inserting the long sticky tongue.
The claws are so important that giant anteaters walk with the claws curled inward, effectively protecting the tips from constant wear against the ground.
The same claws can also be used defensively if an anteater is threatened.
Pangolin
Pangolins are specialized ant and termite eaters. Smithsonian material describes them locating insect nests by smell and digging into them with sharp claws before inserting the long tongue.
Powerful foreclaws are therefore central to the pangolin feeding system: without opening the nest, the tongue could not reach the insects inside.
Aardvark
Aardvarks have heavily muscled legs and strong shovel-shaped claws. They use them to dig deep burrows and break into very hard termite mounds.
Aardvarks are among the most impressive mammalian excavators. Their burrows are also ecologically important because many other animals later use abandoned aardvark shelters.
Armadillo
Armadillos have long front claws for digging and foraging. They use them to excavate soil, expose insects and open termite nests or decaying wood.
San Diego Zoo notes that the giant armadillo has especially large claws, while nine-banded armadillos commonly dig into the ground while searching for food.
Echidna
Echidnas are highly efficient diggers. Their strong front feet and claws can tear into soil and termite mounds, while the short legs generate substantial digging force.
San Diego Zoo also notes an unusually long claw on the second hind toe, which the echidna can use during grooming.
Meerkat
Meerkats have long, curved foreclaws that help them dig through dry soil while searching for insects, scorpions and other small prey. The same digging equipment is useful when enlarging burrows or rapidly creating shelter.
The claws are non-retractable, which makes sense for an animal that repeatedly scrapes and excavates soil.
Reptiles With Claws
Komodo Dragon
Komodo dragons have long claws on powerful limbs. The claws assist with traction and digging, and young Komodo dragons also spend considerable time in trees.
San Diego Zoo notes that adults may scratch shallow burrows for shelter. Their claws are therefore useful for more than prey encounters.
Crocodile
Crocodilians have clawed toes, but the claws are not their main weapons for capturing prey. The jaws perform that role.
The claws are more useful for terrestrial traction, moving over banks and digging. Females of many crocodilian species also use their limbs and feet while preparing or covering nest sites.
Other Mammals With Useful Claws
Rabbit
Rabbits have strong claws on the digits that improve traction and help dig burrows or shallow scrapes. In wild rabbits, digging is especially important for creating underground shelter and nesting spaces.
The claws are much less dramatic than those of a bear or anteater, but they are a good example of how ordinary-looking claws can be essential to daily survival.
Which Animal Has the Strongest Claws?
There is no universally accepted scientific ranking of “strongest claws.” Strength can mean several different things:
largest claw size
greatest gripping force
best ability to dig hard soil
greatest resistance to bending
most effective prey restraint
A harpy eagle has enormous talons for its body size, but an aardvark can excavate soil in a way an eagle cannot. A giant anteater can rip open termite mounds, while a jaguar benefits from a completely different retractable gripping system.
It is therefore more accurate to compare claw function than to declare one animal the absolute winner.
Which Animals Have Retractable Claws?
True cats are the best-known animals with retractable claws. In most felids, the claws are held away from the ground when not needed and extended for gripping, climbing or defense.
Cheetahs are the important exception. Their claw sheaths are reduced and most of the claws remain exposed, improving traction while running.
“Retractable” also should not be interpreted as meaning the claw disappears completely inside the paw. It is more accurate to say the terminal digit is held in a retracted position that keeps much of the claw off the ground.
Why Do Burrowing Animals Have Such Large Claws?
Digging requires moving compact material repeatedly. A narrow, delicate claw would wear quickly or move too little soil, so many fossorial mammals have enlarged forefeet, strong limb muscles and broad or curved claws.
The same basic principle appears independently in very different animals:
moles use shovel-like forefeet
aardvarks use powerful digging claws
armadillos excavate soil and insect nests
anteaters tear into termite structures
pangolins open ant and termite nests
echidnas dig for shelter and food
This is an example of similar functional problems producing similar adaptations in unrelated animals.
Do All Mammals Have Claws?
No. Mammalian digits have evolved into several different structures. Primates often have flat nails rather than claws, while hoofed mammals such as horses, deer and cattle have hooves.
Even within one animal, different digits can be specialized. Koalas, for example, have unusual hand and foot anatomy combining gripping digits, claws and a grooming structure.
Frequently Asked Questions
What animals have claws?
Examples include cats, bears, eagles, owls, cassowaries, iguanas, koalas, sloths, moles, anteaters, pangolins, aardvarks, armadillos, echidnas, meerkats, Komodo dragons, crocodiles, rabbits and bats.
What animals have sharp claws?
Big cats, raptors, cassowaries, anteaters and many climbing animals have especially sharp claws. Sharpness serves different purposes, including gripping prey, defense, climbing and tearing into nests.
Which mammals have claws?
Many mammals do, including cats, bears, koalas, sloths, moles, anteaters, pangolins, aardvarks, armadillos, echidnas, rabbits and bats.
Are talons the same as claws?
Talons are a specialized form of claw, usually referring to the sharply curved claws of birds of prey such as eagles, hawks and owls.
Do cheetahs have retractable claws?
Only partly. Cheetahs can retract their claws to some degree, but most of the claws remain exposed because the protective sheaths are reduced. This improves traction during high-speed running.
Which animal has the largest talons?
Harpy eagles are famous for exceptionally large talons. San Diego Zoo reports rear talons of about 5 inches (13 cm).
What animals use claws for digging?
Moles, aardvarks, anteaters, pangolins, armadillos, echidnas, meerkats and rabbits are all good examples of animals that use claws to excavate soil or open insect nests.
Do reptiles have claws?
Many reptiles do. Iguanas use claws for climbing, Komodo dragons use them for traction and digging, and crocodilians have clawed toes used mainly during movement on land and digging rather than as primary prey-killing weapons.
Official and Scientific Sources
Final Takeaway
Animals with claws have turned the same basic keratin structure into remarkably different tools. Jaguars grip prey, cheetahs gain running traction, harpy eagles seize animals with talons, cassowaries use a long inner claw defensively, iguanas and koalas climb, while moles, anteaters, pangolins, aardvarks, armadillos and echidnas dig. Looking at the shape and function of a claw often reveals exactly how an animal survives in its environment.
