Bats use their curved claws on their wings to hold on to things such as trees. It helps them to stay still while not flying. Bats use the claws on their feet also to hold on to trees upside down but they also use them to hunt. They use their sonar detection to find the prey, fly to it, and grapple it between their clawed feet. This is how bats use their curved claws.
Penguins have webbed feet that terminate in several claw-like appendages. However, in the 'clawing' sense of claws, penguins don't use the ends of their webbed feet as claws for feeding purposes, but do use them to secure purchase on ice and on hilly areas where they breed.So, 'yes' if by claws you mean 'look like claws'. (Scientists use the term claw to describe the terminus of the webbed foot of a penguin.)So, 'no' if by claws you mean 'uses claws to catch food, like a cat or a raven'.
They are called talons.
Cockroaches use their front claws to gather food. The front claws are located near the cockroach mouth. The prey is fed directly from the claw to their mouth.
Owls use thier feet which have claws to grasp thier prey like mice.
A tamandua is a species of anteater from South America. It uses its front claws and forearms to protect itself by backing up against a rock or tree and grabbing its opponent.
They hold it with their claws, and put it into their mouths with their front legs.
Gophers dig tunnels with their front claws and teeth, while kicking the loose soil back with their hind feet. The gophers use this soil to plug their tunnels and keep predators out.
Both types of monotremes - the platypus and the echidna - are unusual, but perhaps the platypus is considered the most unusual of all. The platypus has a bill equipped with electroreceptors which it uses to find its food. It must live on land but find its food in the water. It has retractable webbing on its feet so that it can still use its sharp claws to dig.
Platypuses use their feet for more than two tasks, but the main tasks, apart from walking, are swimming and burrowing. Platypuses have webbed feet with a retracting webbed membrane which can expose the claws, enabling the platypus to effectively dig burrows. Its claws are used for digging burrows into riverbanks for shelter, and the webbing membrane retracts for that purpose, but spreads between its toes when it needs to swim - which it needs to do to get its food.
Cheetahs cannot retract their claws as they are necessary for fast running. They also use their dew claws to trip prey so that they can grab them by the neck for the kill. Of course, having non-retractable claws limits the cheetah's climbing ability.
