Claw vs. Nail — What's the Difference?
By Tayyaba Rehman & Fiza Rafique — Updated on April 29, 2024
Claws are sharp, curved appendages at the ends of the digits of many animals, used for hunting and climbing, whereas nails are flat, protective keratin plates covering the tips of fingers and toes in humans and some primates.

Key Differences
Claws are typically pointed and curved, serving as tools for gripping, climbing, or as weapons in predatory animals. Whereas nails are generally flat and more rounded, primarily providing structural support and protection to the tips of digits in humans and primates.
In terms of composition, claws are made of a hard protein called keratin and are often much thicker and stronger than nails. On the other hand, nails also consist of keratin but are thinner and serve as a protective cover rather than for active use in catching or defending.
Claws grow continuously and can be sharpened by wear or grooming. Whereas nails also grow continuously but require trimming and do not naturally sharpen.
Animals with claws often use them for hunting, such as cats using their retractable claws to catch prey. Whereas nails are not used for hunting but can be used for tasks requiring fine motor skills, like typing or picking up objects.
Claws are often adapted to an animal's environment or behavior, such as birds having claws for perching. On the other hand, human nails are not significantly adapted for environmental factors but can reflect health conditions or nutritional status.
