The fingernails is known to be as durable as a bird's beak The bird's beak and our fingernails are made out of the same exact substance. It is actually made out of protein called keratin that forms plates called rhamphotheca. How the beak of a bird can tear or cut things can also be done by the human fingernails. The same as our nails, the beak is constantly growing at an average of 1-3 inches per year. 3. The big toes has two bones and everything else have three The bones on the fingers and toes are called the phalanges. There are two bones in the big toe, and three in each of the other toes.
