Turtle!

Turtles are actually one of the oldest and most primitive reptiles in the world, having evolved millions of years ago!

There are over 300 species of turtles, which will be why you see some with flippers, claws, legs, and all sorts!

A turtle's shell is actually its ribcage! It is made up of 60 bones and the shell plates are made of the same stuff as human fingernails!
