Headed frog
African frog gets its name from the side skin structure similar to male hair. Hair is used to increase the rate of the frog to absorb oxygen, because males spent a long time to keep the eggs. Another impressive fact of this frog is that they have claws that can be pulled out which is made of bone (as lawam keratin). However, to remove the claw, the frogs have to break a bone nodule in advance.
