The hairy frog (Trichobatrachus robustus) is no ordinary amphibian. So named because breeding males develop hair-like dermal papillae along their flanks and thighs, which scientists believe are intended to increase surface area, for the purpose of absorbing oxygen. But why are you wasting our time with this, you ask. This is not so unusual, you say! No. Indeed, it is not.
But have you ever heard of a frog that has the capacity to break its own bones in order to create extendable claws like those of a cat, protruding from the broken skin of its toes?
No, we thought not.
