The Spike-Nosed Tree Frog
Also called the long-nosed tree frog, the spike-nosed tree frog has a funny projection on the end of its nose. Only the males of the species have this distinctive trait. Experts also refer to this cool animal as the Pinocchio frog for apparent reasons. The protuberance points upward when the male calls and deflates when the male is resting. However, the size of this spike plays no role when females choose males to mate with. Scientists believe that this spike only helps the frogs differentiate themselves from other species of frogs that live in the forests.
