"Ninja" frog(忍者蛙)
Take a close look at this frog. Isn't it different from every single frog you've ever seen? An American biologist discovered it living in the urban landscape of New York City. For a long time, it was thought the animal was a variety of leopard frog. However, this green creature covered with spots was noted as having a croak which was quite distinct from the "long snore" of the leopard frog. As a result, it has been properly defined as a new species of frog. Currently the scientists are studying the frog further to properly name it, but for now it has been nicknamed the "Ninja" frog.
