The platypus is among nature's most unlikely animals. In fact, the first scientists to examine a specimen believed they were the victims of a hoax.
The platypus is best described as a hodgepodge of more familiar species: the duck, beaver, and otter.
Male platypus are also venomous. They have sharp stingers on the heels of their rear feet and can use them to deliver a strong toxic blow to any foe.
