As soon as we write about curious animals – let me introduce the next evidence of narute’s sense of humor.
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 animal is best described as a hodgepodge of more familiar species: the duck (bill and webbed feet), beaver (tail), and otter (body and fur).
Webbed feet enable the platypus to swim well. Each hind foot of the male has a poison spur that can kill small animals and inflict painful wounds on larger ones. Crushing its food with the horny plates of the bill and mouth, the platypus each day eats about half its own weight in worms, insect larvae, mollusks, crustaceans, and vegetation, all consumed underwater.
The male Platypus has venomous ankle spurs which produce a cocktail of venom!!! This venom is not lethal to humans, but does produce excruciating pain; so intense that the victim may be incapacitated. 
And one mo fact about platypus, which confirm their leading position in the list of strange animals: platypus reproduction is unique. It is one of only two mammals (the echidna is the other) that lay eggs!
