Let’s see:
Ancient, egg-laying, poisonous, web-footed, beaver-tailed and duck-billed.
It’s got to be the Platypus, and it’s got to be one of the strangest animals on earth. Here’s a bit of a closer look.
The bizarre appearance of this egg-laying, venomous, duck-billed, beaver-tailed, otter-footed mammal baffled European naturalists when they first encountered it, with some considering it an elaborate fraud.

British scientists’ initial hunch was that the attributes were a hoax.
George Shaw, who produced the first description of the animal in the Naturalist’s Miscellany in 1799, stated it was impossible not to entertain doubts as to its genuine nature, and Robert Knox believed—because it arrived in England via the Indian Ocean—that it might have been created by Chinese sailors.
It was thought somebody had sewn a duck’s beak onto the body of a beaver-like animal. Shaw used a pair of scissors to check for stitches.
Native only to Eastern Australia, this endemic species checks all sorts of boxes for oddities.
It is one of the few venomous mammals, the male platypus having a spur on the hind foot that delivers a venom capable of causing severe pain to humans.

The newly hatched young are vulnerable, blind, and hairless, and are fed by the mother’s milk.
Although possessing mammary glands, the platypus lacks teats. Instead, milk is released through pores in the skin. There are grooves on her abdomen in which the milk pools, allowing the young to lap it up. (Um…whoa!)

Poisonous Mammal?
While both male and female platypuses are born with ankle spurs, only the male has spurs which produce a cocktail of venom, composed largely of defensin-like proteins (DLPs), three of which are unique to the platypus.
The defensin proteins are produced by the immune system of the platypus. Although powerful enough to kill smaller animals such as dogs, the venom is not lethal to humans, but is so excruciating that the victim may be incapacitated.

The Platypus is one of only a handful of monotremes. Monotremes are the only mammals known to have a sense of electroreception: they locate their prey in part by detecting electric fields generated by muscular contractions.
The platypus’ electroreception is the most sensitive of any monotreme.
Existing only in Australia and Tasmania, the Platypus has risen in stature to become a mascot at sporting events, and even lives on Australian currency.
While not currently endangered, the species is considered near-threatened, as habitat destruction negatively affects its population.
We love nature’s extreme oddities, like the Platypus, which has fascinated humans ever since it was discovered.
