The
platypus (
Ornithorhynchus anatinus), sometimes referred to as the
duck-billed platypus, is a
semiaquatic egg-laying
mammalendemic to
eastern Australia, including
Tasmania. Together with the four species of
echidna, it is one of the five
extant species of
monotremes, the only mammals that lay
eggs instead of giving birth. The animal is the sole living representative of its
family (
Ornithorhynchidae) and
genus (
Ornithorhynchus), though a number of
related species have been found in the fossil record. The first preserved platypus body was thought to have been a fake, made of several animals sewn together,
[3] when it was first looked at by scientists in 1799.

The unusual appearance of this egg-laying,
duck-billed,
beaver-tailed,
otter-footed mammal baffled European naturalists when they first encountered it, with some considering it an elaborate hoax. It is one of the few species of
venomous mammals: the male platypus has a
spur on the hind foot that delivers a
venom capable of causing severe pain to humans. The unique features of the platypus make it an important subject in the study of evolutionary biology and a recognisable and iconic symbol of
Australia; it has appeared as a mascot at national events and is featured on the
reverse of its
20-cent coin. The platypus is the animal emblem of the state of
New South Wales.

Until the early 20th century, it was hunted for its fur, but it is now protected throughout its range. Although captive breeding programs have had only limited success and the platypus is vulnerable to the effects of pollution, it is not under any immediate th
