The platypus is a semiaquatic mammal that lays eggs, and it has a duck-like bill and a beaver-like tail. It lives in eastern Australia, including Tasmania. It is special because it is one of the few venomous mammals.1

它吃什么？

The platypus digs in stream bottoms with its bill and uses electrolocation to detect the tiny electric currents made by the muscles of its prey. It has cheek pouches for storing food.1

怎样认出它

Short, dense, brown fur that is waterproof1
A soft, duck-like bill1
A wide, flat, furry tail, unlike the scaly tail of a beaver1
Short legs with webbing, most noticeably on the front feet1
Small eyes and ears that sit in a groove that closes underwater1

常被误认为： Early European naturalists were confused by the platypus and thought it was a fake, made by sewing a duck's beak onto a beaver-like body. Its tail looks like a beaver's, but it is furry rather than scaly.1

毒液之力

有毒的距

后腿上的尖距带着毒液。

它的毒液会造成什么？

Only the male platypus has venom, which it injects through a spur on each hind foot. The venom is powerful enough to cause extreme pain in humans. The affected limb then develops swelling, which starts at the wound and spreads.1

它对人有多危险？

对人的危险: 很疼可能真的很疼，但几乎从不严重。

The venom is extremely painful.1

如果它的毒距刺到你

把伤口洗干净并就医。

一定先拨打你的急救电话（112、000、911）。这里是一般急救指导，不是医疗建议。急救基础

注意安全

永远不要摸、抓或逗弄野生动物，即使是很小的，即使它看起来在睡觉或已经死了。
给它留出空间。如果遇到它，保持冷静，慢慢后退，让它走自己的路。
如果它腿上的毒距刺到你：保持冷静，保持不动，拨打你的急救电话（112、000、911）或尽快去医院。记住它长什么样，拍张照片会有帮助。

它不是冲着你来的。它用毒液捕猎或保护自己，而且它更愿意躲起来。更多安全知识

值得了解

事实

The platypus has about 40,000 electroreceptors in its bill, which detect electric signals from prey in murky water.1

Its fur is one of the most densely packed of any mammal, behind only otters. It also glows cyan and green under ultraviolet light.1

The platypus lacks a functional stomach, because it does not have the genes needed to make pepsin, a digestive enzyme.1

Adult platypuses have no teeth. They have heavily keratinised grinding pads instead, and young platypuses lose their teeth around the time they leave their burrow.1

Its average body temperature is about 32 °C, lower than the 37 °C typical of placental mammals.1

谣言粉碎机

谣言： The platypus is a hoax, made by sewing several animals together.

真相： The platypus is a real species. When the first scientists examined a preserved body in 1799, they doubted it, and George Shaw even used scissors to check for stitches.1
