Eastern newt

Notophthalmus viridescens

只是会疼不要触摸会疼，但不会对你造成严重伤害。

皮肤里有毒吃：肉碰了或吃了有毒，不注射毒液

The eastern newt is a small amphibian that lives in eastern North America. Its bright orange young, called red efts, walk around on land in damp forests. The adults carry a strong poison in their skin, so they are best left alone.1

有毒还是有毒液？有毒液的动物通过咬或蜇注入毒液。有毒的动物是碰了或吃了会受害。这一种是碰了或吃了有害的。

首页

Eastern newts live in both coniferous and deciduous forests, and they need a moist environment with a temporary or permanent body of water. Adults stay in muddy ponds, lakes, swamps, ditches and quiet streams, while red efts may be seen in a forest after a rainstorm. They are also common aquarium pets, either collected from the wild or sold commercially.1

它吃什么？

As larvae they feed on small aquatic invertebrates. As adults and efts they eat insects, springtails, soil mites, snails, worms, small crustaceans, young amphibians and frog eggs, typically every two to three days.1

怎样认出它

Larvae are brown-green and have gills, and they live only in the pond where they hatched.1
Red efts, the land-dwelling juveniles, are bright orangish-red with darker red spots outlined in black. One newt can have as many as 21 spots.1
Adults are dull olive green on the back with a dull yellow belly, and they keep the black-rimmed red spots.1
Adults develop a larger, blade-like tail and slimy skin.1

常被误认为： Central newts, a subspecies, are brown or green with fine black dots all over the body and may have a row of red spots on each side. Their belly is yellow or orange and noticeably lighter than the rest of the body.1

毒力

皮肤里有毒

它的皮肤有毒。摸、舔或吃都很危险。

它的毒会造成什么？

The eastern newt is poisonous rather than venomous, so it does not bite or sting to deliver its toxin. Its skin contains tetrodotoxin, a neurotoxin, meaning it attacks the nerves. In predators it can cause muscle paralysis, skin irritation and even death, and it is also the strongest known emetic, meaning it causes vomiting.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。

Its skin toxin is harmful to predators, and the newt should not be handled with bare hands.1

它害怕时会做什么？

Its bright red colouring warns predators, and its skin releases toxins. Its ventral surface has poison glands, and it can swim quickly away from aquatic predators.1

如果有人碰了或吃了它

如果有人碰了它：好好洗手，不要碰眼睛或嘴巴。如果孩子或宠物舔了或吃了它：打电话给中毒急救中心或急救电话。

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。
如果你碰了或吃了它：不要揉眼睛或嘴巴，洗手并就医。

它不是冲着你来的。它的毒只是为了不被吃掉。更多安全知识

值得了解

事实

Newt larvae increase their toxin production when predators, such as dragonflies, are nearby.1

Eastern newts can regenerate lost limbs.1

A Belted Kingfisher was observed beating an eastern newt on a nest box 15 times before eating it.1

The eastern newt's bright red juvenile stage is called a red eft, and it may travel far from its pond.1

Only about 2% of larvae survive to reach the red eft stage.1

Some larvae have been found in the pitchers of the carnivorous plant Sarracenia purpurea.1
