它吃什么？

怎样认出它

The skin on its upper body is dark brown, approaching black, and covered in wartlike bumps.1
The underbelly and underside of the tail are bright red with black spots.1
Young juveniles have creamy coloured bellies instead of red, though most larger juveniles show some red.1
Males have flatter, wider tails and more red on the belly than females.1
Adults are 8 to 15 cm long.1

常被误认为： The German zoologist Heinrich Boie, who first described it in 1826, said he would have mistaken it for the smooth newt if he had not known it came from Japan.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 newt is not venomous: it does not bite or sting with venom. Its body contains high levels of tetrodotoxin, a neurotoxin, which is a poison that attacks the nerves. The newt gets most of this poison from its diet.1

它对人有多危险？

对人的危险: 严重如果有人碰了或吃了它，要去看医生。死亡非常罕见。

它害怕时会做什么？

Newts on smaller islands use the unken reflex, where they expose their bright red belly to startle or deter a predator. Newts on the mainland use different antipredator behaviour.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

事实

The newt's body contains tetrodotoxin, a poison that it mostly takes in from the food it eats.1

Newts can regrow missing body parts, and this ability has been studied by scientists.1

Wild individuals as old as 23 years have been found.1

Males and females both produce peptide pheromones, chemical signals that attract the opposite sex when they are ready to mate.1

The larvae hatch as swimming, gilled young and lose their gills and fins at five to six months, when they become juveniles that live on land.1
