需要看醫生不要碰很少致命，但如果有人碰了或吃了牠，要去看醫生。

皮膚裡有毒吃：肉有毒（碰或吃會中毒），不是有毒液

對人的危險: 嚴重如果有人碰了或吃了牠，要去看醫生。死亡案例非常罕見。

The Japanese fire-bellied newt is a small amphibian with a dark back and a bright red belly. It lives only in Japan, in ponds, streams, forests and grasslands. Its body contains a strong poison that helps protect it from predators.1

有毒還是有毒液？有毒液的動物會用咬或螫把毒液注入身體。有毒的動物則是碰到或吃下去會有害。這種動物是有毒的（碰或吃會中毒）。

在陸地上, 粗略估計

牠吃什麼？

Juveniles eat soil-dwelling springtails and mites. Adults eat many kinds of insects, including dragonfly and damselfly larvae, flies, bees, wasps, ants and beetles, as well as frog tadpoles and the eggs of their own kind. Some adults also eat carrion.1

怎麼認出牠

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

常被誤認為： 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

毒素力量

皮膚裡有毒

牠的皮膚有毒。碰、舔或吃牠都很危險。

牠的毒素有什麼作用？

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

牠對人有多危險？

對人的危險: 嚴重如果有人碰了或吃了牠，要去看醫生。死亡案例非常罕見。

牠害怕時會做什麼？

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牠

如果有人碰了牠：把手徹底洗乾淨，不要碰眼睛或嘴巴。如果小孩或寵物舔了或吃了牠：打給毒物諮詢中心或打緊急電話。

一定要先打緊急電話（112、000、911）。這是一般急救指引，不是醫療建議。急救基本知識

注意安全

絕對不要碰、抓或捉弄野生動物，就算是很小的動物，就算牠看起來在睡覺或已經死了也一樣。
給牠空間。如果遇到了，保持冷靜，慢慢往後退，讓牠自己離開。
如果你碰了或吃了牠：不要揉眼睛或摸嘴巴，把手洗乾淨，並且就醫。

牠不是想來抓你。牠的毒只是為了不讓別的動物吃掉牠。更多安全知識

值得知道

小知識

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
