Lehmann's poison frog

Oophaga lehmanni

名字的由來： It is named after Colombian conservation biologist Federico Carlos Lehmann.1

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。

箭毒蛙、蟾蜍和蠑螈

皮膚裡有毒吃：昆蟲有毒（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。

Lehmann's poison frog is a small, brightly marked frog that lives only in a small part of western Colombia. Its skin produces strong toxins, and its bright colours warn predators to leave it alone. It is critically endangered, so it matters for conservation as well as for safety.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）。

分布在

Endemic to western Colombia, in Valle del Cauca and Chocó departments, on the slopes of the Cordillera Occidental1

南美洲

It lives in submontane tropical rainforest, mostly on the forest floor and in low vegetation. Occasionally it is found in low shrubs and trees. It lives at heights of 600 to 1,200 metres.1

長度

3,1 cm 到 3,6 cm (1,2 in 到 1,4 in)1

最高速度

大約 3,7 km/h（2,3 mph）

牠吃什麼？

It is active during the day and mainly eats small insects it finds on the forest floor and in low vegetation. Tadpoles are fed unfertilised eggs by their parents.1

怎麼認出牠

Black or dark brown background with two bright, broad bands of colour round the body1
Coloured bands on the arms and legs, and on the belly1
Red, orange or yellow colour forms; each frog has its own unique pattern1
Males have silver-tipped toes1
Adults measure 31 to 36 mm from snout to vent1

常被誤認為： The harlequin poison frog (Oophaga histrionicus) looks very similar and can interbreed with it. Scientists still debate whether Lehmann's poison frog is a separate species. The main difference is that Lehmann's frog lacks histrionicotoxins, a type of toxin found in the harlequin frog. Males also have calls that differ between northern and southern populations.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？

It is not venomous. Its skin produces toxins, including alkaloids such as pumiliotoxins, that can be very poisonous. Frogs bred in captivity are not poisonous, because their diet lacks the chemicals needed to make the toxins.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。

The skin toxins can be very poisonous to predators, and some native tribes of Colombia used them to coat their darts. Frogs in captivity are not poisonous.1

牠害怕時會做什麼？

Its bright, vivid colours act as a warning to predators that it is inedible.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

In the wild, this frog is toxic, but frogs kept in captivity lose their toxicity because the toxins come from their diet.1

Tadpoles in the same pool may eat each other, so the male carries them to separate water pools.1

The male is the one who guards the eggs and carries the tadpoles on his back for two to four weeks.1

Its skin toxins are being studied for possible medicinal uses.1

Its bright colours are a warning, a strategy called aposematism.1

破解迷思

迷思： Lehmann's poison frog is always poisonous.

真相： Wild frogs are toxic, but frogs bred in captivity are not, because their diet lacks the chemicals needed to make the poison.1

學名: Oophaga lehmanni
類群: 箭毒蛙、蟾蜍和蠑螈
