Harlequin poison frog

Oophaga histrionica

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：昆蟲有毒（碰或吃會中毒），不是有毒液

The harlequin poison frog is a small, brightly marked frog that lives on the forest floor of western Colombia. Its skin carries strong toxins, so it is one of the poison dart frogs that should never be handled. It is now critically endangered because its rainforest home is being destroyed.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）。

怎麼認出牠

Background colour ranges from light to dark brown.1
Usually has a vivid, bright spot on its back.1
Small, with an average snout-to-vent length of about 3.3 cm.1
Active on the forest floor, feeding on the ground after sunrise and hiding under leaf litter or on fallen logs by 16:00.1

常被誤認為： Some frogs that were once classed as this species were separated into new species in 2018: Oophaga anchicayensis, Oophaga andresi and Oophaga solanensis.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 frog produces histrionicotoxins, which are cardiotoxins, meaning they affect the heart. These compounds act as potent blockers of nicotinic acetylcholine receptors, the sites that receive nerve signals at muscle and nerve junctions. They also affect sodium and potassium channels, though much less strongly.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 frog's toxins can be dangerous. Wild-caught frogs may be toxic and dangerous to handle, and they often have a much higher fatality rate in captivity.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

大約跟一根迴紋針一樣長可以在 97 秒內跑完 100 公尺（最快的人類需要 9.6 秒）

Harlequin poison frog 跟「你」比起來有多大？

牠有多快？

一隻陸龜 大約 0,3 km/h (0,19 mph)

Harlequin poison frog 大約 3,7 km/h (2,3 mph)

一個正在走路的人 大約 5 km/h (3,1 mph)

值得知道

小知識

The tadpoles cannot feed on their own. They are obligate egg-feeders and will starve without the unfertilised eggs their mother provides.1

A parent carries the tadpoles to tiny water pools, often found in the axil of a bromeliad plant, where they develop.1

Histrionicotoxins are hard to make in a lab. Synthesising them has been the subject of many different attempts.1

Harlequin poison frogs are among the most difficult poison dart frogs to raise in captivity.1

Adults are active on the ground during the day and retreat to refuge by mid-afternoon.1
