Mimic poison frog

Ranitomeya imitator

名字的由來： The species name imitator refers to the frog's habit of copying the colour patterns of other poison frogs.1

無害對人無害。不用擔心。

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: 輕微跟蜜蜂螫差不多或更輕微。對人基本上無害。

The mimic poison frog is a small, brightly coloured frog from the rainforests of north-central eastern Peru. It is one of the best known dart frogs, and it is special because different populations copy the colours of other poison frogs. Scientists have studied it closely for its unusual family life.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）。

It lives in primary and old-growth secondary rainforests, between 200 and 1200 metres above sea level. Each male is territorial and usually works from one good plant that it retreats to.1

牠吃什麼？

It eats ants, mites and other small invertebrates, including flies, beetles and springtails.1

怎麼認出牠

Its colour depends on its population. The striped morph has stripes, the spotted morph is mainly blue-green (sometimes yellow), the banded morph has bands, and the varadero morph is a separate form.1
Each colour morph copies a different, closely related poison frog that lives in the same area.1
It is active twice a day, once early in the day and again later on.1

常被誤認為： The striped morph closely resembles the striped Ranitomeya variabilis in colour. The two species differ in family life: this frog provides biparental care and is monogamous, while R. variabilis provides only paternal care and is polygamous.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？

Its skin contains pumiliotoxin B, a potent toxin. Because the frog is small, it can only secrete a limited amount of poison. Frogs kept in captivity do not make the toxin, so it probably comes from toxic insects and other invertebrates eaten in the wild.1

牠對人有多危險？

對人的危險: 輕微跟蜜蜂螫差不多或更輕微。對人基本上無害。

Its toxicity is mild compared with other poison dart frogs. Its small size limits how much poison it can secrete.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

Mimic 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)

Mimic poison frog 大約 3,4 km/h (2,1 mph)

一個正在走路的人 大約 5 km/h (3,1 mph)

值得知道

小知識

It is the first amphibian shown to be monogamous, meaning a pair stays together.1

After the eggs hatch, the female feeds the tadpoles with unfertilised eggs, which are a source of food.1

It evolved biparental care independently, so both parents look after the young.1

Male frogs attack other males that enter their territory.1

給毒液專家

學名: Ranitomeya imitator
類群: 箭毒蛙、蟾蜍和蠑螈
家人: Dendrobatidae2
排序: Anura
各大洲: 南美洲
寶寶: After mating, the female lays fertilised eggs on a plant, and the male guards them and carries each tadpole to a small pool of water in a plant. One study recorded 1 to 4 tadpoles per mated pair reaching the breeding pool.1
