Baron's mantella

Mantella baroni

名字的由來： It is named after Richard Baron, an English botanist and missionary to Madagascar who collected and studied the species.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。

Baron's mantella is a small, brightly coloured frog that lives only on the island of Madagascar. Its skin contains toxic chemicals that make it harmful to predators, and its bright colours warn them to stay away.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

在陸地上, 粗略估計

牠吃什麼？

It is a very active forager that mainly eats ants. It also eats beetles, spiders and mites, and it eats more large arthropods than any other Mantella species.1

怎麼認出牠

Has a light line above the eyes, called a rostral line.1
Hind limbs are orange with irregular black stripes, giving a tiger-like pattern.1
Front limbs range from light green to bright orange or yellow, with a large rounded flank blotch.1
Adults are 2.4 to 3.2 cm long, and females are slightly larger than males.1
Males call during the day, and it is an active hunter in daylight.1

常被誤認為： It is often confused with the painted mantella (Mantella madagascariensis), which has a similar look. The painted mantella has a sky-blue, horseshoe-shaped marking on its throat. Baron's mantella does not have the flashmarks on its lower hind limbs.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 does not inject venom. Its skin contains alkaloids, which are toxic chemicals it gets from eating mites. These make it harmful to predators that eat it, and they can cause sickness. The strength of the toxin varies over time and by location, and frogs in remote populations may be more potent.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 can vary, and careless handling is discouraged.1

牠害怕時會做什麼？

Its bright colours warn predators that eating it could be dangerous and cause sickness.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

Its toxicity comes from the mites it eats, so its poison depends on its diet.1

Mantella frogs look like poison dart frogs from Latin America, but they are only distant relatives. The likeness is an example of convergent evolution.1

Unlike most frogs, which are active at night, it hunts during the day.1

Its bright colours and its toxins are a warning system, a pattern called aposematism.1

Its family arrived on Madagascar an estimated 76 to 87 million years ago.1

It is one of the largest species in the Mantella genus, with only some Mantella viridis individuals reaching a similar size.1

破解迷思

迷思： Baron's mantella is the same as the painted mantella, and is sometimes called a painted mantella.

真相： The two are distinct species. They look alike, but the painted mantella has a sky-blue throat marking that Baron's mantella lacks.1
