Climbing mantella

Mantella laevigata

名字的由來： The scientific name Mantella laevigata places it in the genus Mantella; the species name refers to its smooth skin, from the Latin laevigata meaning smooth.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 climbing mantella is a small, brightly coloured frog that lives in the lowland rainforests of northeast Madagascar. It is a poison frog, so its skin holds chemicals that can harm predators. It is special because it is one of the few frogs whose parents care for their tadpoles by feeding them eggs.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）。

首頁

Lives in lowland rainforests and bamboo groves, spending time in trees and bamboo but staying near water. It is found in several protected areas, including Masoala National Park and Marojejy National Park. It needs humidity of 80% to 100%.1

長度

2,4 cm 到 3 cm (0,9 in 到 1,2 in)1

體重

1,2 g 到 2 g (0 oz 到 0,1 oz)1

最高速度

在陸地上, 粗略估計

牠吃什麼？

Eats ants, insect larvae, mites and other small insects found in leaf litter, taking whatever is most available. Ants make up about 84% of its diet in the dry season but only 35% in the wet season, when its diet is more varied.1

怎麼認出牠

Adults are 24–30 mm long and weigh 1.2–2.0 g1
Front of the back is bright yellow or pale green1
Arms, legs, belly and rear are black, with blue spots on the limbs1
Eyes are completely black1
Has discs at the tips of its fingers and toes, and the toes are webbed1

常被誤認為： M. betsileo, M. viridis and M. expectata look similar but are differently coloured. They often have blue spots on the throat rather than the limbs, and they have a faint line along the upper lip, which the climbing mantella lacks.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？

This frog is poisonous rather than venomous. Its skin glands contain lipophilic alkaloids, the chemicals that make up its poison, which it gets from the arthropods it eats. Researchers have found 41 different potent alkaloids in its skin. Captive frogs lose their toxicity over time.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。

牠害怕時會做什麼？

Its bright colours warn predators that its skin is toxic.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 tadpoles eat only the eggs of their own species, and the parents feed them unfertilized eggs.1

Males defend territories of about 2 square metres and fight by wrestling, chasing and leaping, sometimes for over 1.5 hours.1

Female frogs choose a mate based on the quality of the male's well, not on his call.1

The climbing mantella is the only member of the Mantella genus that breeds in water-filled wells in trees, tree holes or broken bamboo stalks.1

Its chemical defence has developed in a similar way to that of the dart frogs of Dendrobatidae, although the two families are only distantly related.1
