Yellow-banded poison dart frog
The yellow-banded poison dart frog is a small, brightly coloured frog from the northern part of South America. It lives in wet tropical rainforests, close to fresh water. Its bright warning colours show that its skin is toxic to eat or touch.1

怎麼認出牠
- Predominantly bright yellow, with varying numbers of broad black stripes or spots over the whole body1
- Some individuals are orange instead of yellow1
- Markings range from fine spots to thick, unbroken bands1
- Small, with an average adult length rarely above 4 cm1
- Active during the day and lives in small groups1
毒素力量
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, so it does not inject venom. Its skin secretes alkaloid toxins. Some of these are extremely potent neurotoxins, which attack the nerves, and they interfere with nerve impulses. This can lead to heart failure or fibrillation, which is an irregular heartbeat.1
牠對人有多危險?
對人的危險: 疼痛可能會非常痛,但幾乎從來不會很嚴重。牠害怕時會做什麼?
Its bright yellow and black colouring is aposematic, a warning to predators that it is unpalatable or toxic to eat.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

小知識
It is the only poison dart frog known to estivate, which means going into a dormant state, during dry spells.1
Its toxins come from the arthropods it eats, so the frog's poison depends on its diet.1
It can cope with lower humidity better than other species in its genus, although it still prefers humid conditions.1
It is easy to breed in captivity, which has helped lower prices in the pet trade.1
It is one of the largest species in its genus, Dendrobates.1
