Devil reef crab
The devil reef crab is a brightly patterned crab that lives on coral reefs across the Indo-Pacific, from East Africa to Hawaii. It is one of the most dangerous crabs in the world to eat, because its flesh and shell contain strong nerve poisons.1

毒素力量
只有被吃下去時才有害。
牠的毒素有什麼作用?
This animal is poisonous, not venomous, so it harms people when eaten rather than through a bite or sting. Its shell and meat contain tetrodotoxin and saxitoxin, which are neurotoxins (poisons that attack the nerves). They are absorbed through the gut and interfere with the sodium channels in nerve cells.1
牠對人有多危險?
對人的危險: 致命世界上最危險的動物之一。Poisoning from this crab can be fatal. In the Philippines, 50% of intoxication cases are reported to be fatal, and 12 people died on Negros Island in the 1980s. In Timor-Leste, one man died within hours of eating it, and in February 2021 two children in Cagayan died after eating crab their father had caught.1
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
Both the shell and the meat contain dangerous neurotoxins, so the crab is not safe to eat in any part.1
Some specimens have been found to contain more than 3000 MU of saxitoxin per gram, a lethal amount for humans.1
The toxins are the same kind of compound that makes pufferfish poisonous.1
The Philippines reports this crab as the most poisonous crab in its waters.1
