日本河豚因气候变暖杂交变种毒性增强

Techub News 消息，rising sea temperatures are pushing pufferfish species together, spawning hybrids that even specialist chefs cannot safely prepare. Fugu – the collective Japanese name for several species of edible pufferfish – is prized as much for the danger surrounding its preparation as for its subtle flavour. Many species contain tetrodotoxin, a powerful neurotoxin with no known antidote that can cause paralysis, respiratory failure and death. Since 1958, anyone wishing to prepare pufferfish for public consumption has had to obtain a licence first, a process that takes at least two years and defeats roughly two-thirds of those who attempt it.（SCMP）
