Pufferfish, locally known as fugu, fetch up to thousands of dollars for a kilogram in Japan, the reason being its incredibly poisonous character, thrilling the patrons with a brush of death. Chefs in the country undergo extensive training before they can pass as “fugu chefs,” for they should know how to carefully get rid of the poisonous parts that could be fatal.

Recently, the fishermen have been observing an anomalously higher number of hybrid pufferfish, a trend scientists blame on climate change, writes Popular Mechanics.

Warmer waters are driving pufferfish to cooler north, where its sibling species are interbreeding, spawning mutant hybrids that are as poisonous as an average fugu but not readily distinguishable, thus increasing the chances of accidental poisoning, notes Reuters.
