What is the Japanese delicacy that consists of the poisonous puffer fish with the poisonous parts (hopefully) removed?
Tetraodontidae predators, such as sharks, but it can kill humans. Larval pufferfish are chemically defended by the presence of TTX on the surface of skin, which causes predators to spit them out. Not all puffers are necessarily poisonous; the flesh of the northern puffer is not toxic (a level of poison can be found in its viscera) and it is considered a delicacy in North America. "Takifugu oblongus", for example, is a "fugu" puffer that is not poisonous, and toxin level varies wildly even in fish that are. A puffer's neurotoxin is not necessarily as toxic to other animals as it
