Puffer Fish, the most beautiful ornamental fish feeding and keeping in aquarium, Fugu , Bogeo fish

The majority of the pufferfish's species are toxic and some are among the most poisonous vertebrates in the world. In certain species, the internal organs, such as the liver, and sometimes the skin, contain tetrodotoxin, and are highly toxic to most animals when eaten; nevertheless, the meat of some species is considered a delicacy in Japan ( fugu), Korea (bogeo), and China (hétún) when prepared by specially trained chefs who know which part is safe to eat and in what quantity. Other pufferfish species with nontoxic flesh, such as the northern puffer, Sphoeroides maculatus, of Chesapeake Bay,[2] are considered a delicacy elsewhere.
