Pufferfish

Tetraodontidae is a family of marine and freshwater fishes in the order Tetraodontiformes. Members are commonly called pufferfishes and by many other common names. They are morphologically similar to porcupinefish; porcupinefish have large external spines, while Tetraodontidae species have thinner, hidden spines that become visible only when the fish inflate. The family name refers to the four teeth of the genus Tetraodon. The majority of pufferfish species are toxic — some contain the potent neurotoxin tetrodotoxin in internal organs and sometimes skin. Despite this, certain species' meat is consumed as a delicacy in parts of East Asia when prepared by trained chefs who know which parts and quantities are safe. Some species have nontoxic flesh and are eaten elsewhere. One species, Torquigener albomaculosus, is noted for males that build complex geometric sand nests to attract females.

The strongest linked planning options currently surface around destinations such as Koh Tao, Phuket, Dahab and countries such as Indonesia, Thailand, Egypt for divers building trips around pufferfish.
