3. (Zool.)
(a) Any plectognath fish which inflates its body, as the
species of {Tetrodon} and {Diodon} of the family
{Tetraodontidae}; -- called also {blower},
{puff-fish}, {swellfish}, and {globefish}. They are
highly poisonous due to the presence of glands
containing a potent toxin, {tetrodotoxin}.
Nevertheless they are eaten as a delicacy in Japan,
being prepared by specially licensed chefs who remove
the poison glands.
(b) The common, or harbor, porpoise.

Toxin \Tox"in\, Toxine \Tox"ine\, n. [Gr. toxiko`n. See {Toxic}.
]
A poisonous product formed by an organism, such as a
pathogenic bacterium, a plant or an animal, usually having a
high molecular weight, often a protein or a polysaccharide,
but occasionally a low-molecular weight agent such as
{tetrodotoxin}.


blowfish \blow"fish\ n.
1. a fish eaten as a delicacy, especially in Japan. It is
highly dangerous because of a potent nerve poison
(tetrodotoxin) in its ovaries and liver. Chefs require
special training to learn how to remove the poisonous
parts, and in Japan they must be licensed.

Note: In Japan it is called {fugu}. Deaths due to ingestion
of the meat of this fish occur almost every year.

Syn: sea squab, puffer, puffer fish.
[WordNet 1.5 PJC]

2. any of numerous marine fishes of the family
{Tetraodontidae} whose elongated spiny body can inflate
itself with water or air to form a globe; several species
contain {tetrodotoxin}, a potent nerve poison; they are
closely related to spiny puffers.

Syn: puffer, globefish.
[WordNet 1.5 PJC]
