TETRODON, in Ichthyology, a genus of the Branchi- 
ostegi order of fishes, according to the arrangement of 
Gmelin; the characters of which are, that the jaws are long, 
divided at the tip ; the branchiae or gills have a linear aper¬ 
ture ; the body is roughened beneath, and the ventral fins 
are wanting. The fishes of this genus, like the Chiodon, 
have the power of inflating their bodies at pleasure, by 
means of an internal membrane, and during this time the 
small spines of the sides and abdomen rise so as to be a 
defence against their enemies. They live principally on 
crustaceous and testaceous animals. Gmelin enumerates 
thirteen species. 
1. Tentrodon sceleratus, or the noxious tetrodon.—Tetra¬ 
gonal, with very large head; length two feet or more.— 
Found in the American and Pacific oceans, and considered 
as highly noxious, producing, when eaten, very severe 
symptoms. 
2. Tetrodon testudineus, or tortoise-shell tetrodon.—Ab¬ 
domen plane, smooth, and back with white curved sutures; 
length two feet; colour rufous-brown above, marked by nu¬ 
merous round pale blue spots; beneath blueish or ash-coloured, 
beautifully varied by longitudinal brown streaks; fins and 
tail bright, ferruginous; the whole abdomen is furnished 
with numerous small spines, w'hich, when the animal is un¬ 
disturbed, are imbedded in corresponding cavities in the skin, 
but elevated, when the fish is alarmed and disturbs its body. 
—Found in the Indian seas. 
3. Tetrodon lagocephalus, or hare tetrodon.—Abdomen 
aculeated; smooth body, and prominent shoulders; length 
twelve inches; thick in front; hinder parts tapering suddenly 
towards Ihe tail; colour above yellowish-brown, beneath 
whiteish with a silvery cast; across the back marked with 
short, black, or dark-brown bars, and over the sides with 
many, scattered, round, blackish spots; sides and abdomen 
beset with radiated spines; fins small, and tail slightly 
rounded.—Found in the Indian and American seas; and 
straying into northern latitudes, are taken about the British 
coasts. This fish has the power of inflating the abdomen to 
a large size; and derives its name from the resemblance of 
its head to that of a hare. 
4. Tetrodon lineatus.—With brow'n and pale bands; 
length ten or twelve inches, square shape; and when in¬ 
flated, like the last, body beset with small spines; colour 
grey on the abdomen, with longitudinal, deep brown 
streaks; fins and tail as in the last species.—Found in the 
Indian and American seas, and also in the river Nile. 
5. Tetrodon electricus.—With red, green, and white 
spots; above brown, and beneath sea-green; yellow at 
the sides, and green fins; length seven or eight inches; eyes 
large, with red circles.—Found, in the Indian and American 
seas, among coral rocks; arid v’hen touched with the hand, 
affecting it with an electric or galvanic shock. 
6. Tetrodon ocellatus.—Ocellated on the shoulder-band; 
length six or eight inches; thick, ovate shape, contracting 
towards the tail; colour deep green above, paler on the 
sides and abdomen, which are whiteish ; across the middle 
of the back, as far as each pectoral fin, a broad black 
crescent, edged with yellow; dorsal fin situated on a round 
black spot with yellow edges; lateral line from beneath the 
eyes to the tail, which is small and roundish; uuder parts 
beset with many spines.—Found in the Indian seas and 
adjoining rivers, particularly those of China and Japan ; 
very poisonous in its nature, and it is prohibited to be 
eaten under very severe penalties by the emperor of Japan. 
7. Tetrodon Irevigafus, or smooth tetrodon.—With the 
abdomen aculeated in front; a large species; blueish above, 
with two white stripes on each side; under parts white; 
from the mouth to the end of the pectoral fins aculeated ; 
the other parts being smooth.—Found in the American 
seas. 
8. Tetrodon hispidus.—Entirely hispid, with bristly pa 
pillee; length two feet; shape, when inflated, like that of tetro¬ 
don lagocephalus; colour whiteish ; upper parts marked across
