Actinopterygii (ray-finned fishes) > Tetraodontiformes
(Puffers and filefishes) > Triodontidae
Etymology: Triodon: Greek, tres, tria = three + Greek, odous = teeth (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 50 - 300 m (Ref. 4419). Tropical
Indo-West Pacific: East Africa to the Philippines, north to Japan, south to Australia and New Caledonia. Recently reported from Tonga (Ref. 53797).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 54.0 cm TL male/unsexed; (Ref. 4419)
soft rays: 9 - 10. Body yellowish-brown; belly flap white except for a yellow area around a black blotch (Ref. 4419). The 2.0 cm recruit differs from the adult in the structure of its viscera, most strikingly by the presence of the very large distended stomach, lacking in the adult (Ref. 54815).
Rare species (Ref. 4419).
