Tetraodontiformes (Puffers and filefishes) >
Triodontidae (Three-toothed puffer)
Etymology: Triodon: Greek, tres, tria = three + Greek, odous = teeth (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Ecology
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)
Dorsal soft rays (total): 10 - 12; Anal spines: 0; Anal soft rays: 9 - 10. This species is easily distinguished from superficially similar tetraodontid and diodontid larvae or early juveniles of comparable size by the following characters: separate premaxillae in conjunction with fused dentaries; with multicuspid spinoid scales; a jet-black mark in front of the soft dorsal fin; the developing pelvis, which is visible through the distended skin of the belly; with a number of procurrent caudal fin rays. It differs from the adult in having a huge head that measures 45% SL (vs. 28.5-32.7% in adult), absence of the characteristic dewlap with the conspicuous lateral ocellus, and structures of the scales and nostrils (Ref. 54815). Body yellowish-brown; belly flap white except for a yellow area around a black blotch (Ref. 4419).
Rare species (Ref. 4419).
