Korte beschrijving Determinatiesleutels | Morfologie | Morfometrie

Dorsale zachte stralen (totaal) : 10 - 12; Anale stekels: 0; Anale zachte stralen: 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).
