Description synthétique Clés d'identification | Morphologie | Morphométrie

Rayons mous dorsaux (Total) : 10 - 12; Épines anales: 0; Rayons mous anaux: 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).

Estimates based on models

Preferred temperature (Ref. 115969): 14.8 - 26.8, mean 21.1 (based on 524 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01995 (0.00906 - 0.04395), b=3.01 (2.83 - 3.19), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.1 ±0.27 se; based on food items.

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (42 of 100).
