Descrição breve
Morfologia | Morfometria
Espinhos dorsais (total): 0; Raios dorsais moles (total): 112-118; Espinhos anais 0; Raios anais moles: 89 - 94. Snout rather blunt; eye diameter almost as long as snout; opercular spine strong and straight; hind margin of preopercle usually with 3 sharp spines; 1 median (broad) and a pair (larger and overlapping median one) of basibranchial tooth patches; pseudobranchial filaments 2 or 3; 7-15 developed rakers on anterior arch; lower 5-11 pectoral fin rays free and longer than upper ones; precaudal vertebrae 13-16 (Ref. 34024). No black fin rays; spines in supraorbital absent and on preopercle absent or weak (Ref. 34024).
Rare species (Ref. 34024). Reproductive strategy possibly similar to other members of this family featuring oviparity, with oval pelagic eggs floating in a gelatinous mass (Ref. 205).
