Descripción breve
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 14; Radios blandos dorsales (total) : 12 - 13; Espinas anales: 2; Radios blandos anales: 12 - 13; Vértebra: 26. This species is characterized by the following: D XIV, 12-13; A II, 12-13; pectoral fin rays 19-20; 3 spiniform caudal fin rays; 16-17 tubed lateral line scales; gill rakers 5-7 + 19-20 = 25-27; white spots about a pupil size posteriorly, 1 at rear base of dorsal fin, another at the rear base of anal fin, and the third at mid base of caudal fin (these 3 spots usually fading after death, but may be visible as a pale area on preserved specimen) (Ref. 75861).
Body shape (shape guide): short and / or deep; Cross section: compressed.
Life history characteristics for the family specify that this group is oviparous, with distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205).
