Short description Claves de identificación | Morfología | Morfometría

Espinas dorsales (total) : 14 - 16; Radios blandos dorsales (total) : 12 - 13; Espinas anales: 3; Radios blandos anales: 8 - 10. Diagnosis: upper profile of head strongly convex; lower pharyngeal bone about as long as broad, and with anterior lamella shorter than toothed area (Ref. 53405). 10 or fewer rakers on lower limb of first arch; unpaired fins not predominantly red-brown; mouth terminal; 29-30 scales on lateral line; outer row teeth robust (Ref. 81260). Dorsal fin with 14-16 spines and 12-13 soft rays (total rays 27-29) (Ref. 53405, 81260). Anal fin with 3 spines and 8-10 soft rays; caudal fin weakly covered with scales at base or entirely membranous (Ref. 81260). Caudal without spots, grey on upper lobe, yellow on lower; large vertical stripes weakly pronounced on flanks; flank scales with a blackish mark at base (Ref. 53405, 81260). No bifurcated dark vertical bars on flanks; dorsal and anal without orange-red upper margin (Ref. 53405). Length of caudal peduncle 10.5-12.9% of standard length (Ref. 81260).

Very tolerant of elevated salinities, found in pure seawater, even reproduction in these highly saline environments is possible (Ref. 52307). Feeds on shrimps, bivalves, plankton (Ref. 28587), detritus (Ref. 28587, 52307), higher plants, algae, aufwuchs and small crustaceans (Ref. 52307). Oviparous (Ref. 205). Very prolific, spawning up to every 3 weeks (Ref. 52307). Pair bonding, open (Ref. 52307) substrate brooder/spawner (Ref. 52307, 81260) with both parents guarding the brood (Ref. 52307).

Life cycle and mating behavior Maturities | Reproducción | Spawnings | Egg(s) | Fecundities | Larva

Oviparous (Ref. 205). Subtrate guarding of eggs as a form of parental care is done by both male and female (Ref. 50828).
