Espinhos dorsais (total): 8; Raios dorsais moles (total): 9; Espinhos anais 2; Raios anais moles: 9. Greenish grey, with dark vertical bar from origin of spiny dorsal to just in front of anus; scattered spots on body, head and 1st dorsal membrane; pelvic fins dark (Ref. 4329, 48635).
Restricted to coastal waters, forming small aggregations among mangroves, rocks, debris, or piers of shallow sheltered shorelines. Feeds at night (early evening and just before day break), primarily on planktonic crustaceans. Courtship and spawning occur fortnightly (shortly before new moons and full moons). Eggs are incubated by the male for about 8 days. Larval phase pelagic. Sexual maturity is attained at 7 cm by males and at 6 cm by females (Ref. 1602).
Life cycle and mating behavior
Maturidade | Reprodução | Desova | Ovos | Fecundidade | Larvas
Courtship and spawning occur on a semi-lunar cycle, shortly before full and new moons (Ref. 37816). Distinct pairing during courtship and spawning (Ref. 205). Are mouthbrooders (Ref. 240). Males incubate up to 12,000 eggs for a period of about 8 days (Ref. 37816). After the pelagic larval phase, juveniles settle and grow at a rate of 3 to 6 mm per month (Ref. 37816).
