Taille / Poids / Âge
Maturity: Lm ?  range ? - ? cm
Max length : 12.0 cm TL mâle / non sexé; (Ref. 30573); common length : 8.0 cm TL mâle / non sexé; (Ref. 3424)
Épines dorsales (Total) : 8; Rayons mous dorsaux (Total) : 16; Épines anales: 3; Rayons mous anaux: 14. This species of the Equulites elongatus group is distinguished by the following set of characters: eye diameter 82-137% postorbital head length; distance from pelvic-fin insertion to center of anus 35-50% of the distance from pelvic-fin insertion to anal-fin origin; scales above lateral line 8-13, below 12-19; dorsolateral body with large dark blotches rarely forming ring marks (0-2) and a few dark spots (0-5) that are smaller than a half of pupil diameter; the tips of neural and hemal spines of fourth preural centrum is less expanding, distal expansion ratios of neural and hemal spines of the fourth preural centrum 2.1-3.9. Colour of the head and ventrolateral body almost uniformly silvery white; snout tip blackish; upper posterior margin of the operculum pale yellow; dorsolateral body silvery brown with scattered dark blotches; pectoral axil dark and pectoral fin pale yellow; black lines along the caudal-fin rays, the posterior margin of caudal fin dark while other fins are colourless (Ref. 120651).
Inhabits shallow waters, usually in schools near the bottom. Feeds mainly on small crustaceans, polychaetes and algae (Ref. 30573).
