Taille / Poids / Âge
Maturité: 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).
Body shape (shape guide): fusiform / normal; Cross section: compressed.
Inhabits shallow waters, usually in schools near the bottom. Feeds mainly on small crustaceans, polychaetes and algae (Ref. 30573).
