簡短描述 型態特徵 | 形態測量圖

背棘 (總數): 8; 背的軟條 (總數): 16; 臀棘 3; 臀鰭軟條: 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).
身體銀色而有斑點的綠色與深色的背面。 頭部沒有鱗片; 頰與胸部覆蓋著小鱗片了; 頸背的棘呈現; 伸長的嘴分向朝下.(參考文獻 2108)

生物學特性     字彙 (例如 epibenthic)

Inhabits shallow waters, usually in schools near the bottom. Feeds mainly on small crustaceans, polychaetes and algae (Ref. 30573).

棲息於淺水域,通常成群聚集近的底部。 (參考文獻 30573,48635) 主要吃小型甲殼動物,多毛類動物與藻類。 (參考文獻 30573)
