簡短描述 型態特徵 | 形態測量圖

This species is distinguished from its congeners by the following characters: 2 tubercles between the eyes; projecting upper jaw distinct; tubercles in dorsal row 27-30, ventral row 27-30, upper lateral row 15-24 but the lower one usually absent; granules few or sparse on head and back in front of first dorsal; a few larger ones between upper lateral and dorsal rows of tubercles; chin barbel slightly compressed, half of eye diameter in length; D1 III-IV; sides with dark blotches and irregular dots (Ref. 59043).

生物學特性     字彙 (例如 epibenthic)

This species is rarely found in marine waters for it prefers salinity below 9 ppt. Occurs in still or slowly flowing water over muddy bottom at depths of around 0.5-10 m in summer and moves to deeper waters in winter. It lives for a about a year; spawns in April-October. Females lay eggs in two portions, sometimes more and die shortly after last release of eggs while the males die 3-4 weeks later. The males probably guard a clutch of eggs until hatching. Feeds on benthic invertebrates, mainly molluscs (Ref.59043).
