背棘 (总数) : 20 - 23; 背的软条 (总数) : 14 - 16; 臀棘: 2; 臀鳍软条: 24 - 27. Males uniform grey to black with red fins and a bluish white margin to the anal fin during the breeding season. Females mottled greenish grey with an indistinct broken dark band along the base of the dorsal fins. Distinguished from other triplefins by the flattened pointed head and snout, the short, square caudal peduncle, and by having three spines in the first dorsal fin and 14-16 spines in the second.
Body shape (shape guide): elongated.
雄性均匀的灰色在繁殖季节的时候黑色的有红色的鳍与一个蓝白色的边缘到臀鳍。 雌性有斑点的呈绿色的灰色有一个不明显的断掉深色条纹沿着背鳍的基底。 与平尖的头部与吻,短,正方形尾柄的其他三鳍鳚区分了, 与藉由在第一背鳍中有三个棘而且在第二个中有三个 14-16根棘。
Adults are commonly found in sheltered areas shallower than 5 m. Typical in shallow habitats in coastal mainland areas and seldom on offshore islands. Mainly found under rocks. They feed on a range of benthic invertebrates including ophiuroids, archaeogastropods, trichoptera and errant polychaetes (Ref. 84084). Eggs are hemispherical and covered with numerous sticky threads that anchor them in the algae on the nesting sites (Ref. 240). Larvae are planktonic which occur primarily in shallow, nearshore waters (Ref. 94114). They are caught by slurp guns and handnets (Ref. 84086).
发现于岩石之下了或在裂隙中。 可能夜行。
