簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 20 - 23; 背的軟條 (總數) : 14 - 16; 臀棘: 2; 臀鰭軟條: 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.
雄性均勻的灰色在繁殖季節的時候黑色的有紅色的鰭與一個藍白色的邊緣到臀鰭。 雌性有斑點的呈綠色的灰色有一個不明顯的斷掉深色條紋沿著背鰭的基底。 與平尖的頭部與吻，短，正方形尾柄的其他三鰭鳚區分了, 與藉由在第一背鰭中有三個棘而且在第二個中有三個 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).
發現於岩石之下了或在裂隙中。 可能夜行。
