背的软条 (总数) : 7. Black spot on each side of the caudal peduncle. Males with a second similar spot behind each pectoral fin (Ref. 35388); eyes situated laterally; fully scaled; possess functioning suckers; caudal fins slightly notched (Ref. 92840).
在尾梗的两边上的黑色的斑点。 雄性有第二个在每个胸鳍后面的相似斑点。 (参考文献 35388)

生物学特性     字汇 (例如 epibenthic)

Suprabenthic (Ref. 92840). Found inshore in groups around over-grown structures and among Laminaria or Zostera beds. Adults feed on small crustaceans (copepods, amphipods, mysids) and chaetognaths (Ref. 4696). Eggs are about 1 mm long, pear-shaped, and adhere to seagrass or weeds; hatch in 10 days (Ref. 4696). Pelagic larvae hatch at 2.5 mm length (Ref. 35388).

发现于岸边了成群生长过度的结构周围与在 Laminaria 或 Zostera 床之中。 吃小型甲壳动物 (桡脚类的动物，片脚类动物, 糠虾) 与毛颚类动物。 (参考文献 4696) 卵是大约 1 mm 长, 珠状的, 而且黏附在海草或杂草; 大洋性仔鱼在 2.5 mm 长度孵化。 (参考文献 35388)
