背棘 (总数) : 71 - 77; 背的软条 (总数) : 0; 臀棘: 0; 臀鳍软条: 46 - 50. Caudal small and rounded, directed upward; pectorals as minute flaps (Ref. 6885). Greenish black with several dusky white bars on posterior part of body, 2 dark bands diverging back from each eye, each band double with a paler center (Ref. 6885).
尾部的小而且圆的, 方向朝上; 如细小的鳃盖胸鳍.(参考文献 6885) 呈绿色的在身体后部， 2个深色条纹分开来自每个眼的背面上黑色的有一些暗色的白色横带, 每个条纹加倍具有一个较灰白的中心.(参考文献 6885)
Facultative air-breathing (Ref. 126274); Found in rocky areas, from intertidal to 18 m depth, mostly on exposed coast (Ref. 2850). May remain out of water under rocks or seaweed (Ref. 31184). Feed mainly on algae (Ref. 6885). Oviparous, eggs are laid in several clumps or masses which are guarded by the male (Ref. 58332). Breathe air (Ref. 31184) and can stay out of water for 17-23 hours if kept moist (Ref. 51276).
发现于岩石区了, 从潮间带到 18 公尺深, 大部份在裸露的海岸上.(参考文献 2850) 可以停留在岩石或海草下面离开水面.(参考文献 31184) 主要吃藻类。 (参考文献 6885) 呼吸空气 (参考文献 31184) 而且能离开水面停留 1723 小时的如果保持潮湿.(参考文献 51276)
