A resident intertidal species with homing behavior (Ref. 32612), found in sheltered areas and common in tide pools (Ref. 2850). In areas with rough surf, it occurs in higher, more sheltered places (Ref. 2850). Can leave tide pools when aquatic conditions become inhospitable (Ref. 31184). Shows a tendency to return to its home pool if displaced (Ref. 6885). Breathes air when out of water (Ref. 31184).
一個定居的潮間帶的種有歸巢的行為 (參考文獻 32612), 發現於掩蔽的區域與常見於潮池。 (參考文獻 2850) 在有粗糙的海浪的區域中,它更高地出現於中, 比較掩蔽的地方.(參考文獻 2850) 當水生的環境變成不適居留的時候，能離開潮池。 (參考文獻 31184) 顯示如果移置了，回到它的家水池的趨向.(參考文獻 6885) 呼吸空氣當離開水面.(參考文獻 31184)
