A resident intertidal species with homing behavior (Ref. 32612) found in shallow rocky areas (Ref. 2850). Commonly found in tide pools, often in algae (Ref. 2850). Can leave tide pools when aquatic conditions become inhospitable (Ref. 31184). Breathes air when out of water (Ref. 31184).
一个定居的潮间带的种有归巢的行为 (参考文献 32612) 发现于水浅的岩石区。 (参考文献 2850) 普遍地栖息于潮池, 常见于藻类中。 (参考文献 2850) 当水生的环境变成不适居留的时候，能离开潮池。 (参考文献 31184) 呼吸空气当离开水面.(参考文献 31184)
