Sea hares have annual life cycles (Ref. 126605). Common on tidal platforms of mixed sand and rock; actively crawling in tide pools at night and in crevices and under rocks during the day (Ref. 866). Grazes on various types of green algae (Ref. 844). Found in warm seas (Ref. 822). Known from depths of 0 to 20 m (Ref. 7727); from low intertidal to immediate subtidal on alga-covered reefs (Ref. 337). Ejecting ink as a predator deterrence and to send alarm signals to conspecifics, but not all spotted sea hares have ink (Ref. 84419). Ink components are based on the chemical properties of their diet (Ref. 84420). Ascorhynchus sp. found parasitic on the gills of this nudibranch (Ref. 121217).
