It is bright yellow to yellow-orange with dark markings both on and between the tubercles, or bumps, on its back; and an oval body with seven gills. Its oral tentacles are ear-shaped (Ref. 312).
Occurs in low intertidal to subtidal zones with hard substrate. Feeds on sponges (Ref. 312), e.g., Halichondria sp. (Ref. 822). Also in Ref. 93916.
生命週期和交配行為
成熟度 | 繁殖 | 產卵場 | 卵 | 孕卵數 | 仔魚
Members of the order Nudibranchia are simultaneous hermaphrodites. Mating behavior: Both individuals darts their penis toward each other to induce one to act as a male and the other as the female. The victorious one to penetrate the body wall is the dominant male. Life cycle: Eggs are deposited on a substratum where they develop and hatch into (planktonic) vestigial veliger larval stage and further grow as adults.
