Maturity: Lm ?  range ? - ? cm Max length : 5.0 cm TL male/unsexed; (Ref. 844)

Biology     Glossary (e.g. epibenthic)

Assumed maximum length from Ref. 844. Feeds on the blue sponge Haliclona sp. (Ref. 844). 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 (Ref. 833).
