Biology     Glossary (e.g. epibenthic)

This nudibranch can cause severe indirect envenomation to humans when it comes in contact with skin. This is due to the venomous nematocysts that were ingested by the nudibranch as they prey on Physalia species (Ref. 125676).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

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.
