Life cycle and mating behavior
Γεννητική Ωρίμανση | Αναπαραγωγή | Γεννοβολία | Eggs | Γονιμότητα | Larvae
Sexes are separate but are seldom conspicuously different externally, simultaneous hermaphrodites yet self-fertilization is prevented due to various morphological, physiological, or behavioral mechanisms; generally, marine gastropods shed their eggs (Ref. 87872).
