Life cycle and mating behavior
Könsmognad | Reproduktion | Lek | Eggs | Fecundity | Larvae
This is a hermaphrotic species. Egg masses are composed of 29 egg capsules, each one containing up to 721 eggs, and are retained beneath the female shell. Only a few of the eggs develop and the others serve as nutritional eggs (Ref. 87801). It displays poecilogonony as its reproductive strategy (Ref. 99837).
