gastropod. Gastropod - Reproduction, Life Cycles: The fertilized egg of gastropods hatches into a free-swimming form (trochophore larva). In some species, the swimming veliger stage persists for weeks or even months. Land gastropods exhibit internal fertilization. Egg production is correlated with the degree of care given to the eggs or young. Gastropods, a mollusk class including slugs and snails, represent an extraordinarily diverse and ecologically significant group of organisms featuring the …
