The enigmatic mating behaviour and reproduction of a simultaneous hermaphrodite, the nudibranch Aeolidiella glauca (Gastropoda, Opisthobranchia)



The enigmatic mating behaviour and reproduction of a simultaneous hermaphrodite, the nudibranch Aeolidiella glauca (Gastropoda, Opisthobranchia)



Canadian Journal of Zoology 80(2): 0-70



Hermaphroditic mating behavior is poorly investigated and understood, especially in internally fertilized species. This study describes the mating behaviour and reproduction of the simultaneous hermaphrodite Aeolidiella glauca. Unlike other nudibranchs, A. glauca was found to transfer sperm via external spermatophores that were attached to the partner's back. Despite an elaborate courtship, the actual spermatophore transfer, which always involved two animals only, was of short duration. In most matings (88%) spermatophores were reciprocally exchanged. Shortly after transfer the ventral spermatophore cover dissolved and some sperm gathered on the epidermis. A few even penetrated epidermal cells, occasionally causing considerable damage. Most sperm, however, migrated along the body surface towards the gonopore. Migrating sperm needed 4-5 h to reach and enter the gonopore, but sperm consumption by the recipient sometimes delayed this process. Almost 30% of spermatophores fell off soon after transfer, but spermatophores from reciprocal matings and those placed in certain positions stayed on for longer. Slugs mated readily with different partners and egg production was very high. However, sperm from a single mating may not suffice to fertilize all eggs. Aeolidiella glauca's unique mating behaviour may offer ample opportunities for both sperm competition and alternative sperm utilization.
