Peptide and protein pheromones in molluscs.
Pheromones have been implicated in the control of a number of behaviors in molluscs, but few peptide pheromones have been characterized in these animals. Peptide pheromones include: (1) a family of water-borne peptide pheromonal attractants (attractins) in the gastropod Aplysia that are released during egg laying and attract other Aplysia to form egg-laying and mating aggregations; (2) a tetrapeptide (ILME) in the cephalopod Sepia that elutes from egg masses and is thought to be involved in the transport of oocytes in the genital tract during egg laying; and (3) a Sepia sperm-attracting peptide (SepSAP; PIDPGVamide) that is released from oocytes during egg laying to facilitate external fertilization.
