  • The mechanism of internal fertilization in vermetids has long remained obscure because these sessile gastropods are attached to the substrate throughout their adult life. In addition, in Serpulorbis jmbricatus spermatozoa production and egg laying occur in different seasons. In this study the following observations of the unique manner of sperm transfer in two Japanese species of Serpulorbis were made: The males produce spermatophores and expel them from the mantle cavity. A spermatophore… CONTINUE READING
