Abstract

The morphology and taxonomic values of the sperm in male Chlamys (Swiftopecten) swiftii were investigated by transmission electron microscope observations. The morphologies and ultrastructures of the sperm nucleus and the acrosome of this species are the vase type and long cone shape, respectively. Spermatozoa are approximately $45-50{\mu}m$ long including a sperm nucleus (approximately $2.60{\mu}m$ long), an acrosome (about $0.63{\mu}m$ long), and a tail flagellum (approximately $44-47{\mu}m$ in long). The axoneme of the sperm tail shows a 9+2 structure. In this study, the right and left basal rings in the acrosomal vesicle of this species show electron opaque part (region), and also the anterior apex part of the acrosomal vesicle shows electron opaque part (region). These characteristics of the acrosomal vesicle were found in Pectinidae and other several families in subclass Pteriomorphia. The number of mitochondria in the midpiece of the sperm of this species are four, as one of common characteristics appear in most species in Pectinidae in subclass Pteriomorphia. In addition, the satellite fibres are found near the distal centriole of this species, as have been reported in other species of Pectinidae in subclass Pteriomorphia. Accordingly, structutral characteristics which are found in the acrosomal vesicle, four mitochondria in the sperm midpiece and the appearance of the satellite fibers near the distal centriole of C. (S.) swiftii in Pectinidae (subclass Pteriomorphia), can be employed for phylogenetic and taxonomic analyses as taxonomic key or a significant tool.
