The spermatozoa of Platichthys stellatus is relatively simple cells composed of a
spherical head, a short midpiece, and a tail, as in most Pleuronectiformes. The ultrastructure is
characterized by the following features: a round nucleus with a deep nuclear fossa, the centriolar
complex located at a right angle to each other, a short midpiece, a tail with paired lateral ribbon and
no acrosome. However there are some minor morphological differences, including the appearance
and number of the mitochondria, the shape and size of the nuclear fossa and the structure of the
basal body. Especially the basal body structure consisting of a basal foot, a rootlet and nine alar
sheets structures varies considerably in different species. It can be used as indicator of relationships
in Pleuronectiformes because minute morphological differences might have functional and evolutionary
significance. In conclusion, the spermatozoa of P. stellatus show a certain structural homogeneity
and provide support for the concept that ultrastructural features of spermatozoa can be useful
in taxonomic studies of Pleuronectiformes.
