Аннотация:Ultrastructure of envelopes of ovulated oocytes and spermatozoon ultrastructure are described in
two closely related species of the family Mullidae, Upeneus tragula and U. cf. margarethae. Oocyte envelope
is represented by the thin zona radiata and weakly expressed chorion. The spermatozoon is characterized by
the presence of elongated head with a pointed bend in its apical part and nuclear fossa reaching approximately
90% of the head length. The centriolar complex and basal part of the flagellum are located inside of the
nuclear fossa.
