Abstract
With the help of scanning and transmission electron microscopy, the morphology of spermatozoa of Icelus spiniger and egg envelopes of I. spiniger and I. spatula has been studied. Spermatozoa have an elongated head flattened on one side, an insignificant centriolar fossa, and numerous mitochondria in the middle section. The axoneme has a structure described by the formula 9 + 2. The envelopes of oocytes of both species have a follicular membrane, chorion, and zona radiata.
