Some nuclear vacuoles were observed inside and along the outer part of the nucleus and double-membrane structures were observed between the nuclear membrane and plasma membrane. The sperm sleeve consisted of four independent parts and had more than four mitochondria. Along the sperm tail there were wing-like lateral fins.展开更多
文摘The spermatozoon ultrastructure of left-eye flounder, Paralichthys olivaceus, was observed by electronic microscopy, and shown to consist of head, midpiece and tail. Some nuclear vacuoles were observed inside and along the outer part of the nucleus and double-membrane structures were observed between the nuclear membrane and plasma membrane. The sperm sleeve consisted of four independent parts and had more than four mitochondria. Along the sperm tail there were wing-like lateral fins.
