Khimicheskaya morfologiya: triterpenovye glikozidy goloturii (Echinodermata, Holothuroidea)
The ultrastructure of spermatozoa of Cucumaria japonica and a congeneric morphologically similar deep-sea species was studied. The spermatozoa of both C. japonica and C. conicospermium are similar to those of other holothurians: the acrosome is composed of an acrosomal granule and periacrosomal material; the centrioles lie at an acute angle to one another; and the proximal centriole is connected to the nuclear envelope by a flagellar rootlet. The spermatozoa of C. japonica differ from those of C. conicospermium in the shape of the head and the dimensions and position of the acrosome. In C. japonica, the acrosome is completely embedded in the nuclear fossa and measures 0.7 μm. In C. conicospermium, only one-third of the acrosome is embedded in the nuclear fossa; this acrosome measures 1.3 μm. A correlation between the structure of the sperm acrosome and that of the egg envelope is discussed.
