Abstract

The article focuses on research papers related to hermaphroditism in viviparous ophiurids. The statement of researcher Wyville Thomson that the eggs and embroys of Ophiacantha vivipara Ljungman species are found lying free in the body cavity in the interbranchial spaces is, evidently, due to the fact that the bursae of Ophiurids were unknown at that time. Amphiura magellanica Ljungman is hermaphroditic. The arrangement of the gonads is quite different from that known to occur in Amphipholis squamata.
