摘要：

We performed histological studies on trophic and reproductive systems of colonial interna in Sacculina polygenea, a parasite of the coastal crab Hemigrapsus sanguineus. The trophic system that performs functions of absorption, accumulation, and transportation of nutrients from the hemolymph of the host comprises the trophic epithelium of distal canals and transporting trunks. The reproductive system of interna consist of nuclei (early stages of development of the primordia of externae) and the primordia of externae in later stages of development. It has been shown that during morphogenesis of the nucleus two primordia arise, a primordium of the externa itself and a primordium of its trophic system. In the primordium of the ovary, we found oogonia; early oocytes and vitellogenic oocytes were found in the ovaries of the late primordia of the externae. The damaging effects of the interna on the ovaries and testes of the crab host are discussed. Thus, we have found numerous elements of reproductive and trophic systems in the colonial interna of S. polygenea. The term individual is proposed to be used for the externa in rhizocephalan barnacles with its trophic system. © MAIK "Nauka/Interperiodica" 2002.
