摘要：In this paper we examined the histology of three commercially valuable species of precious corals ( Paracorallium japonicum , Corallium elatius, and C. konojoi ) from the Ryukyu Archipelago. In order to observe their inner structure, samples were thin sectioned and examined with a digital light microscope. Colonies of C. konojoi had thicker coenenchyme and larger autozooids than those of C. elatius and P. japonicum . The sclerites of the three species tended to be concentrated in the outer layers of coenenchyme. The gastric cavities of autozooids of all three species were found to be relatively empty. Some symbiotic polychates were observed in the axis of P. japonicum . As well, a zoanthid ( Corallizoanthus tsukaharai ) was often observed living on the coenenchyme surface of P. japonicum . It is hoped our observations will provide a good foundation of future study of Japanese Coralliidae corals.
