Abstract: | Free-floating coelomocytes in the tentacular coelomic cavity of the sipunculan Thysanocardia nigra Ikeda, 1904, were studied using light interference contrast microscopy and scanning and transmission electron microscopy. The following coelomocyte types were distinguished: hemerythrocytes, amoebocytes, and two morphological types of granular cells. No clusters of specialized cells that had been reported to occur in the trunk coelom of Th. nigra were found in the tentacular coelom. The corresponding types of coelomocytes from the tentacular and trunk coelomic cavities were shown to differ in size. These two coeloms are completely separated in sipunculans. |
