On some planktonic Anthozoan larvae in the Adriatic

Abstract

       This report intends to supplement earlier descriptions of Anthozoan larvae collected from the Adriatic Sea. A planula, the cnidom of which is identical to that in adult specimens of the genus Corynactis is described. Some aspects of morphology and development are compared in Dianthea nobilis and Synarachnactis bournei larvae. The morphology of an actiniarian and a scleractinian planual is treated.

      The terminology for adult specimens is used from STEPHENSON (1928) and CARLGREN (1949) and the nematocyst nomenclature follows those of WEILL (1934) and CARLGREN (1940, 1945).
