This review compares historical data sets (1967-68, 1974-1976, 1993-1995)to the most recent data (2003-2004)on the composition, abundance and vertical migration of cnidarians of the deep southern Adriatic. 18 species of medusae are typical open-ocean holoplanktonic species and 6 of these were either always or frequent found in samples, namely Rhabdon singulare, Aglaura hemistoma, Persa incolorata, Rhopalonema velatum, Sminthea eurygaster, and Solmissus albescens. The most common calycohore siphonophores are Lensia subtilis, L. meteori, Eudoxoides spiralis, Sphaesonectes gracilis, and S. irregularis, followed by Hippopodius hippopus, Vogtia penthacantha, Lensia comoidea, L. fowleri, Chelophyes appendiculata, Kephyes ovata, and Bassia bassensis. Some difference in presence and abundance betwen historical and recent data are noted. |
