Some records of the superfamily Plumularioidea L. Agassiz, 1862 (Cnidaria, Hydrozoa) from the Bay of Biscay

Abstract

Nineteen hydrozoan species belonging to four families Aglaopheniidae (9 spp.), Halopteridae (3 spp.), Kirchenpaueriidae (1 sp.) and Plumulariidae (6 spp.) were collected from 61 stations along the Cantabrian coast and the continental shelf and slope (depth range littoral-1347 m). A systematic account of the superfamily Plumularioidea and comments on the distribution and depth range of the species are given. The presence of A. lophocarpa in the Bay of Biscay is confirmed. Cladocarpus multiseptatus (Bale, 1915), so far recorded only from the Mediterranean and the Indo-Pacific is recorded for the first time in Atlantic waters.
