Demersal cephalopods from the Sea of Marmara with remarks on some ecological characteristics

Abstract

        Eight species of demersal cephalopods were collected by means of otter-trawl, beam-trawl and dredge from the Sea of Marmara between 1990 and 1996. These included Sepia elegans, Sepia orbignyana, Rondeletiola minor, Sepietta oweniana, Alloteuthis media, Loligo vulgaris, Eledone cirrhosa and Eledone cf. moschata. While Sepietta oweniana and Loligo vulgaris were recorded in the waters where the salinity is always over 25x10^-3, the remaining species were also found in brackish water.
