Abstract
    Thirteen adult individuals of a small octopus species of the Octopus aegina complex, 7 males and 6 females, were caught by trawl on bottoms ranging from 60 to 70 m of depth off the southern coast of Turkey, close to Mersin. This species (which is similar to O. kagoshimensis) was never before recorded in the Mediterranean. Further to the West on the southern Turkish coast (Gulf of Bodrum), a single individual of a pelagic squid of the genus Octopoteuthis was captured. The tentative identification as O. megaptera is based on the body shape and the presence and position of two caudal mantle photophores ; this is the first record of this species in the Mediterranean. These observations are discussed with regard to questions of species identification and possible recent species range extensions due to immigration from the Atlantic, or from the Red Sea (Lessepsian migration).
