Abstract

This study presents the first record of a jellyfish of the genus Drymonema from the Istanbul coast of the Sea of Marmara, Turkey, in February 2020. While exceedingly rare in the second half of the 20^th Century in the Mediterranean Basin, a specimen of the genus Drymonema (D. dalmatinum) has been recorded in the Gulf of İzmir and Foça (Turkey), but it has never been recorded as far into the Sea of Marmara. A role of citizen science in terms of spotting such rare species is highlighted.
