The New Intertidal Record of Goniobranchus annulatus (Eliot, 1904) (Chromodorididae) from Mersin Bay, Northeastern Mediterranean, Turkey

Hasan Deniz Akbora*, Deniz Ayas


One individual of Goniobranchus annulatus (Eliot, 1904), which is known as a tropical species, was found at the intertidal zone among the rocks near the Taşucu Bay. It was 3 cm in length and remarkable with its bright colors. After it was photographed and measured, the specimen was released back to the sea. This Heterobranchs are widely distributed in the Indian Ocean and is also being found in the Red Sea. It was first listed as “casual” alien species in CIESM in 2005, but today, it is established in the Levantine Basin.
