Melibe from Turkey

March 7, 2001
From: Peter H. van Bragt

Hello Bill,

This summer a friend of mine (Eddy Zandt) came back from a diving trip in the Mediterranean sea at Turkey. He made the enclosed photographs of a large and swimming seaslug. After some searching I ended up with Melibe fimbriata as a possible determination of the species name.
Can you confirm this???

Thanks and with best regards

Dear Peter,
Thompson & Crampton (1986) and Moosleitner (1986) record this species from the Ionian Sea, Greece. It is considered to have entered the Mediterranean from the Indian Ocean through the Suez Canal as the genus Melibe does not occur naturally in the Mediterranean. Thompson & Crampton identified their animals with Melibe fimbriata but as I have suggested above, Melibe viridis is probably the earliest name for this species.

It grows to quite a large size, Moosleitner's largest animal being more than 30cm long. From Eddy Zandt's photo, it looks like his specimen was also quite large.
