Pleurobranchaea meckelii? from Turkey

March 2, 2004
From: Umut Tural

Dear Bill,
Another species from Mediterranean Sea. I guess,this is a Pleurobranchaea meckelii, it seems to be P. meckelii if you look at external body but considering your message in the Forum says that "there are number of species occurring in the Mediterranean, all look very similar externally & need to look at anatomy of these species able to identify it correctly". So my specimen might be something else, as according to your message we can't identify it from photos. I thought a photo would be adequate. I wish I could have fixed the animal & looked at its anatomy. Perhaps it is a new record from Turkey.

Many thanks in advance.
Best wishes
Umut Tural.

Dear Umut,
According to Marcus & Gosliner's (1984) revision there are a number of species in the western Atlantic, however as Lucas Cervera comments [#2267], this genus needs further study in your part of the world. I'm afraid that most species of Pleurobranchaea worldwide are very similar in colour - mottled brown - so we are very dependent on anatomical information. Thankfully not all opisthobranchs are so difficult to identify externally.
Best wishes
