Berthella or Berthellina from Turkey

July 31, 2003
From: Ferda Buyukbaykal


Hello Bill,
I took a new nudibranch in Ayvalik recently. [July 2003 - Aegean Sea coast, Turkey]. It was 5-8 metres deep, sandy/stone bottom and size 3-4 cm.
I think it may be Berthella aurantiaca or Berthellina edwardsi. Which is correct.?

Dear Ferda,
I am afraid these animals are not easy to identify just by looking at their external features. Although some species have distinctive colour patterns, ther are a group of species which range in colour from translucent white, through yellow to orange and red which are impossible to distinguish externally. The size of the internal shell is useful in distinguishing species of Berthella and Berthellina but other features of the anatomy are required to determine which actual species you are looking at. This makes ecological studies and studies on living animals very difficult, because the only way to identify them is to kill them.

Have a look at Lucas Cervera's message for further discussion. I have put your message on the Berthellina edwardsii page but I really wouldn't know what it is
Best wishes,
Bill Rudman
