Berthellina edwardsii : confirmation from Cerbere

From: Marina Poddubetskaia

Dear Bill and Lucas,
Last year there was a discussion on the Forum to know if the animals from Cerbere are Berthella aurantiaca or Berthellina edwardsii. This year I saw 3 animals like this in Cerbere and all of them had undetectable shell. So, you were absolutely right ! These guys are Berthellina edwardsii.

Date: July 08, 2003
Location: Cerbere, France, Mediterranean coast
Site: Les 3 moines
Depth: 16m
Size: 20mm

Dear Marina,
I think the point we were making is that it's not possible to identify these orange, yellow or whitish animals by colour alone. It's possible that species of Berthella and Berthellina, with this colour range, both occur at Cerbere. So even though its nice to be told I am right, it's possible that last years' animal was Berthella and this years' was a Berthellina. It is indeed a pity they donb't all have distinctive colour patterns like Berthella ocellata.
Best wishes,
Bill Rudman
