Aeolidiella glauca f rom Sweden

December 17, 2001
From: Mike Noren

The slug on the picture was collected at Tjärnö on the Swedish west coast late November. It's about 15-20mm long. Unfortunately I do not know for certain what it was collected from, or even what depth, although it probably came from a sample of red algae with abundant bryozoans, hydroids, sponges and ascidians, with some Alcyonium soft corals thrown in for good measure, collected at about 15 - 8m depth.

My best guess as to identity is Cuthona nana?

Hi Noren & Bill,
This is Aeolidiella glauca - note the big eyes, chunky appearance, rhinophore pigmentation, ceratal pigmentation, ceratal arrangement
