Dear Kevin,

This animal certainly has the digitiform rhinophores that Pseudotritonia antarctica is reported to have, but that species only has tubercles around the mantle edge. I am pretty sure your animal is the related Charcotia granulosa,  which has tubercles scattered all over its back.

Have you any idea what the orange branching colony the animal is crawling on is? from the orange contents in the digestive gland it may well be the animal's food. If so it would be a useful addition to outkowledge of this antarctic species.

Best wishes,
Bill Rudman
