Dear Jacinto,

I am not an expert on nudirbanchs from your part of the world but I think this is Thordisa filix. It is normally thought of as Mediterranean but I see that Cervera et al (2006) record it from Galicia, on the Atlantic coast. Species of Thordisa have taepring retractile papillae over their mantle. Looking at your photos I am pretty sure the papillae are retracted. Then again I could be wrong, so let's wait for some words from local experts.

Best wishes,
