Arminina

It must be said that we know little about the Arminina, other than that they have specially shaped rhinophores and no external gills.

Quite a busy Nudibranch, which feeds on Sea Pens out on the sand. We've seen them in the day, although they are said to be nocturnal. Previously known as A. semperi

Only one sighting so far; thank you Gabriele.

A very small Arminian, frequently spotted amongst the Octocoral species.

An one-off sighting in 2022 at Koh Ma by ex Chaloklum Diving divemaster Patrick.
