I thought you might be interested in a couple of shots of Costasiella sp. 1 which Valda Fraser finds on a regular basis in the intertidal rockpools at Pumula, KwaZulu Natal, South Africa. We found two 'groups' of them (11 and 15) in different parts of the pool at 2pm on 18 December 2001 on low growing filamentous algae. Sizes: Upper Photo: 11 mm, Lower Photo: 8 mm. As you can see the cerata are quite a bit darker than the specimens found in SE Sulawesi, Indonesia but I think they are the same species.
What do you reckon?

All the best

Valda recently told me you were visiting South Africa. I'm glad you obviously had a successful trip. Valda has recently snt me a photo of this species so I'll post both messages together. It certainly looks very similar to Costasiella sp. 1 which would suggest this species has a wide distribution throughout the Indo-West Pacific, with records in the Forum from South Africa to Guam.
