Spurilla salaamica from Japan

From: Jun Imamoto

Dear Bill,
We discovered the pleasures of tide pools when I went to look for sea slugs on the beach near the my house. (By car, at the time of about 40 minutes.) Various sea slugs were there. Then, we met with a difficult question. Are these sea slugs Berghia japonica? These were discovered under stones, near each other.
Please, give me advice.

Date: 6 Oct 2001
Place: Manazuru, Sagami Bay, Japan. Depth: 0.3m (Intertidal).
Upper Right: about 20-23mm long.
Lower Left: about 8-9mm long.
Lower Right: about 6-7mm long.
Water temperature: 26C degrees.
Best Regards,
Jun Imamoto

Dear Jun,
This is an interesting find. I am sure that at least two of the animals are the same as a species I found in East Africa and named Spurilla salaamica. I am not so sure of the photo at Lower Right. It looks like a species of Favorinus to me but the papillate rhinophores are unusual. It differs from the animals in your other two photos in both the shape and arrangement of the cerata and the arrangement of the papillae on the rhinophores. In this animal the papillae are all over the rhinophore club while in Spurilla salaamica they are only found on the posterior half of the club.
Best wishes,
Bill Rudman.
