Upper Right; Lower Left: AM C124694, 12mm long alive, 8 May 1974, paratype. Lower Right: AM C124693, 10mm long alive, 16 Aug. 1973, paratype.
Rhinophores with relatively long scattered papillae on posterior side. The cerata are long and cylindrical, not as flattened as Spurilla major. The body and foot are translucent white with pinkish-orange viscera showing thrugh the body wall. There is a pigmented white patch on the head, the white being most intense around the edge, and a diamond-shaped whitish patch behind the rhinophores. In some specimens there are scattered white patches down the dorsal surface of the body. No sign of zooxanthellae in digestive gland. Grows to about 20mm in length. Similar in shape and colour to Spurilla chromosoma but differs in ceratal arrangement and shape of the rhinophores, papillate in S. salaamica, lamellate in S. chromosoma.

It certainly seems that this species has a wide Indo-West Pacific distribution. Like Tanzanian animals there seems to be no sign of branching digestive gland ducts in the body wall.

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.

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.

While identifying Jun Imamoto's photos of this species from Japan I realised I had not posted photos from Tanzania. Spurilla salaamica was always found intertidally on the piles supporting the sewer pipe, on the north side of the Harbour entrance, Dar es Salaam, Tanzania.
