Sakuraeolis enosimensis? from Japan

April 6, 2002
From: Nishina Masayoshi

Dear Bill,
I think this is Sakuraeolis enosimensis (Baba, 1930)

AS you say in your description:
"There is a white tip to the smooth tapered rhinophores and a white line along the dorsal side of the long tapering oral tentacles. There is also a dorsal white line along the tip of the posterior foot. "

This animal has those white lines clearly.

Photographed by M. Fumiko
Data: Omijima Island, Yamaguchi pref.
Length 115mm

Best Regards,

Dear Nishina,
This is an interesting animal. Although it has a white line on the oral tentacles, like in Sakuraeolis enosimensis, it also has a white line on the rhinophores, the cerata, and a dorsal median white line down the body, none of which are found in that species. Another unusual feature is that it seems to be crawling on a soft coral, which is not the usual food of a Sakuraeolis. It may just be passing by, but the other possibility is that this is a species of Phyllodesmium, which usually feed on soft corals. The third point of interest is the length of this animal - 115mm is quite large for an aeolid, and the largest aeolids are often species of Phyllodesmium.

Without knowing something of its anatomy I can't say any more. Perhaps someone will recognise it for us.
Best wishes,
Bill Rudman
