Aeolids from East China Sea

April 23, 2005
From: QinJi


Dear Bill,
I found these very small nudis last sunday in the East China Sea. They would have been about 12-15 mm long. They were found on a hydroid colony. Would I be correct in identifying them as Eubranchidae or Sakuraeolis enosimensis?

These species haven't found in China before.

Locality: 'fishpond', Xiamen, China, East China Sea. Depth: 2 metres. Length: 10 mm.17 April 2005. on hydroids. Photographer: QinJi

Dear AJi,
I think you have two species here. The upper two photos seem to be a species of Cuthona. The shape of the head, with the oral tentacles arising some distance in from the edge, is rather characteristic of Cuthona.  Also the anterior foot corners are rounded, not developed into tentacles, another Cuthona character. Of course we would need to look, at at least the radula, to be sure.

The other photo, which I have posted alongside my reply, is quite different. You can see the oral tentacles arise right at the edge of the head and there are long tapering tentacular foot corners. These characters, and the colour pattern strongly suggest this is a juvenile Sakuraeolis enosimensis, as you thought [see separate message [#13615].

Best wishes,
Bill Rudman
