Aeolid? Janolus? Stiliger? from Japan

February 27, 2000
From: Atsushi Ono


Dear Bill,
Thank you for ID of F. rubrolineata.

Here is beautiful Sacoglossa species.
I found this at 3m depth on a rock covered with brown algae. This animal is 7mm long.
The cerata looks like fireworks. I cannot see any sign of rhinophores

This is very rare species in Kerama Is. [near Okinawa, Japan]. I have seen only one individual.

Could you help me to identify this?

Sincerely,
Atsushi Ono.

Dear Atsushi,
I agree from your photos that this beautiful animal looks like a sacoglossan. However by remarkable coincidence I have just received a message from Lindsay Warren with photos of the same animal from Sulawesi in Indonesia. In her photos the rhinophores are clearly visible and their is a crest between them characteristic of Janolus. Perhaps the rhinophores were damged in your animal. However, as I say in her message, I am not sure whether this is an aeolid, sacoglossan or janolid. hopefully someone will recognise it and let us know.
Best wishes,
Bill Rudman
