Placida dendritica? from Taiwan

Note: this is part of a separate message dealing also with a species of Stiliger

Dear Dr. Rudman:
I am Jui-Sheng Chang, a student in National Taiwan University. I am studying the Codium blooming on coral reef in southern Taiwan. I have found two kinds of sea slugs which are living with Codium edule. But I do not know what the species names are....The length of both unknown species is only about 0.5 cm. They can feed with Codium edule and lay eggs on the Codium branches.

Thank you so much for looking my questions.
Your Sincerely
Jui-Sheng Chang

Dear Jui-Sheng Chang,
This is of a species I am tentatively calling Placida dendritica but as you will see if you read the messages on that page, the general feeling is that there are a complex of similar looking species worldwide which will need sorting out. The ramifying green pattern you can see are ducts of the digestive gland containing green chloroplasts from Codium which it probably keeps alive in its body. See the page on Solar powered slugs for information on how these animals utilise the chloroplasts.
est wishes,
Bill Rudman.
