Aeolidia papillosa from New England

June 19, 2001
From: Paul Young

Dear Bill,
Locally this is called a 'Maned Nudibranch'.

They are common in the early Spring, south of Cape Cod. These were photographed at Fort Wetherhill, Jamestown, Rhode Island. [Atlantic coast, USA].

They eat anemones. We think they eat Metridium anemones, but in this photo they are surrounded by lined anemones so maybe they eat those too. Big ones are 3-4 cm long.

We believe this is Aeolidia papillosa.

Dear Paul,
Thanks for this message and the others you have just sent on nudibranchs from New England, which I will post in the next few days. It is good to get some information on the Atlantic coast of North America.

If you look at the other messages about this species you will see it is reported to feed on quite a few species of anemones.
Best wishes,
Bill Rudman
