Thyone fusus

(O.F. Müller, 1776)

Andy Horton Echinodermata

Andy Horton Picture is the sea cucumber Thyone fususe fusus

James Lynott Is it possible to ID this sea cucumber? http://flic.kr/p/f9uDA4 On this particular dive I found dozens of these on the sand/mud/shell slope between around 10-20m depth along with a lot of Psolus phantapus. You can't see the body in my photo but I did see a number with the body exposed and it was white.

Erling Svensen I would say Thyone fusus. I see it now and then here in Norway.....

Erling Svensen My pictures shows that the body is quite white with red dots in the end with the tentacles.

James Lynott Thank you Erling, I had thought T. fusus but I wasn't too sure as on habitas it is described as having a brown body.

Bernard Picton There are several Thyone in the area which look similar. At present we can only distinguish them by checking the spicules in the skin.

James Lynott Thanks folks, really appreciate your input, I still have a lot to learn about identifying marine life and these facebook groups are a great resource.
