Neopentadactyla mixta
(Östergren, 1898) Deichmann, 1944
Jeremy Pierce Same dive as yesterday and for me anyway an unusually clear view of the body of a 'Crevice Sea Cucumber'??? Aslia lefevrei, although my book says it's body is brown and leathery!! Or is it a Neopentadactyla mixta out of the gravel and in a crevice??? Cheers JAP :-)Jeremy Pierce Checked another book and may have answered my own question.........Pawsonia saxicola???
Erling Svensen I would have called this one Ocnus lacteus, but this species only grows to 4 cm
Jeremy Pierce This one was approx 11 -14cm!
Erling Svensen Then I think it might be Pawsonia saxcola.
Colin Munro Def. Pawsonia saxicola. Quite common.

Charlotte Bolton Am hoping this is quite a simple Q for the echino experts out there! Lyme Bay, 25m bsl, fairly silty coarse gravel/sand between up-to-0.5m boulders. Is this a Thyone sp.? Can convince myself it looks like the T. ruscovita pic on Habitas but it wasn't in mud... N. mixta also present. TIA for all suggestions/clarifications!Charlotte Bolton Yes, I think there's body exposed there - looks dark to me so Aslia lefevrei? I asked about Thyone because I know we've had it here in Dorset but I haven't noticed it myself; I was slightly unsure about the 'mud' habitat too...
Charlotte Bolton But equally it was more like 'mud' than wedged in a rock crevice... Sigh.
Charlotte Bolton Neopentadactyla mixta was definitely there as well...
Bernard Picton I’d say Thyone roscovita. The top of the body looks right, with a black collar.
