Sea Slug ID

Can someone ID this critter?

Found at Murray's Reef, Jervis Bay, Australia.

cheers

It's looks to be Euselenops luniceps. The animal is slightly scrunched up but you can see the characteristic triangular outer edges of the head on the right side of the animal.

Thats the one! Thanks Leslie

cheers

yep - nice finding - very rare seaslug

I don't think it's rare, perhaps just rarely seen. The animals spend a lot of time buried in the sand & usually only come out at night in the sort of soft bottom areas most divers don't bother with.

Definitely rarely seen ... though now I know it has been snapped in Jervis Bay before by a friend of mine ... http://www.seaslugforum.net/display.cfm?id=10022

Thanks again Leslie for the ID!! It makes it so much easier to track down info! There is some good stuff on Euselenops luniceps burrowing on the seaslugforum ... http://www.seaslugforum.net/factsheet.cfm?base=euseluni2

In the photo the slug is just about to disappear into the sand ... thats why it is hunched up in the photo ... it dug its "nose" in and was gone :>

cheers

Rarely seen it is for sure

Nice set of behaviours in those shots

I like your site, am trying to set up something similar (though smaller!!) for our dive club, so that people can ID their critter discoveries more easily. I have been using iMatch categories and a modified web gallery script. Do you mind if I ask how you built / maintain your list of species?

cheers

sure

We have seen a few Euselenops luniceps here in East Timor as well, both times in pairs on a sandy slope at about 12M. In the attached photo, notice the crab hanging in the sand just to the right of the slug.

i have also seen this nudi on a night dive in the Lembeh Strait. I asked the guide what it was and he said it is sometimes called a fullmoon nudi. strangely enough it was a full moon that night....
