Need help ID'ing creature

[Jocelyn]

So we went to the beach and found a conch shell laying on the sand a little ways away from the tide. Decided to take it home and put it on a 3 gallon tank and see what happens.... well out came a little creature and I am trying to find out if anyone knows what it is. It's still alive after about a week moving around it doesn't swim it seems to crawl around. Any help or ideas where I can look to figure this out would be great! Thanks : )
Here is the link to the pic of it

I'm wondering if it's a sea slug but who knows it is so small like the size of my thumbnail.

You might want to try in the invertebrate forum. I can move the thread there if you want.

Don't know if it's just me but I cannot get your link to work.

Well it died... I feel bad it wouldn't eat I wish I had known what it was in time to save it. Still curious as to what it is so any hep would still be appreciated. Not sure why the link won't work for you sorry about that but thanks for trying to look!

 

[bertoni]

The link is dead for me now, too.

I will try to post it on my message here

hopefully one of these two will work

It's a juvenile sea cucumber. If it had survived eventually it might have looked like this Eupentacta - http://seanet.stanford.edu/EchinoHoloOphio/index.html#Eupentacta

Thank you Leslie I appreciate knowing. Wish we lived closer to the beach so I could have got it back there... or at least got it to eat something here. Thanks to all that tried to help as well! :thumbup
