Couple critters from Redondo

[Chenari]

Well here's a report from the impromptu Club Dive today. Dwashbur I'm sure will be posting his own pics later, but right now I'm looking for some ID help.

First we have a strange little flatworm or something I found on a piece of sea lettuce. It was probably about half an inch to three quarters of an inch, I'm not sure. I'm bad at measuring. This was the only shot I could get, as we were kinda hurrying up a little to lower our deco time lol.

The second... I have absolutely no clue what it is. It looks a lot like the Vermetid Gastropod ( http://i61.photobucket.com/albums/h65/c ... G_1485.jpg ) I found down in Monterey bay, but this guy has some sort of feelers or something around the edge of his shell. The pics are brightened a little for clarity.

And the third is a Hermit Crab that I don't recognize. The closest I could find in Greg's book was the Stevens' Hermit Pagurus stevensae. Little help Greg?

Hi
hermit is the whiteknee hermit, Pagurus dalli. Very similar to stevensae but the white banding is much more distinct. They're common in BC but you don't see them very often inside Puget Sound.
I suspect the second picture is a vermetid gastropod, Dendropoma lituella.

Ah no wonder I couldn't ID the Hermit from your book. It's not in the book! XD Thank you very much Greg.

Anybody know about the sluggy guy? Leslie?

[Greg Jensen]

If you mean the first one, yes, it's a flatworm. But I won't try to go any more specific than that.
I'd guess the other one is a head-on view of a Sabellariid tubeworm, but I'll leave it to our vermiphilic friend Leslie to set us straight.

Flatworm is a perfectly good id, short, to the point, avoids unnecessary waffling about why you can't identify it!

Greg's not bad for a crabby kind of guy. it's a sabellariid, probably an Idanthyrsus. Those long thin brown sausages at the base of the tube are strings of poop. They disintegrate rapidly so they must have been pretty fresh.

Ok I'm a little confused. Could you clarify a bit which one's which?

The one with a white tube (#1) is the gastropod, the other is the worm.
