Who is this new crab?

[BCWolfen]

I saw some movement in a hole today which at first I thought was just some sand shifting or something. Until it moved again! After much patient waiting I finally got the best pic I could of this unknown crab. I don't have a macro so this is as good as it gets. I left my cleaner shrimp in teh frame for size reference. His body and arms are white, the pincer itself is black/green as is his 'mask'. His legs are white and fuzzy. He is hiding in the hole in the centre of image.

Can anyone ID this masked marauder?

So I thought I'd take a flashlight stroll through the tank, and lo and behold teh new critter was out for a midnight snack. Heres a couple of extra shots to help identify him, they aren't the greastest as the only light source was my flashlight.

"This guy", that is, Borneman, would probably be the one I'd trust.

Hi Kara, welcome to the boards.

Thanks all for your input. Yes it definately looks like a hairy crab.

I'll have to read up some more on them when I get home.
