New Crab or Common?

I was checking out my tank the other day and found out my poor emerald crab had died I have no clue how he had died but weeks before his death I noticed a couple baby emerald crabs skittering about at night. Anyways I was picking up a frag the other day and noticed something extremely hairy hiding out underneath my colony of hairy mushrooms. I moved the rock that the colony was one and I found a crab I have never seen before in any stores or sights. The crab was about the size of a dime and covered in lots of white hair, not just on his legs but everywhere. He had to of hitchhiked into my tank from some live rock but anyways I was wondering what it was and looked on the internet to find out what the thing was and came across a picture in google when typeing in Hairy White Crab.

The Sight was Google Image Result for http://scienceblogs.com/zooillogix/Common%20Hairy%20Crab.jpg

The picture of the crab was I think a common hairy crab is what it was but none the less is it common in aquaria or in the ocean in general? The article says new species found around island and included this guy in there. The crab is a striking resemblence. I would have included picture of him but I was to stupid to grab my camera and click a few. I havent seen him in a while but I know he is still in there.

 

go to liveaquaria Divers den and see if its a teddy bear crab.

 

It looks more along the lines of the one in the article
