Christmas decoration

  

 
Since many folks are decorating at this time of year, we thought you might enjoy seeing this local decorator crab.  Meet the Cryptic Kelp Crab (Pugettia richii)!  They're known as decorator crabs because they add pieces of seaweed to their rostrum (nose) and carapace (back) for camouflage.  In the photo above, the narrow red-brown seaweed and the green leafy seaweed are attached to the back of the crab.
 
If you look closely on the backs of the crabs, you can even see the specialized hooks for holding seaweed.  Below, look for the clusters of narrow curved hooks near the base of the seaweed.  The crab pushed the seaweed under these hooks to hold it in place.  The better to hide from fish and octopus!
 
 
Happy Holidays to all!
