Graceful Decorator Crab: Oregonia gracilis
This 'spider crab' is hard to spot (photo 1 | photo 2) when it's not moving because it attaches seaweed or ehatever else is available to its body so that it can blend in. It is not to hard to spot when it is moving. It can be found intertidally at the lowest tides of the year.
