Crab 2

We're back from our trip up to Exmouth and the Ningaloo Reef.  We camped in the Cape Range National Park, which includes the beaches along the Ningaloo Reef.  You can just walk out into the water and snorkel and swim and see a stunning variety of corals and reef fish, no need for a boat or canoe to get to them. 
Here's another view of a crab, same species as the other one, but a different individual.
