I had my camera set up inside the water housing and was walking down the beach at low tide to swim out into the surf when I spotted this little crab running back and forth from the waters edge to the top of the tide mark in the sand. As soon as I lowered the camera in front of him I think he could see his own reflection in the lens port as he raised his claw and stood up to make himself as large as possible.
It’s rare to stop and look at these crabs for any length of time, if you ever get the chance I suggest it as the colours in their shells are really amazing. Getting close can be difficult as they are usually very timid, I’m just lucky that this guy wanted to fight his own reflection rather than run away!..
