Found this Crab on the beach at Los Cancajos, La Palma. He(and several others) appeared on the black volcanic rocks everyday as the tide dropped.
Not a marine person, so would love to know what species the crab could be. All help appreciated!

Grapsus adscensionsis

Many thanks Paula for such a quick i'd. I've been trying to work out what this is for ages,but am giving a talk to local natural history group on the plants I saw in La Palma soon and am throwing in a few other bits of wildlife apart from plants which are my main interest, so very pleased to have the id!I assume the colours change as the photos on the net seemed to show a range of colours.
The crabs were a major source of entertainment for us in La Palma, appearing every day as the tide dropped, and got a lot of interest from tourists.They are certainly very colourful!
