Spider Crab

Fantastic few hours on Grunta Cove today. The sea was warm and we all enjoyed body boarding and searching the enormous rock pools for crabs. Sadly, there were scores and scores of really big spider crabs. Why would there be so many in one place? We thought maybe seagulls, but the live ones were very good at hiding and we didn't see any seagull attacks whilst we were there.

It's a mystery..
