Yesterday morning was misty and it was high tide, so I spent an hour on quite a small strip of beach at Cliff End. There was a lot of evidence of gulls feeding on crabs again, with various bits lying amongst the seaweed. The picture shows the claws of, from left to right:
Goneplax rhomboides [no English name], this is a striking looking crab with very long main claws, Velvet Swimming Crab, with a close up to show the beautiful blue markings, Edible Crab, and claws of , I think, Common Shore Crab.
So this small stretch of beach has so far revealed evidence of 6 species of crabs in our waters; it would be nice to see the living animals..
