Crabs.

Not sure what this one is: a new on to me on Runswick beach. The flattened legs and claws suggest a swimming crab, but this one (along with a load of tiny juveniles) was found under a rock.
Update: thanks to Chris and Susannah in comments: we have a Broad Clawed Porcelain Crab.

And this is a pair of shore crabs (Carcinus maenas), most vexed at having been interrupted while mating. Quite right too. Your blogger replaced the rock under which their crabby tryst was taking place, made his excuses and left.

Your first crab looks like a porcelain crab, very similar to our pubescent porcelain crab, pachycheles pubescens. I don't know what species would be found in the UK.

Susannah's right, it's a Broad Clawed Porcelain Crab (Porcellana platycheles). They're not true crabs but are more closely related to the Hermit Crabs and Squat Lobsters.
