How to identify: The commonest crab on our beaches, with pointed spines around the front of the 'face'.

Where: Found all round our shores.

Fantastic fact: The Shore Crab has been introduced to many other parts of the world, including Australia, South Africa and California, where it has become an invasive pest.
