As its name suggests this is the most common crab encountered on our shores. They are usually a green-ish colour, often found in rockpools and shallow waters. They are incredibly tough and adaptable, tolerating a wide range of water temperatures and habitats!

These active predators can commonly be found in rockpools, but also up to depths of 600m! They have pretty gross eating habits - eating shellfish by pulling their shells open with their arms and pushing their stomach out of its body to dissolve and ingest their prey!

These large round spiky creatures can be found in rockpools around the UK. They are usually pink in colour with short spines. They are grazers - eating seaweed, barnacles and anything else they can find!
