UK Seas

Discover the wonderful sea creatures that inhabit the UK seas and shores

Know the name of the creature you are looking for?

UK seas is a guide to the fauna and flora found around UK coasts. While the majority of species are marine, some species are included that are regularly encountered on land by the coast, so you’ll find descriptions of non-marine species such as reptiles, amphibians, insects and plants as well.

Edible crab

Cancer pagurus


Crustaceans, Crabs


Pinky brown body with a pie-crust edge and chunky black claws. It is the familiar “brown crab” on the fishmongers slab.

Like other crabs, it moults (sheds its outer shell) and can be found as a defenceless softy under beach boulders.


All UK. The lower you can go on the shore improves your chances of finding the really big specimens that inhabit rocky crevices close to the low tideline.
