Also known as the brown crab, this large crab is found around all UK shores and is identifiable by the distinctive pie-crust edge to its brown shell.

Edible periwinkles are a common sight when rockpooling and can be found in huge numbers on the shore.

This large round urchin is sometimes found in rockpools, recognisable by its pink spiky shell (known as a test).

This crab is common around all of the UK. If you've ever been rockpooling or crabbing, it's probably the shore crab that you've met.
