A small colourful sea slug that can be found grazing on sea mats on the rocky shore and beyond the low water mark.

This strange furry creature often found washed ashore after storms is actually a kind of worm!

These little critters are related to the woodlice you find in your garden and play a very important role on rocky shores.

These mat like growths found on kelp and seaweed are actually colonies of tiny individuals animals.

This bumpy shell lives up to its name and lives partly buried in the seabed along the west coast of Great Britain.

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

Despite its dazzling colouration, this fabulous nudibranch can be easily missed, due to its small size!
