An animal with an outer shell which attaches itself to a surface such as a rock, and feeds by filtering food out of the water using its feathery legs.

A dark blue, black, or brown shellfish that has two long oval shells. You will find them on the rocky shore, clumped together and attached to rocks. Mussels are ‘filter feeders’ that play an important role in the health of our oceans.

A long, fast sea creature with eight arms and two long tentacles. Most squid can change the colour of their skin so that they can blend into the background and avoid being eaten by dolphins!

When an animal sheds its skin a top layer of dead skin comes off them, leaving a new layer underneath.
