Native oysters are a staple of our seas and our plates - but our love of their taste has lead to a sharp decline all around the UK.

This sponge is found on rocky shores around the UK and looks like a thick bready crust (if you use your imagination a bit!).

These moths can be seen flying on sunny days, but you're more likely to spot the fuzzy caterpillars crawling over paths.

This purply-brown seaweed is a common feature on our rocky shores and on our dinner plates.

Also known as the flat topshell, these are one of the most common and colourful sea snails you are likely to see when out on a rockpool safari!
