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

This large, fluffy-looking moth is on the wing in July and August, but you might spot a caterpillar at almost any time of year.

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.

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!

This common fungus puffs out clouds of spores when it's mature.

Brush through a wildflower meadow at the height of summer and you'll hear the tiny seeds of yellow-rattle rattling in their brown pods, hence its name.

Did you know that there are coral reefs in the UK? UK seas are home to some amazing cold-water corals that form reefs on the seabed over 400m deep.

Look out for this tiny crab under rocks and boulders on rocky shores - you'll have to look closely though, they're pretty well camouflaged!
