This gentle giant is the largest shark in UK seas, reaching up to 12m in length. There's no need to fear them though, they only eat plankton!

The moon jelly is the most common jellyfish in UK seas, often washing up on our beaches. No need to worry though - it doesn't sting humans.

The greenshank breeds on the boggy moors and ancient peatlands of Scotland. But it can be spotted elsewhere in the UK as it passes through on migration - look around lakes, marshes and the coast…

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!

The kingfisher blue stripes of a blue-rayed limpet are a magical sight whilst rockpooling - you'll need to go on a very low tide though as their favourite home is on kelp.

Related to the massive albatross, the fulmar is a gull-like bird that nests on rocky cliff edges. Don't get too close, though - it spits a foul-smelling oil at intruders.

Familiar as the bristly plant that easily hooks on to our clothing as we walk through the countryside or do the gardening, cleavers uses its hooks to help it climb and to disperse its seeds.
