Dive in!

National Marine Week is our celebration of UK seas! From 26th July - 10th August 2025 The Wildlife Trusts across the UK, Alderney and Isle of Man will be showcasing the 'Secrets of our Seabeds'.

We have incredible seabeds off the Welsh coasts - from rocky reefs to important seagrass beds, to muds full of life! There are so many beautiful underwater worlds to discover.

Habitat

Mud

From vast plains spreading across the seabed to intertidal flats exposed by the low tide, mud supports an incredible variety of wildlife…

Habitat

Sand and gravel

Sand and gravel can be found from the shoreline down to the deep sea, attracting a host of burrowing creatures.

Habitat

Kelp beds and forests

Forests of kelp sway in shallow sunlit waters, offering shelter to a host of sea life from tiny worms to juvenile fish.

60 Seaside Shore-nanigans

Help us celebrate in style by downloading our '60 Seaside Shore-nanigans' marine pack, crammed full of exciting, family-friendly activities! We've got plenty to keep you busy from the shore or from home, including handy species spotter sheets and ways to get involved with our work!

Shark and skate eggcase hunts

Have you ever heard of a mermaid's purse? These amazing finds are actually the eggcases of sharks and skates.

Each eggcase holds one baby shark which, once hatched, swims away ... the empty eggcases get washed up onto our shores, ready for us to collect!

Learn how to ID the different shark eggcases using this handy guide!

Intertidal rockpooling

Scour the intertidal zone for all sorts of exciting creatures! Use the spotter sheets to tick off which species you've found living within your local rockpools.

Have you noticed the dark red tentacles of the beadlet anemone? Or the blue claws of the velvet swimming crab?

Don't forget, it's really important to stick to the rockpooling code whilst out on shore, and ensure that no animals are removed or injured.
