National Marine Week

National Marine Week

National Marine Week

Dive into our mysterious underwater world with The Wildlife Trusts' annual celebration of all things marine! National Marine Week is now over for 2023, but don't worry, we'll be back next year! You can still find out about our magnificent seas below as well as some of the mysterious creatures that live there.

We owe so much to our seas. Our marine areas are key to tackling climate change and have also had an enormous cultural impact on society. Our rocky coastlines, sandy beaches and sublime seas are wonderful places to explore. It's no surprise that throughout history this fascinating habitat has inspired many a storyteller, artist and poet, making our lives all the richer.

You may have spotted that National Marine Week actually lasts longer than a week. This is so we can make the most of the different tide times around the country.

For 2023, we focused on the unsung heroes of the marine world. These are species you might not have known we get in the UK, some you might not have ever heard of before. Scroll down to learn about them!
