Living in two worlds
You will be amazed at what you discover when you visit the new National Marine Aquarium in Plymouth. Your breathtaking underwater journey across the planet will reveal a strange and secret world that is both weird and wonderful. You will learn and understand the life of the oceans and their relationships with people. And because the aquarium is a charity, you can be sure that you are helping undersea life!
Amazing use of coral
Thousands of fish and sea animals with bright colours and bizarre shapes live around corals. It is easy for plants to grow there because the water is warm and shallow. The animals eat these plants. These places are important for people, too. Doctors can use medicine made from the coral to treat broken legs. The coral reef is a fantastic window onto the ocean.
The legends and the truth
Come face to face with over ten real live sharks, over two metres long — as close as you can get without getting wet! You will feel the danger but you will be out of danger.
Sharks are some of the most amazing but misunderstood marine animals on the planet. Our guides will help you separate fact from fiction about these hunters of the seas.
A home for weird families
Here you will learn the story of seahorses across the planet. Enter the world of these magical creatures. Find out how they make families for life, what they eat and how a male seahorse manages to give birth to up to 1,500 young! You can see our unique seahorse-breeding programme at first hand and watch seahorse babies.
It’s not only a show
Here animals behave as they usually do in the wild. Many of them are camouflaged and hide in the sand. It looks like the place is empty but the more you look the more you will see. A team of guides is here to help you enjoy your visit. They will reveal the secret life of the creatures that live on the border between the river and the sea.
