About Sealife Adventure

Do you love all things aquatic? Or have you got a budding marine biologist in the family? Then dive under the waters of the world at Sealife Adventure.

The South East’s premier aquatic attraction has over 40 displays featuring sea life from across the world. There are exhibitions and talks aimed at all ages – visit Ray Bay and spot the friendly expression on their faces as they swim up the tank. Listen to the experts talk about sharks and the risks they face from over fishing, spot up to five poisonous frogs in the Crocs and Frogs section and go even deeper in the HMs sub-tropical room.

Turtle Bay is home to lots of species of turtles, many of which have been rescued, along with seahorses. Don’t forget to ask the staff to see if there are any babies! In the Clownfish tank see how many Marlins and Nemos you can count and make sure you check out the super slimy and scaly inhabitants of The Scale Trail and Crawl Wall.
