Anglesey Sea Zoo is a unique aquarium with over 40 tanks displaying the best of British marine wildlife! Instead of large sharks, tropical fish or sea turtles, you’ll find fascinating creatures from around the coasts of the UK, such as octopus, lobsters, seahorses, conger eels and catsharks! You’ll also learn about British marine habitats and the research and conservation work which is helping to save them.
Quirky lumpsuckers, rare British long-snouted seahorses, and mesmerising Moon Jellyfish to name a few! Click here to find out more!
