Ocean Invaders

Enter the world of jellyfish!

Ocean Invaders welcomes you to enter the world of Jellyfish at SEA LIFE London. Stepping into the UK's largest jellyfish experience, Ocean Invaders will take you on a journey into the fascinating world of jellyfish through three unique interactive zones. 

Jellyfish are older than all of our ancient reptiles. Scientists believe they first swam in our oceans around 500 million years ago! There are more than 350 different species of jellyfish.

The Lion’s Mane Jellyfish is over two metres tall – that’s taller than you! Others are as tiny as a pinhead. They can be found in all of our oceans and sometimes in freshwater too.

Jellyfish have venomous tentacles that they use to capture their prey. Most jellyfish are harmless to humans, but a few including the Box Jellyfish can cause a painful sting. Some species of baby fish are able to hide amoungst Jellyfish tentacles for protection!

Ocean Invaders will allow you to see jellyfish in a whole new light! Continue to read below to learn more about the types of Jellyfish you will see on your visit.
