  • SEA LIFE, Jelly Invaders


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 amongst Jellyfish tentacles for protection!

At the National SEA LIFE Centre Birmingham you’ll be able to see jellyfish in a whole new light!
