Moon Jellyfish

Aurelia aurita

About

Jellyfish float near the surface of the sea, catching tiny animals and plankton with their stinging tentacles. The Common Jellyfish (also known as the 'Moon Jellyfish') catches plankton in a layer of mucus that covers its body, using its tentacles to sting and catch larger prey. It lives up to its name in British waters and is often spotted washed up on shore.

How to identify

A round, dome-shaped jelly, transparent with four purple, C-shaped markings around the centre.

How can people help

The Common Jellyfish is just that: common. But our seas and coastline are in need of protection if we are to keep our marine wildlife healthy. The Wildlife Trusts are working with fishermen, researchers, politicians and local people towards a vision of 'Living Seas', where marine wildlife thrives. This work has recently had a massive boost with the passing of the Marine Bill, promising sustainable development of the UK's marine environment. Do your bit for our Living Seas by supporting your local Wildlife Trust.
