The Marine Conservation Society has done the largest ever survey of jellyfish around the coast of Britain.

It's the first time since 1970 that scientists have tried to map where they go. 1,133 jellyfish were spotted in 2013.

Dr Peter Richardson told 5 live Breakfast "The most common species of jellyfish we've had reported to us is the moon jellyfish - a harmless species that occurs all around the UK".
