Giant Jellyfish Off British Coasts

Tens of thousands of giant jellyfish are swarming off one of Britain's most popular stretch of coastline.
Record numbers of the 1,5 mt long monsters - which weigh five stone each - were spotted off the Dorset coast. 
The unprecedented invasion of barrel jellyfish may due to over fishing which leaves fewer predators to eat them when they are young and smaller. The jellyfish, which are more than three feet wide, may also have overwintered in the depths of UK waters. (PICTURE BY©Steve Trewhella)
