Giant jellyfish in 'record numbers'

Record numbers of "massive" barrel jellyfish have been reported in UK waters, according to the Marine Conservation Society.

The society said the apparent increases "can no longer be ignored", and called for more research to understand what it means.

Underwater cameraman Rich Stevenson took these pictures of barrel jellyfish off the coast of Plymouth.
