Dozens of jellyfish wash up on Cornish beach during heatwave

Dozens of jellyfish have washed up on a beach in Cornwall as the warm weather heats up the sea.

The footage, captured on July 25, shows dead jellyfish lying on the sand at Portreath beach.

The filmer writes: ''I took my dachshund for a walk this evening after it had cooled down and I was shocked at the number of jellyfish washed up on the beach.''
