A deadly jellyfish left one swimmer with an "uncomfortable rash" after coming into contact with the sea beast on a beach in Devon.
Nicknamed the Portuguese Man o'War, the jellyfish has creepy tentacles which contain enough venom to deliver a painful sting, sometimes with fatal consequences - and it regularly uses its fearsome feelers to kill fish.
The bizarre looking blobs are usually found in the Atlantic Ocean or as far away as the Indian Ocean.
