Storm Ophelia Washes Up Portuguese Man o' War Jellyfish On The Shore At Sidmouth

SIDMOUTH, ENGLAND - OCTOBER 17: A sign warns of Jellyfish that have been washed up on Sidmouth beach by yesterday's ex-hurricane Ophelia in Sidmouth on October 17, 2017 in Devon, England. People have been warned to take extra care close to the coastline today after reports of deadly Portugese man o'war being washed inland by ex-hurricane Ophelia. The so called 'Floating Terror', which is in fact not a jellyfish but a floating colony, has long tentacles that can cause a painful sting and be fatal in extremely rare cases.
