This big bellied beast washed up on Sidmouth’s shores, catching the eye of a passing walker.
Julian King took a snap of the 30-centimetre-diameter barrel jellyfish on Tuesday in the low tide, far from the depths of its typical English Channel habitat.
Despite reaching a size of nearly a metre, the species lives on tiny plankton and its sting is not powerful enough to harm humans.
The Marine Conservation Society recommends never touching a jellyfish with bare skin and seeking medical attention in the case of a severe sting.
It is conducting a survey of their main predator, the leatherback turtle, and asks that sightings be logged at www.mcsuk.org.
