This Compass Jellyfish Chrysaora hysoscella was stranded on the sand below the cliffs at Hunstanton. The Compass Jellyfish gets its name from the brown, V-shaped markings on the bell which resemble the points of a compass. The long trailing tentacles have a strong venom and produce a painful sting.
I have recently purchased a new book which I have found very interesting to read as well as a useful ID book for the seashore. It is The Essential Guide to Beachcombing and the Strandline by Steve Trewhella and Julie Hatcher.

This fore-dune specialist is extremely range-restricted, known from The Wash, a site in Suffolk, south Wales and in Cornwall. Note the divergence of the wing venation away from the left hand spot and then strong convergence before the wing tip - diagnostic of this species in the British Sciomyzid fauna.
