Southern African Sea Nettle

Chrysaora africana, the purple compass jelly or Southern African Sea Nettle, is a species of jellyfish from the family Pelagiidae. Found in the southeastern Atlantic Ocean from Gabon to the western coast of South Africa (although uncommon in the far south of its range), its taxonomy has historically caused considerable confusion. Like other sea nettles, its sting is painful, but not generally dangerous unless there is an allergic reaction to the venom.
