Known for tentacles that contain toxins used to paralyze and capture prey, these jellyfish also cause painful and annoying stings to swimmers who happen to cross their path. At lower salinities, they are white in color and where salinities are higher, they often have reddish marking along the central tentacles and swimming bell.
Jellyfish venom is made of protein.
Meat tenderizer, which contains enzymes that break down proteins, has been recommended as the best source of relief from stings. Present in Florida panhandle waters. Contact does not normally produce stings in humans.
