Additional Information

  • Young cancer crabs are often found clinging to this jelly, even inside the gut. The crab helps the jelly by eating tiny, parasitic crustaceans that feed on and damage the jelly.
  • While the sting of this jelly is not fatal, it may be painful to humans.
  • Unlike other species of jellies, this species does not form large surface aggregations.
