6-year-old stung by invasive clinging jellyfish in New Jersey river

A six-year-old girl in Ocean County, New Jersey, suffered a severe sting from a rare clinging jellyfish while playing in a river. Unlike common jellyfish, this nearly invisible species causes intense pain that lasts for several days. While the child has fully recovered, experts warn of the species' presence in local waterways before they naturally die off as temperatures rise.
