This handout photograph released by The National Aquarium/Smithsonian National Museum of Natural History on February 13, 2020, shows a Cassiopea Xamachana Jellyfish on display at The National Aquarium in Baltimore. - A species of jellyfish hunts its prey by hurling venom grenades to create "stinging water", researchers said February 13, 2020, solving a long-standing mystery as to how they gather food without tentacles. The Cassiopea xamachana jellyfish, found in shallow waters around Florida, the Caribbean and Micronesia, is a frequent nuisance to snorkelers and surfers who appear to get stung without touching the creatures. It was thought that the stings came from detached tentacles or younger specimens. But a team from the US Naval Research Laboratory realised that Cassiopea had in fact evolved a novel way of hunting without tentacles.
