description Rhizostoma octopus Overview
Rhizostoma octopus is a large scyphozoan jellyfish found in northeastern Atlantic waters and adjacent seas. As a rhizostome jellyfish, it lacks the long marginal tentacles associated with many familiar jellyfish and instead has fused, branching oral arms used in feeding. Its thick, dome-shaped bell can grow to a substantial size, making the species conspicuous to coastal observers, marine biologists, and fisheries monitoring programs when seasonal aggregations occur.
