Swimming bell of the Atlantic sea nettles up to 10 inches (25 centimeters) in diameter, but most are much smaller sea nettles. The edges of the pool are bell-shaped petal. A large tentacle comes out between the leaves, and twice as many small tentacles emerge from under the petals. Eight sense alternative structures are present in spaces between the petals. The narrow oral arms are long and thin. The colors of Medusae vary from milky white to white with purple-red stripes radiating to the bell.


Atlantic sea nettle medusae swim continuously in slow circles. They constantly feed. The life cycle of sea nettles have both a polyp and a medusa stage. The release of eggs and sperm takes place around dawn. Stinging sea nettles are carnivorous. They generally feed on zooplankton, ctenophores, other jellies, and sometimes crustaceans. Nettles immobilize and obtain their prey using their stinging tentacles. Then the prey is transported to the gastro-vascular cavity where it is later consumed. Nettles also eat young minnows, bay anchovy eggs, worms and mosquito larvae.
