Pacific sea nettle

(Chrysaora fuscescens)

Georgia Aquarium is home to more than 150 new Pacific sea nettles! Come see the brand new, beautiful jellies on display now in the Tropical Diver Gallery, presented by Southwest. Click here to watch the video of the jellies' journey to Georgia Aquarium! Aquarium biologists ventured into 48° Pacific Ocean water, dodging hefty sea swells and inclement weather, in order to collect the jellies. Through a permit from the State of Oregon, Georgia Aquarium was able to attain the jellies for educational display and husbandry research at the Aquarium. Pacific sea nettles are overly abundant off the coast of Oregon and have become a nuisance to fisherman in the area. The large fluctuation of jellies is thought to be a global indicator of climate change. Georgia Aquarium biologists plan to study the jellies to learn more about this fascinating animal and improve aquaculture techniques. The Pacific sea nettle is common along the coast of California and Oregon and occurs, but is less common, in waters north to the Gulf of Alaska, west to the seas around Japan and south to the Baja Peninsula. The populations of this species are largest during fall and winter. This sea nettle is generally larger than similar species found in the Atlantic. In the wild, it can grow to a diameter of three feet and its thick oral arms can extend 12 feet below the animal. The thin tentacles that hang down from around the edge of its body can inflict a painful sting.

Fun Facts

  • The Pacific sea nettle feeds on small crustaceans, small fish and fish eggs and larvae. It will also eat other jellies.
  • In recent years, these jellies have become so abundant that they appear to be reducing adult fish populations by consuming so many fish eggs and larvae.
  • The concentrations of jellies can become large enough to clog fishing nets and block industrial water intakes.
  • As in other true jellies, the sea nettle exhibits a life cycle that includes both sexual and asexual stages.
  • The genus name Chrysaora has its origins in Greek mythology.
