The northern sea nettle (Chrysaora melanaster), also called a brown jellyfish, is a species of jellyfish native to the northern Pacific Ocean and adjacent parts of the Arctic Ocean. (It is sometimes referred to as a Pacific sea nettle, but this name is also used for Chrysaora fuscescens; the name Japanese sea nettle was used for this species, but that name now exclusively means Chrysaora pacifica.[1][2] This jelly's medusa can reach 60 centimeters in length with tentacles growing up to three meters.[3][4] The number of tentacles is up to 24 (8 per octant).[1] It dwells at depths of up to 100 meters, where it feeds on copepods, larvaceans, small fish, large zooplankton, and other jellies.[4] The sting is mild, although can cause serious skin irritation and burning.[5]
