About Chrysaora pacifica (Goette, 1886)
Chrysaora pacifica, commonly known as the Japanese sea nettle, is a species of jellyfish belonging to the family Pelagiidae. This common species is native to the northwest Pacific Ocean, covering regions including Japan and Korea. In the past, it was frequently confused with C. melanaster, a larger jellyfish species with a more northerly distribution. Because of this confusion, individuals of C. pacifica held in public aquariums have often been incorrectly labelled as C. melanaster. The bell of mature medusae of C. pacifica typically measures 15 to 21 cm (5.9 to 8.3 inches) in diameter. The sting of this jellyfish is strong and can be dangerous to humans.
