Welcome, neighbor! Most jelly species don't get along. In fact, outsiders are fair game as food. Although they're different species, black sea nettles and purple-striped jellies share a genetic heritage, which makes them peaceful—and beautifully contrasting—roommates in the Drifters gallery in the Open Sea exhibit.
While our glorious creatures are home-grown at the Aquarium, in the wild these species share an overlapping range off southern California. Both are considered "giant" jellies since their bells can grow to over three feet wide—and because the black sea nettle's tentacles can grow to over 20 feet long.
