Blue Blubber Jelly

Also known as Jelly Blubber, Blubber Jellyfish

Unlike typical jellyfish, blue blubbers lack long stinging tentacles along the margin, relying instead on eight thick, ruffled oral arms to trap microscopic plankton. Their coloration varies strikingly by latitude: southern Australian populations often gleam vivid blue or purple, while warmer northern individuals appear creamy white to earthy brown from photosynthetic algae hosted in their tissues. Vast blooms congregate in sunlit estuaries on calm summer days, rhythmically pulsing toward the surface to maximize sunlight for their algal partners.
