“Blue Blubber”, Monterey Bay Aquarium
Nicknamed the “blue blubber,” this jelly isn’t always blue. Some blubber jellies come in shades of chalky white or plum purple.
Why does this drifter don so many different hues? Scientists still aren’t sure, but they tend to find the bluest blubbers in clear ocean water. In bays and rivers, blubber jellies wear earth tones instead.
