Happy holidays from our Reef! Enjoy the best Christmas lights show on the planet. Comb jellies glow thanks to their tiny cilia or hairs that fuse along their body to form a comb. Light scatters in different directions off the hairs, creating a colourful rainbow effect. Our #ocean doesn’t need electricity to sparkle – just the magic of marine life. #tistheseason #lovethereef #christmaslights #jellyfishofinstagram | Great Barrier Reef Foundation
