Four Creatures That Glow

The video explores bioluminescence, a phenomenon where living organisms emit light. It discusses how fireflies use luciferase to glow for mating, ostracods use it as a defense mechanism, and sea sparkle glows to deter predators. The crystal jelly's unique green glow is explained through GFP, a protein with significant scientific applications. The video highlights the evolutionary advantages of bioluminescence and its uses in scientific research, such as visualizing cellular structures and studying gene expression.
