In One Glance
Bioluminescence is produced when organisms use a chemical reaction to emit light, often involving molecules like luciferin and enzymes like luciferase. Many marine organisms glow, especially in deep water where sunlight doesn’t reach. Light can serve different purposes: signaling to mates, warning predators, luring prey, or blending in with faint surface light (counterillumination). Fireflies are a familiar land example. The story frames glowing life as calm nighttime wonder.
