Why Do Some Animals Glow in the Dark?Bioluminescent animals use chemical reactions to make light for hunting, hiding, warning, or finding mates.
1. At twilight, Maya crouched beside the forest stream and cupped her hands around a tiny green light. It blinked once, then vanished.
2. Maya opened her notebook. She had seen lamps, candles, and stars, but this light had no wick, wire, or flame.
3. She examined the firefly without trapping it. Its glow came from its body, as if a very small room inside it had switched on.
4. A field biologist named Dr. Imani found Maya by the stream. “Some animals make their own light,” she said. “The word for it is bioluminescence.”
5. Dr. Imani explained that a light-making chemical meets another chemical inside the animal. With the right helpers, the reaction releases energy as light.
6. At the shore, Maya dipped a glass-bottom box into a tide pool. Blue-green sparks curled around it, stirred by the water.
7. Farther out, a comb jelly shone in shifting blue and green bands. The light made it difficult for a hunter below to see its outline.
8. Dr. Imani showed Maya an anglerfish. Its shining lure could bring curious prey close enough to catch.
9. A squid had another plan. When a predator came near, it could release a glowing cloud and slip away while the hunter searched the wrong place.
10. Some lanternfish carry lights that match the faint glow from above. Their bellies disappear against the water, helping them hide.
11. Fireflies use their flashes differently. A careful pattern can help one firefly find a mate of the right kind.
12. Maya added the final sentence to her notes: Bioluminescent animals use chemical reactions to make light for hunting, hiding, warning, or finding mates.
