That’s a neat picture, but the ocean is a natural laboratory, not a hideout. The glow of a deep‑sea fish is an evolved tool—attracting mates, hunting, or deterring predators. If alien chemists were around, they’d probably copy our bioluminescence rather than invent something totally new. Still, watching a lanternfish flicker in the abyss feels like peeking into a cosmic laboratory that has been working for eons.
