Lights On‪!‬

Far below the sunlit surface, the ocean isn't dark. It glows.

Meet the viperfish that dangles a living lure to draw prey into its jaws. Watch fireworms rise from the depths in shimmering mating displays. Follow a vampire squid as it explodes into a cloud of light to vanish from predators. From flashing jellyfish and lanternfish to glowing worms and a pocket shark no bigger than your hand, Lights On! reveals the astonishing ways deep-sea creatures make their own light — to hunt, hide, communicate, and survive.

Newly expanded for its second edition, this book pairs Donna B. McKinney's vivid nonfiction storytelling with Daniella Ferretti's atmospheric art — now reviewed for scientific accuracy by two of the world's leading experts on bioluminescence: Dr. Steven Haddock of the Monterey Bay Aquarium Research Institute and Professor Sönke Johnsen of Duke University.

The extensively expanded back matter takes young explorers even deeper:
Play hide-and-seek with animals that vanish using color and see-through bodies

Explore the historic voyages and rescues where living light guided the way home
Uncover the questions about bioluminescence that scientists are still racing to answer
Packed with jaw-dropping science, a glossary, and resources for further discovery, this expertly reviewed edition of Lights On! is a luminous journey into one of Earth's last great mysteries — the world of living light.
