I’ve been fascinated by anything that glows in the dark since I was a child so when I first heard of bioluminescence I was enthralled. Even now I react with childlike wonder whenever I see sea sparkle photos.
The word bioluminescence is made up of two parts – bio, which means “living thing” and luminescence, which means “light” – so, living light.
This book provides some fun facts about twenty living lights:
- Dinoflagellates
- Velvet Belly Lanternshark
- Gulper Eel
- Anglerfish
- Lanternfish
- Shortnose Greeneye Fish
- Hatchetfish
- Firefly Squid
- Glass Squid
- Bioluminescent Octopus
- Atolla Jellyfish
- Crystal Jelly
- Lined Seahorse
- Bloodybelly Comb Jelly
- Bobtail Squid
- Giant Clam
- Long-Armed Brittle Star
- Midwater Jellyfish
- Sea Pen
- Sea Slug
Although they’re not officially one of the twenty, pyrosome, “the unicorn of the sea”, were also mentioned. I had to look them up because they sounded so interesting. (More info here)
Some of the facts were really interesting.

The Atolla uses its light to attract predators rather than chase them off. It is nicknamed the “alarm jelly” because when threatened, the Atolla flashes blue, bioluminescent light around its ring, like a police siren. It can project its light as far as 300 feet (91 m). When it flashes, curious larger predators come sniffing around and are drawn to the predator that was stalking the jelly.
Others were nightmare fuel.
As a young fish, the male latches onto a female anglerfish like a parasite. After the male digs his sharp teeth into the female, its mouth releases a special chemical that sort of melts her flesh. Over time, the male’s body joins with the female, and he loses all of his internal organs except for his reproductive organs. A female anglerfish can carry more than six males on her body!

Stats provide facts about the length of each sea creature and their diet, as well as the depth and parts of the ocean they are found. Readers will be able to easily visualise the length of each creature because they’re compared to objects like soda cans, baseballs and ice creams. There is a glossary at the end of the book.
As a child I would have probably only used this book for a school project. Adult me loves all of the photos and fun facts. As I’m getting older I’m finding that I’m paying more attention to the beauty that surrounds me. Being able to read little tidbits about different plants and animals only adds to my awe of nature. There are quite a few sea creatures included in this book that I need to learn more about.
Thank you so much to NetGalley and becker&mayer! kids, an imprint of Quarto Publishing Group, for the opportunity to read this book.
