Summary: An introduction to bioluminescence, showing a variety of glowing animals on a background of black pages with white text. The “how” of bioluminescence is very briefly described, as well as a variety of reasons why animals glow.  An author’s note explains that some photos have been enlarged and that some are a bit blurry due to the difficulties of photographing animals deep in the ocean.  Thumbnail photos and descriptions of all the animals are included on the last two pages.  32 pages; ages 4-7.

Pros:  Bioluminescence is very cool!  The photos are eye-catching and the text is simple enough for young children.

Cons:  The explanation of why animals glow is very brief.
