Summary: The first page defines iridescence as “the rainbow-like shimmer seen on some bird feathers, fish scales, insect bodies and more.”  Each two-page spread after that shows a brilliantly-colored illustration of the iridescent animal with a rhyming couplet and a paragraph of additional information.  The final two pages show all the animals.  Includes additional information about iridescence (including the recent discovery of a dinosaur with iridescent feathers) and a list of sources.  32 pages; ages 4-8.

Pros:  The gorgeous illustrations are sure to catch kids’ eyes, and the brief but informative text will have them looking for iridescent animals wherever they go.

Cons:  Apparently there are no iridescent mammals.
