Sea urchins / Adamson, Heather

"Simple text and full-color photography introduce beginning readers to sea urchins. Developed by literacy experts for students in kindergarten through third grade.".

"Sea urchins look like fireworks exploding underwater. The spines that create their unusual appearance do have a purpose: they protect the tiny animals from dangerous predators. In this title, sea urchins of all shapes, sizes, and colors are on display for early readers!"--From the publisher's web site.
