But there was a time when people hunted the otters almost to extinction. Without sea otters to eat them, an army of hungry sea urchins grew and destroyed entire kelp forests. Fish and other animals that depended on the kelp were lost, too. But when people protected the sea otters with new laws, their numbers began to recover, and so did the kelp forests. Susannah Buhrman-Deever offers a beautifully written account of a trophic cascade, which happens when the removal of a single element affects an entire habitat. Asides that dig deeper are woven throughout Matthew Trueman’s dynamic illustrations, starring a raft of charismatic sea otters. Back matter includes more information about sea otters and kelp forests, including their importance and current status, the effects of the international fur trade on indigenous peoples, and a list of books and websites for readers who wish to continue to explore.

     In Elkhorn Slough, an inlet on the California coast, seagrass grows healthy and strong in the shallow water. This healthy seagrass baffled marine biologist Brent Hughes.

As Brent investigated, signs pointed to an unexpected player helping to keep the seagrass healthy: sea otters! What do these top predators have to do with an aquatic grass at the opposite end of the food chain? Brent's discovery gave scientists insight into the delicate balance of ecosystems.

    For example, the zebra gallops, the bumblebee flies, the lemur leaps and the tiger prowls --- ?But look closer now ... We all have STRIPES!? And so it goes. Again and again, readers will be surprised to find that a group of four seemingly different animals all have one trait in common --- whiskers, horns, shells and the like --- for a total of thirteen traits in all. Observant children will notice that one of the animals from each group also appears on the following spread with three new animals that have a different characteristic in common. Finally, all forty of the featured animals are shown together, and readers are asked to search for those with specific characteristics not already covered in the book --- for example, those with spots, those who live in the ocean or those with six or more legs. Author Heather Tekavec has discovered a fun and interactive approach to helping young children begin to explore the ways animals are classified. Pippa Curnick's playful and engaging illustrations of the animals in their habitats are all scientifically accurate, keeping the experience both enjoyable and informative. The searching activity also works to enhance visual literacy. With a detailed glossary included, this is an ideal book for introducing early lessons on the characteristics of living things and for starting discussions on the ways all creatures are like and unlike one another.
