What makes an animal a mammal?

And what is not a mammal? Mammals have skeletons as deer have, breathe air in lungs as whales do, and are born alive as are calves. What is not a mammal? A ladybug has no skeleton, a fish breathes through gills and a bird hatches from an egg. Monkeys, dolphins, and elephants are mammals—and so are you and I!

With clear, simple language, beautiful paintings, a chart, diagrams, and a cutaway, acclaimed author-illustrator Lizzy Rockwell has created a beautiful and informative book that introduces young children to animal classification and dichotomous inquiry.

Praise For A Mammal is an Animal

"Quiet, pleasing ink-and-watercolor pictures illustrate the text, and an attractive two-page classification chart shows 'Life on Earth,' divided and subdivided into categories. This picture book provides young children with a simple, informative, age-appropriate introduction to mammals."—Booklist
"Largely eschewing scientific vocabulary in favor of clear explanations (the terms 'vertebrates' and 'invertebrates' are introduced in a diagram in the backmatter), Rockwell’s text focuses on the concepts. The fine-lined ink-and-watercolor illustrations are as clear and straightforward as the text, with the carefully labeled renderings of the animals examined particularly meticulous. . . . A clear, respectful introduction." —Kirkus Reviews
"Ink-and-watercolor illustrations are detailed and complement the text nicely. . . . A solid option for classrooms and libraries"—School Library Journal
"[Readers will] learn plenty about the ways that animals are categorized and classified." —Publishers Weekly
