A Mammal Is an Animal
Sort whales, deer, elephants, birds, fish, and people by the traits that make a mammal a mammal.
Put a blue whale, a bumblebee bat, a platypus, and a child side by side, and the family resemblance is not exactly obvious. Yet all are warm-blooded vertebrates with hair at some point in life, and mammal mothers produce milk for their young. The marvelous exceptions — egg-laying monotremes, sea-going giants, mammals that truly fly — are what make the category much more interesting than a tidy definition in a science notebook.
Drawing from Bookroo’s collection of 5,598 mammal books, our editors selected clear first guides, poetry and read-aloud nonfiction, close looks at remarkable species, and substantial science for older readers. Begin with our ten favorites, then browse by age or follow the related topics toward baby mammals, bats, whales, adaptations, and the animals that ruled after the dinosaurs.
