Animals, Animals Written by Ned Jensen
Introduction Everywhere in the world, you can see many kinds of animals. All these animals are living things that move, eat, grow, and have babies. All animals need certain things. They need food, water, and air. They also need a place to live.
Body Coverings and Parts When you look at animals, you probably see that some are covered with fur and others are covered with feathers. Still others have scales or a shell. And some are covered only with skin. Wowser! As a snake grows, it has to shed its old skin and grow new skin.
Animals come in many shapes and sizes. Most animals have many of the same parts. The parts of one kind of animal often look different from the parts of other kinds of animals.
For example, the nose of an elephant looks different from the nose of a rabbit. The elephant's ears look different than the ears of a rat. What parts of the animals on page 6 look different? Wowser! The blue whale is the biggest animal. It can be as long as three school buses. It has a heart as big as a small car.
Animals come in many colors. Some animals are only one color. Other animals have many different colors. Some have stripes, while others have spots.
