Kingdom Animalia

What do all animals have in common? What makes an animal an animal?

  1. Animals cannot make their own food. Some animals eat plants to supply their energy needs, some animals eat other animals, and some eat both plants and animals.
  2. Animals digest their food, large food particles are broken down into smaller substances that their can use.
  3. Most animals can move from place to place. They move to find food, shelter and mates and to escape from predators.
  4. Animals are many celled organisms that are made of many different kinds of cells. These cells digest food, get rid of wastes, and reproduce.
  5. Animal cells are eukaryotic cells.

Animal Classification: Scientists place all animals into smaller related groups. They begin by separating animals into two distinct groups – vertebrates and invertebrates. Vertebrates are animals that have a backbone; invertebrates are animals that do not have a backbone. There are far more invertebrates that vertebrates. About 97 percent of all animals are invertebrates.
