Animals are living things that belong to the biological kingdom Animalia1. They are different from plants in having cells without cellulose walls, in lacking chlorophyll and the ability to make their own food, and in having the capacity for movement and response to stimuli2. Animals include many kinds of organisms, such as mammals, birds, reptiles, amphibians, fish, insects, molluscs, worms, corals, sponges, and more1. Animals can be classified into different groups based on their body plan, development, evolutionary history, and other characteristics13. Animals can be found in almost every habitat on Earth and have complex interactions with each other and their environments1. Some animals are used by humans for food, materials, pets, work, or entertainment1.
