Scale-crested Pygmy-tyrant in Costa Rica. Animals are a group of organisms that belong to the Animalia Kingdom. Animals first appeared during the Cambrian explosion some 542 million years ago.
The word "animal" is derived from the Latin word animalis, meaning "having breath".
Animals are heterotrophs, meaning they must consume other organisms as food. Most animals are also capable of moving spontaneously and independently. Animals are eukaryotic — meaning their cells have a nucleus in which genetic material is carried. Most animals are multicellular.
The best-known animals are vertebrates in the Chordata phylum (fish, amphibians, reptiles, birds, and mammals), but the vast majority of organisms in the Animal Kingdom are arthropods, which include insects, arachnids, crustaceans, and some other creatures. Vertebrates are the third largest group after arthropods and mollusks (like snails, squid, and clams).
Here are some pictures of animals. After the photos are recent news articles about animals.
