Animals are heterotrophs, which means they rely on other organisms to obtain their nourishment. Animals range in size from microscopic animals known as plankton to the massive blue whale. Animals are thought to have evolved from flagellate protozoa and the oldest animal fossils date back 600 million years, to the latter part of the Precambrian.

Pets - People buy and catch animals to keep as pets. Many of the people who have animals as pets do not know how to care for them.
