There are many different kinds of animals found around the world, and each species has a name that helps us identify and talk about it. These names fall into two categories: common names and scientific names. Common names are the everyday names we use for animals in different languages and cultures. example ("Dog" in English, "Perro" in Spanish, "Chien" in French).
To avoid confusion, scientists use a universal naming system called binomial nomenclature. This system gives each species a unique two-part Latin name: Genus and Species. Example (Common name: Asian elephant and Scientific name: Elephas maximus).
