Frogs belong to the biological order Anura, also known as Salientia. This order includes over 7,000 species of amphibians, with frogs making up the majority of these species. Anura means “without tail” in Greek, emphasizing one of the main distinguishing features of this order. Frogs are diverse in shape and size, but they are characterized by a streamlined body, webbed feet, and an ability to jump long distances. The classification of frogs within the order Anura is determined by the presence or absence of certain physical features, such as the presence of teeth, the structure of the shoulder girdle, and the type of ear drum. An understanding of the biological order to which frogs belong is important for studying their taxonomy, behavior, distribution, and ecological roles.
