Anura

Anura

Anura (/əˈnʊərə/), also known as frogs and toads, is an order of amphibians comprising over 7,300 species. The name is derived from the Ancient Greek words 'an-' meaning 'without' and 'oura' meaning 'tail', referring to the defining characteristic of these animals.

Etymology

The term "Anura" is derived from the Ancient Greek words 'an-' meaning 'without' and 'oura' meaning 'tail'. This is a reference to the defining characteristic of Anura, which unlike many other amphibians, do not have a tail in their adult form.

Characteristics

Anura are characterized by their lack of tail, long hind legs adapted for leaping, and a short body. They have a large head with bulging eyes and usually have a moist skin. The order includes animals commonly known as frogs and toads, although the distinction between these is not made in scientific nomenclature.

Classification

Anura is an order within the class Amphibia. It is further divided into three suborders: Archaeobatrachia, Mesobatrachia, and Neobatrachia. These are distinguished by various anatomical and physiological characteristics.
