Description

This is the largest order of amphibians known commonly as frogs and toads. In the adult form, they are tail-less, have large eyes, short and compact bodies, rigid backs, and hind limbs that are considerably longer and more muscular than the forelimbs. The long hind limbs enable many species to leap great distances on land. Many species have toxic skin secretions, and these frogs are usually brightly coloured.

Frogs are typically nocturnal, carnivorous, and lay their soft, gelatinous eggs in water. The gilled and legless fish-like tadpoles that emerge are aquatic, feeding on algae, plant matter or detritus. They undergo a series of morphological changes, losing gills and their tail as they develop into air-breathing adults with legs. During the breeding season, males of many species use their distinctive calls to attract mates. Members of the family Bufonidae are generally known as toads.
