Rana (derived from Latin rana, meaning 'frog') is a genus of frogs commonly known as the Holarctic true frogs, pond frogs or brown frogs. Members of this genus are found through much of Eurasia and western North America .
The Batrachia / b ə ˈ t r eɪ k i ə / are a clade of amphibians that includes frogs and salamanders, but not caecilians nor the extinct allocaudates. [1] The name Batrachia was first used by French zoologist Pierre André Latreille in 1800 to refer to frogs, but has more recently been defined in a phylogenetic sense as a node-based taxon that includes the last common ancestor of frogs and ...
Many frogs use their sticky tongues to catch prey, while others simply grab them with their mouths. [167] Adult frogs are themselves attacked by many predators. The northern leopard frog ( Rana pipiens ) is eaten by herons , hawks , fish, large salamanders , snakes , raccoons , skunks , mink , bullfrogs, and other animals.
Toad is a common name for certain frogs, especially of the family Bufonidae, that are characterized by dry, leathery skin, short legs, and large bumps covering the parotoid glands. [1] [2] In popular culture (folk taxonomy), toads are distinguished from frogs by their drier, rougher skin and association with more terrestrial habitats. [3]

Molecular studies of extant amphibians based on multiple-locus data favor one or the other of the monophyletic alternatives and indicate a Late Carboniferous date for the divergence of the lineage leading to caecilians from the one leading to frogs and salamanders, and an early Permian date for the separation of the frog and salamander groups.
The name was previously used by Frost et al. as a separate genus of ranid frogs that included most of the North American frogs traditionally included in the genus Rana, [7] including the American bullfrog and northern leopard frog. Frost used the name in this sense in the frog section of a North American common names list edited by Crother ...
This is a quite important aspect of their survival, as adult cricket frogs suffer high mortality rates when submerged in poorly oxygenated water (typically less than 24 hours on average in water that is ~1.2 mg/L). [3] The common and scientific names refer to their call, which resembles that of a cricket.
