This is a checklist of amphibians found in Northern America, based mainly on publications by the Society for the Study of Amphibians and Reptiles. [1] [2] [3] The information about range and status of almost all of these species can be found also for example in the IUCN Red List of Threatened Species site. [4]
Glass frog. The glass frogs belong to the amphibian family Centrolenidae (order Anura), native to the Central American Rainforests. The general background coloration of most glass frogs is primarily lime green, the abdominal skin of some members of this family is transparent and translucent, giving the glass frog its common name.
The family Plethodontidae is also found in Central America and South America north of the Amazon basin; [46] South America was apparently invaded from Central America by about the start of the Miocene, 23 million years ago. [53] Urodela is a name sometimes used for all the extant species of salamanders. [54]
List of amphibians. The temnospondyl Eryops had sturdy limbs to support its body on land. Red-eyed tree frog (Agalychnis callidryas) with limbs and feet specialised for climbing. Japanese giant salamander (Andrias japonicus), a primitive salamander. The bright colours of the common reed frog (Hyperolius viridiflavus) are typical of a toxic species.
The coastal tailed frog (Ascaphus truei) lives in mountain streams in North America and does not vocalise. [92] The main function of calling is for male frogs to attract mates. Males may call individually or there may be a chorus of sound where numerous males have converged on breeding sites.
Salamanders are a group of amphibians typically characterized by their lizard -like appearance, with slender bodies, blunt snouts, short limbs projecting at right angles to the body, and the presence of a tail in both larvae and adults. All ten extant salamander families are grouped together under the order Urodela from the group Caudata. [2]
