Amphibians are ectothermic, tetrapod vertebrates of the class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this.
The long-toed salamander is a mole salamander in the family Ambystomatidae. This species, typically 4.1–8.9 cm (1.6–3.5 in) long when mature, is characterized by its mottled black, brown, and yellow pigmentation, and its long outer fourth toe on the hind limbs. Analysis of fossil records, genetics, and biogeography suggest A. macrodactylum and A. laterale are descended from a common ancestor that gained access to the western Cordillera with the loss of the mid-continental seaway toward the Paleocene.
Rhinella chrysophora, sometimes known as the Rio Viejo toad, is a species of toad in the family Bufonidae. It is endemic to the Cordillera Nombre de Dios on the Atlantic versant in north-central Honduras.
Incilius leucomyos is a species of toad in the family Bufonidae. It was described in 2000 and is endemic to the Atlantic versant of the north-central Honduras.
The Copan brook frog is a species of frog in the family Hylidae found in northeastern Guatemala and northwestern Honduras, specifically in the Sierra del Merendón, Sierra de Omoa, Sierra de Caral, and Sierra Espíritu Santo ranges. The colouring of this species is very distinctive and the specific name soralia comes from the resemblance of its markings to the vegetative structures on some crustose lichens.
Plectrohyla dasypus is a species of frog in the family Hylidae. It is endemic to the Sierra de Omoa in the Cortés Department of northwestern Honduras. The species range is within the Cusuco National Park.
Plectrohyla exquisita is a species of frogs in the family Hylidae. Before its description in 1998, it was confused with Plectrohyla teuchestes. It is endemic to the Sierra de Omoa in the Cortés Department of northwestern Honduras. The species range is within the Cusuco National Park.
Craugastor chrysozetetes is a possibly extinct species of frog in the family Craugastoridae. It is endemic to Honduras where it is only known from near its type locality on the Cerro Búfalo, Cordillera de Nombre de Dios, at the edge of the Pico Bonito National Park. Common name McCranie's robber frog has been coined for this species. However, James McCranie himself has argued that this name "should be rejected in favor of a name associated with the type locality instead of a name tied to one of the three authors who named this species".
The El Cusuco salamander is a species of salamander in the family Plethodontidae. It is endemic to Honduras, and more specifically only to El Cusuco National Park. Its natural habitat is subtropical or tropical moist montane forests. It is threatened by habitat loss.
Bolitoglossa oresbia is a species of salamander in the family Plethodontidae. It is endemic to Honduras and is known from the summit of Cerro El Zarciadero and the southwestern side of the nearby Cerro Azul Meámbar National Park, in the northern Comayagua Department.
Cortes salamander is a species of salamander in the family Plethodontidae. It is found in the Sierra de Omoa in northwestern Honduras and Sierra de Caral in eastern Guatemala, close to the border with Honduras. The vernacular name Cortes salamander refers to the Cortés Department where the type locality is located, whereas the alternative name Cortez' hidden salamander with the spelling "Cortez" and the apostrophe are errors.
Desmognathus fuscus is a species of amphibian in the family Plethodontidae. The species is commonly called the dusky salamander or northern dusky salamander to distinguish it from populations in the southern United States which form a separate species, the southern dusky salamander. The northern dusky salamander is the most widespread representative of its genus in Canada. It can be found in eastern North America from extreme eastern Canada in New Brunswick south into the panhandle of Florida and west to Louisiana. The size of the species' total population is unknown, but is assumed to easily exceed 100,000. The species' habitat differs somewhat geographically; dusky salamanders in the northern part of the range prefer rocky woodland streams, seepages, and springs, while those in the south favor floodplains, sloughs, and muddy places along upland streams. They are most common where water is running or trickling. They hide under various objects, such as leaves or rocks, either in or near water. Alternatively, they may enter burrows for protection. The dusky salamander lays its eggs close to water under moss or rocks, in logs, or in stream-bank cavities. The larval stage which follows is normally aquatic.
Nototriton brodiei is a species of salamander in the family Plethodontidae. It is endemic to the Sierra del Merendón and known from its type locality, Sierra de Caral in Izabal Department, eastern Guatemala, and from the Cusuco National Park in northwestern Honduras. The specific name brodiei honors Edmund D. Brodie Jr., an American herpetologist. Common name Cerro Pozo de Agua moss salamander has been coined for it.
Oedipina cyclocauda, commonly known as the Costa Rica worm salamander, is a species of salamander in the family Plethodontidae. It is found on the Caribbean slopes of northwestern Panama, eastern Costa Rica, Nicaragua, and northern Honduras. The specific name cyclocauda refers to the circular caudal grooves.
Oedipina maritima, commonly known as the maritime worm salamander, is a species of salamander in the family Plethodontidae. It is endemic to Isla Escudo de Veraguas, Panama.
Oedipina stuarti, commonly known as Stuart's worm salamander, is a species of salamander in the family Plethodontidae. It is endemic to Honduras.
Oedipina taylori, commonly known as Taylor's worm salamander, is a species of salamander in the family Plethodontidae. It is found on the Pacific versant in south-eastern Guatemala, to central to north-eastern El Salvador and adjacent southern Honduras. Honduran populations might represent another species.
The green salamander is a species of lungless salamander in the family Plethodontidae. It and the Hickory Nut Gorge green salamander are the only currently-described members of the genus Aneides that inhabit any areas in the eastern half of United States. Rarely seen in the field, the green salamander is an extremely habitat-specific species that is seldom found away from its preferred surroundings: moist, shaded rock crevices.
The spotted-tail salamander, also known as a "cave salamander", is a species of brook salamander.
