A tadpole is the larval stage in the biological life cycle of an amphibian. Most tadpoles are fully aquatic, though some species of amphibians have tadpoles that are terrestrial. Tadpoles have some fish-like features that may not be found in adult amphibians such as a lateral line, gills and swimming tails. As they undergo metamorphosis, they start to develop functional lungs for breathing air, and the diet of tadpoles changes drastically.
Corroboree frogs comprise two species of frog native to the Southern Tablelands of Australia. Both species are small, poisonous ground-dwelling frogs. The two species are the southern corroboree frog and the northern corroboree frog. They are unique among frogs in that they produce their own poison rather than obtain it from their food source as is the case in every other poisonous frog species.
The strawberry poison frog, strawberry poison-dart frog or blue jeans poison frog is a species of small poison dart frog found in Central America. It is common throughout its range, which extends from eastern central Nicaragua through Costa Rica and northwestern Panamá. The species is often found in humid lowlands and premontane forest, but large populations are also found in disturbed areas such as plantations. The strawberry poison frog is perhaps most famous for its widespread variation in coloration, comprising approximately 15–30 color morphs, most of which are presumed to be true-breeding. O. pumilio, while not the most poisonous of the dendrobatids, is the most toxic member of its genus.
The harlequin poison frog, also known as harlequin poison-dart frog, is a species of poison dart frog endemic to the Chocó region of western Colombia. The frog is normally found on the ground of tropical rain forests, among fallen limbs or leaf litter. Some frogs traditionally classified as Oophaga histrionica were separated as new species in 2018. These are Oophaga anchicayensis, Oophaga andresi and Oophaga solanensis.
The golden poison frog, also known as the golden dart frog or golden poison arrow frog, is a poison dart frog endemic to the rainforests of Colombia. The golden poison frog has become endangered due to habitat destruction within its naturally limited range. Despite its small size, this frog is considered to be the most poisonous extant animal species on the planet.
Indirana beddomii, Beddome's leaping frog, Beddome's Indian frog, or simply Beddome's frog, is a species of frog found in the Western Ghats. They are usually detected by their long leaps as they flush from the ground when disturbed. The species is named after the naturalist Richard Henry Beddome.
Indirana brachytarsus is a species of frog found in the Western Ghats of India.
Hyalinobatrachium fragile is a species of frog in the family Centrolenidae. It is endemic to the Venezuelan Coastal Range. In Spanish it is known as ranita de cristal fragil.
The polkadot poison frog is a species of frogs in the family Dendrobatidae endemic to Panama, where it is known as rana venenosa in Spanish. Its natural habitats are humid lowland and montane forests. It is threatened by habitat loss and is listed by the IUCN as being "critically endangered".
The granular poison frog or granular poison arrow frog is a species of frog in the family Dendrobatidae, found in Costa Rica and Panama. Originally described as Dendrobates granuliferus, it was moved to Oophaga in 1994. Its natural habitats are tropical humid lowland forests; it is threatened by habitat loss.
Lehmann's poison frog or the red-banded poison frog is a species of frogs in the family Dendrobatidae endemic to a small part of western Colombia. Its natural habitats are submontane tropical rainforests. It is threatened by habitat loss and collection for the pet trade, and the IUCN lists it as being "critically endangered". It was named after Colombian conservation biologist Federico Carlos Lehmann.
The splendid poison frog is an extinct species of poison dart frog that was endemic to the eastern end of Cordillera de Talamanca, western Panama. Its natural habitats are humid lowland and montane forests.
Oophaga sylvatica, sometimes known as its Spanish name diablito, is a species of frog in the family Dendrobatidae found in Southwestern Colombia and Northwestern Ecuador. Its natural habitat is lowland and submontane rainforest; it can, however, survive in moderately degraded areas, at least in the more humid parts of its range. It is a very common frog in Colombia, but has disappeared from much of its Ecuadorian range. It is threatened by habitat loss (deforestation) and agricultural pollution and sometimes seen in the international pet trade.
The Chamula mountain brook frog is a species of frog in the family Hylidae endemic to Chiapas, Mexico. Its natural habitats are moist montane forests. It is threatened by habitat destruction and has been rated as "endangered" by the IUCN.
The Hewitt's ghost frog is a species of frog in the family Heleophrynidae. It is endemic to Eastern Cape Province, South Africa. Its natural habitat is fynbos heathland and grassy fynbos. Adults are difficult to see but live in or near fast-flowing perennial rivers and streams where they also breed. Each female lays up to 200 eggs. Tadpoles are more readily seen and take two years to develop fully.
Oophaga is a genus of poison-dart frogs containing twelve species, many of which were formerly placed in the genus Dendrobates. The frogs are distributed in Central and South America, from Nicaragua south through the El Chocó to northern Ecuador. Their habitats vary with some species being arboreal while other being terrestrial, but the common feature is that their tadpoles are obligate egg feeders. Most species in this genus are seriously threatened and O. speciosa is already extinct.
Vampyrius vampyrus is a medium-sized species of flying frogs endemic to Vietnam. It is found in southern Vietnam, and is not known to be found in other places globally. It Is in the kingdom Animalia, phylum Chordata, and class Amphibia. Along with this, it is in the order Anura, family Rhacophoridae, and it is the only member of the genus Vampyrus. It is also known as the vampire tree frog or the vampire flying frog because of the presence of a pair of fang-like hooks in the mouth of the tadpoles.
Ranitomeya sirensis is a species of poison dart frog found in the Amazonian rainforests of northern Bolivia, westernmost Brazil (Acre), and eastern Peru.
Rhacophorus kio is a species of flying frog in the family Rhacophoridae and is found in the rainforests of southeast Asia, in countries such as China, Laos, Thailand, and Vietnam. Its ability to glide and its adhesive toe pads make it well adapted to its habitat of the rainforest. Prior to a 2006 study by Annemarie Ohler and Magali Delorme, R. kio and R. reinwardtii were thought to be the same species. The common name black-webbed treefrog can refer to either species. Compared to other frog species in the area, R. kio not only creates a foam nest that holds their eggs, but also creates a structure with leaves that will wrap around the eggs. While the conservation status of the species is currently classified as of least concern by the IUCN Red List, R. kio faces habitat loss from deforestation to make space for agriculture and other human influences.
Oophaga solanensis is a species of poison dart frog in the family Dendrobatidae. It was described by the herpetologists Andrés Posso-Terranova and Jose Andrés in 2018 and is named for the municipality of Bahía Solano, where it was first discovered. It is a large poison dart frog with an average snout–vent length of 36.2 ± 1.7 mm (1.425 ± 0.067 in). It has a dark black background color marked with variable orange or red spots and "bracelet"-like patterns on the limbs. Typically, there are four to five rounded or oval spots arranged in a line along the middle of the back, one or two spots on the sides, and sometimes another spot around the tympanum. There are bracelet-like bands on the upper and lower limbs, usually incomplete on the underside. The throat and chest have several spots. The fingers and toe tips are black and the skin is smooth.
