Craugastoridae
Craugastoridae, commonly known as fleshbelly frogs, is a family of New World direct-developing frogs. As delineated here, following the Amphibian Species of the World, it contains 129 species. They are found from the southern United States southwards to Central and South America. Taxonomy The taxon was created by Stephen Blair Hedges, William Edward Duellman and Matthew P. Heinicke in 2008. The taxonomy of these frogs is not yet settled, and other sources may treat the subfamily Strabomantinae as a family, Strabomantidae, with correspondingly smaller Craugastoridae. The family was rearranged in 2014, and more recently in 2021. Life history With the possible exception of ''Craugastor laticeps'' that may be ovoviviparous, craugastorid frogs have direct development: no free-living tadpole stage is known; instead, eggs develop directly into small froglets. Genera Two genera are recognised in the family Craugastoridae: * ''Craugastor'' Cope, 1862 (126 species) * ''Haddadus'' Hedges, ...

Craugastor Laticeps
''Craugastor laticeps'' (common name: broad-headed rainfrog, and many variations) is a species of frog in the family Craugastoridae. It is found in Belize, Guatemala, Honduras, and southern Mexico. ''Craugastor laticeps'' occurs in leaf-litter in lowland and premontane tropical forest. It tolerates moderate habitat alteration and can be found in cacao and coffee plantations. There are some threats to this species due to habitat loss. Reproduction ''Craugastor laticeps'' might be unique among craugastorid frogs (which normally have direct development): one observation suggests that the species is ovoviviparous Ovoviviparity, ovovivipary, ovivipary, or aplacental viviparity is a term used as a "bridging" form of reproduction between egg-laying oviparous and live-bearing viviparous reproduction.

Atopophrynus
''Atopophrynus'' is a genus of frogs. It is monotypic, being represented by a single species, ''Atopophrynus syntomopus'', also known as the Sonson frog. Its taxonomic placement within the superfamily Brachycephaloidea is uncertain, although many sources place it in the family Craugastoridae. It is endemic to Colombia and only known from its type series from Sonsón, in the Cordillera Central, Antioquia Department. Description The type series consists of three adult females, all measuring about in snout–vent length. The head is narrower than the body. The snout is short, oval in dorsal view and protruding in lateral view. Tympanum is absent. The canthus rostralis is rounded. Skin is smooth apart from a few scattered subconical tubercles dorsally. The fingers are basally webbed and, except the first one, bearing obvious rounded pads. The toes are almost fully webbed and bearing broad discs. Dorsal coloration is red with green markings overlain with white flecks, especially on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frog
A frog is any member of a diverse and largely Carnivore, carnivorous group of short-bodied, tailless amphibians composing the order (biology), order Anura (ανοὐρά, literally ''without tail'' in Ancient Greek). The oldest fossil "proto-frog" ''Triadobatrachus'' is known from the Early Triassic of Madagascar, but molecular clock, molecular clock dating suggests their split from other amphibians may extend further back to the Permian, 265 Myr, million years ago. Frogs are widely distributed, ranging from the tropics to subarctic regions, but the greatest concentration of species diversity is in tropical rainforest. Frogs account for around 88% of extant amphibian species. They are also one of the five most diverse vertebrate orders. Warty frog species tend to be called toads, but the distinction between frogs and toads is informal, not from Taxonomy (biology), taxonomy or evolutionary history. An adult frog has a stout body, protruding eyes, anteriorly-attached tongue, limb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pristimantis Erythros
''Pristimantis erythros'' is a species of amphibian in the family Craugastoridae, and can be found in Cajas National Park in Chiquintad parish, Ecuador. Its striking characteristics are its scarlet red coloration, which differentiates it from all the species of the genus ''Pristimantis'', and the presence of parotid glands on the trapezius and suprascapular muscles. It has an average length of 38 to 42 millimeters in females and 37 millimeters in males. It has direct development, as do all the species of its genus, and does not have an aquatic larval stage. It was described on April 20, 2018, in the scientific journal ZooKeys by a group of six researchers. Its specific epithet derives from the Greek word ἐρυθρός (''erythros''), meaning red, an allusion to its unique coloration. It has not yet been catalogued by the International Union for Conservation of Nature, but because it is losing habitat and occupies an area smaller than one square kilometer, researchers classify ...

Brachycephaloidea
Brachycephaloidea (terrarana) is a monophyletic group of frogs that includes the families: Brachycephalidae, Craugastoridae, Eleutherodactylidae, Ceuthomantidae, and Strabomantidae. The superfamily contains 882 species that inhabit the New World tropics, subtropics, and Andean regions. The group has undergone extensive changes in its taxonomy thanks to multiple molecular phylogenetic In biology, phylogenetics (; from Greek φυλή/ φῦλον [] "tribe, clan, race", and wikt:γενετικός, γενετικός [] "origin, source, birth") is the study of the evolutionary history and relationships among or within groups o ... analyses in recent years.

Pristimantis Orcesi
''Pristimantis orcesi'' is a species of frog in the family Strabomantidae. It is endemic to the Andes of central and northern Ecuador. The specific name ''orcesi'' honors , an Ecuadorian naturalist. Common names Orces robber frog and Bolivar robber frog have been proposed for this species. Description Adult males measure and adult females in snout–vent length. The snout is short and rounded. The tympanum is visible. The fingers and toes bear lateral fringes as well as discs at their tips. The dorsum is dark chocolate-brown or black with white warts. The venter is paler than the dorsum. The iris is deep chocolate-brown. Males have a vocal sac. Habitat and conservation ''Pristimantis orcesi'' is associated with terrestrial bromeliads and rocks in dry páramo grassland at elevations of above sea level near small steams that retain some moisture. Development is direct (i.e., there is no free-living larval stage). It is potentially threatened by feral cows and fire. It is know ...

Tadpole
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. A few amphibians, such as some members of the frog family Brevicipitidae, undergo direct development i.e., they do not undergo a free-living larval stage as tadpoles instead emerging from eggs as fully formed "froglet" miniatures of the adult morphology. Some other species hatch into tadpoles underneath the skin of the female adult or are kept in a pouch until after metamorphosis. Having no hard skeletons, it might be expected that tadpole fossils would not exist. However, traces of biofilms have been preserved and fossil tadpoles have ...

Amphibian Families
Amphibians are four-limbed and ectothermic 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 young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in recent decades there has been a dramatic decli ...
