Chile Darwin's Frog
The Chile Darwin's frog (''Rhinoderma rufum''), also called the northern Darwin's frog, is one of only two members of the family Rhinodermatidae. It is endemic to central Chile, although it might well be extinct. Description The Chile Darwin's frog has a snout to vent length of about . It has a fleshy proboscis, slender limbs and feet webbed between the first and second, and the second and third toes. The dorsal colour is variable but is usually some shade of brown or green, or a mixture of the two. The ventral surface is mottled in black and white. Biology The Chile Darwin's frog is diurnal and feeds on small insects and other invertebrates. The female lays a small clutch of eggs on moist ground. About a week later the embryos are beginning to move within the eggs and the male picks them up and stores them in his vocal sac. He keeps them there until they have developed a functioning gut and then transports them to a suitable water body and releases them. The tadpoles grow furth ...

Rodolfo Amando Philippi
Rodolfo Amando (or Rudolph Amandus) Philippi (14 September 1808 – 23 July 1904) was a German–Chilean paleontologist and zoologist. Philippi contributed primarily to malacology and paleontology. His grandson, Rodulfo Amando Philippi Bañados (1905-1969), was also a zoologist and in order to avoid confusion in zoological nomenclature, the elder is referred to as "Philippi rumwiede to distinguish him from his grandson "Philippi añados. Early life Philippi was born in Charlottenburg, Berlin to Johann Wilhelm Eberhard Philippi, a Prussian government auditor, and his third wife Maria Anna Krumwiede (m. 1806). The father had five children from two earlier marriages and Philippi was the eldest from the third marriage. In 1818, Philippi, his younger brother Bernhard Eunom (1811–1852) and their mother went to Yverdon-les-Bains, Switzerland, where they were educated at the Pestalozzian Institute founded by Johann Heinrich Pestalozzi (1746–1827). The teaching included the use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Batrachochytrium Dendrobatidis
''Batrachochytrium dendrobatidis'' ( ), also known as ''Bd'' or the amphibian chytrid fungus, is a fungus that causes the disease chytridiomycosis in amphibians. Since its discovery in 1998 by Lee Berger, the disease devastated amphibian populations around the world, in a global decline towards multiple extinctions, part of the Holocene extinction. A recently described second species, '' B. salamandrivorans'', also cause chytridiomycosis and death in salamanders. The fungal pathogens that cause the disease chytridiomycosis ravage the skin of frogs, toads, and other amphibians, throwing off their balance of water and salt and eventually causing heart failure, Nature reports. Some amphibian species appear to have an innate capacity to withstand chytridiomycosis infection due to symbiosis with ''Janthinobacterium lividum''. Even within species that generally succumb, some populations survive, possibly demonstrating that these traits or alleles of species are being subjected to evo ...

Gastric-brooding Frog
The gastric-brooding frogs or platypus frogs (''Rheobatrachus'') is a genus of extinct ground-dwelling frogs native to Queensland in eastern Australia. The genus consisted of only two species, both of which became extinct in the mid-1980s. The genus is unique because it contains the only two known frog species that incubated the prejuvenile stages of their offspring in the stomach of the mother. The combined ranges of the gastric-brooding frogs comprised less than . Both species were associated with creek systems in rainforests at elevations of between . The causes of the gastric-brooding frogs' extinction are not clearly understood, but habitat loss and degradation, pollution, and some diseases may have contributed. The assignment of the genus to a taxonomic family is hotly debated. Some biologists class them within Myobatrachidae under the subfamily Rheobatrachinae, but others place them in their own family, Rheobatrachidae. Molecular genetics finds it sister to '' Mixophye ...

Betic Midwife Toad
The Betic midwife toad or Sapo Partero Bético (''Alytes dickhilleni'') is a species of frog in the family Alytidae (formerly Discoglossidae). It is endemic to mountainous in south eastern Spain. Its natural habitats are temperate forests, freshwater marshes, intermittent freshwater marshes, pastureland, ponds, and aquaculture ponds. It is threatened by habitat loss. Description The Betic midwife toad is grey, finely mottled with dark and pale specks. Its length may be about and it has bulging eyes with vertical slit pupils. There is a distinctive grey area between the eyes and the parotoid glands are relatively small. There is a lateral line of whitish glandular tubercles on the body but an absence of the orange glandular spots found in other members of the genus. Distribution and habitat The Betic midwife toad is native to the Sierra Nevada Mountains in south eastern Spain. The population is fragmented as different mountains support separate populations. It is fairly common o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scaphiophryne Gottlebei
''Scaphiophryne gottlebei'', commonly known as the Malagasy rainbow frog, ornate hopper, rainbow burrowing frog, red rain frog or Gottlebe's narrow-mouthed frog, is one of the most highly decorated frogs from Madagascar. The primary threats to this endangered species are habitat loss and capture for the pet trade (now illegal). Description The Malagasy rainbow frog is a small, roundish, brightly coloured species with a distinctive white, orange–red, green and black pattern on the back, each area of which is clearly delineated. The skin on the back is very smooth, but that of the grey belly is a little bit rough. The snout is rounded, the eyes are prominent but the tympani are inconspicuous. The limbs are short and robust and the digits of the hand have large tips and the hind feet are webbed. Adapted for both underground and climbing lifestyles, the Malagasy rainbow frog has horny tubercles on the underside of the hind feet to help with burrowing, and claws on the forefeet for ...

Lungless Salamander
Plethodontidae, or lungless salamanders, are a family of salamanders. Most species are native to the Western Hemisphere, from British Columbia to Brazil, although a few species are found in Sardinia, Europe south of the Alps, and South Korea. In terms of number of species, they are by far the largest group of salamanders. Biology Adult lungless salamanders have four limbs, with four toes on the fore limbs, and usually with five on the hind limbs. Within many species, mating and reproduction occur solely on land. Accordingly, many species also lack an aquatic larval stage, a phenomenon known as direct development in which the offspring hatch as fully-formed, miniature adults. Direct development is correlated with changes in the developmental characteristics of plethodontids compared to other families of salamanders including increases in egg size and duration of embryonic development. Additionally, the evolutionary loss of the aquatic larval stage is related to a diminishing dep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Table Mountain Ghost Frog
Rose's ghost frog (''Heleophryne rosei''), or Table Mountain ghost frog, is a species of frog in the family Heleophrynidae endemic to South Africa. It is a medium-sized species with purple or brown blotches on a pale green background and large discs on its fingers and toes. It has a very restricted range, being only known from the slopes of parts of Table Mountain. The tadpoles live in permanent streams but these are in danger of drying up because of the establishment of pine plantations. Because of its small range and changes in its habitat, this frog is listed as critically endangered by the International Union for Conservation of Nature. Description This is a moderately sized frog, with the larger female up to and the smaller male up to in length. The coloration of adults is striking, often a pale green background with purple to brown blotches. The fingers and toes have large, triangular terminal discs. A rudimentary thumb is present as a distinct inner metacarpal tubercl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boulengerula Niedeni
''Boulengerula niedeni'', the Sagalla caecilian, is a worm-like amphibian first described in 2005. The species was described from a specimen discovered on Sagala Hill, an isolated mountain block of the Taita Hills in Kenya, and is not known from other areas. Little of the original forest remains on Sagalla Hill, but the species seems to adapt to human disturbance associated with small-scale farming activities; it is not found in the eucalyptus plantations that cover much of the hill. Because of the small range of this species, it is as of 2013 listed as endangered on the IUCN Red List of Threatened Species, while previously from 2006 been listed as critically endangered. It has been listed as one of the top-10 "focal species" in 2008 by the Evolutionarily Distinct and Globally Endangered (EDGE) project. Description The Sagalla caecilian is a caecilian, a highly unusual group of amphibians characterized by an elongated, limbless, externally segmented body, closely resembling ...

Gardiner's Seychelles Frog
Gardiner's Seychelles frog (''Sechellophryne gardineri'') is a small frog of the family Sooglossidae and endemic to the Seychelles. It is named after John Stanley Gardiner, English zoologist and oceanographer. Description Gardiner's frog is one of the smallest frogs in the world, reaching a maximum length of . Newly hatched frogs measure in length. Adult males are long. It is brown in color, and has a dark stripe running from its mouth to its legs. This frog is notable for its ability to hear despite the absence of a middle ear cavity. Research has shown that the species is able to use its mouth cavity to amplify sound and transmit it to the inner ear,as explained by co-author '' Jean-François Aubry''. Ecology and behavior Gardiner's frog is a terrestrial frog, feeding on small invertebrates including mites, sciarid larvae, ants, and amphipods. It is restricted to the high- and mid-altitude areas of Mahé and Silhouette Islands of the Seychelles group. This is unusual am ...

Hellbender
The hellbender (''Cryptobranchus alleganiensis''), also known as the hellbender salamander, is a species of aquatic giant salamander endemic to the eastern and central United States. It is the largest salamander in North America. A member of the family Cryptobranchidae, the hellbender is the only extant member of the genus ''Cryptobranchus''. Other closely related salamanders in the same family are in the genus ''Andrias'', which contains the Japanese and Chinese giant salamanders. The hellbender, which is much larger than all other salamanders in its geographic range, employs an unusual means of respiration (which involves cutaneous gas exchange through capillaries found in its dorsoventral skin folds), and fills a particular niche—both as a predator and prey—in its ecosystem, which either it or its ancestors have occupied for around 65 million years. The species is listed as Vulnerable on the IUCN Red List of Threatened Species. Etymology The origin of the name "hellbender ...
