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] |

Heleophrynoidea
Heleophrynidae is a family of frogs, commonly known as ghost frogs. They are thought to be the most basal group in the Neobatrachia. The family consists of two genera, ''Heleophryne'' and ''Hadromophryne'', with seven species. Ghost frogs live in swift-moving mountain streams in South Africa. The common name of "ghost frogs" may have been coined because of their occurrence in Skeleton Gorge. Taxonomy The ghost frogs were formerly thought to be closely related to the Sooglossidae of the Seychelles (which are now thought to be a sister group to Ranoidea), or to the Australian Myobatrachidae, which are now thought to be a sister group to Hyloidea. In contrast, more recent taxonomic studies place them as being the most basal extant members of the Neobatrachia and having no close relatives, having diverged from the rest of the Neobatrachia during the Early Cretaceous, about 140 million years ago.

Royal Ghost Frog
The royal ghost frog (''Heleophryne regis''), also known as the southern ghost frog or Cape ghost frog, is a species of frog in the family Heleophrynidae. It is endemic to South Africa, and lives in fast-moving streams. Description Ghost frogs get their name as one of the six species found in Skeleton Gorge (on Table Mountain), South Africa. The underside of the body, including the jaw, has small hooks, which help the frogs climb over wet rocks near their habitats. The frogs measure in length. It is in the same size range as Hewitt's ghost frog, but is smaller than Purcell's ghost frog. The top side of its body is brown with yellow spots, and the underside is white. The limbs are plain-colored, and flesh-colored underneath. Their tadpoles take up to two years to develop fully. The call of the royal ghost frog is a harsh, creaking sound, given at around one call per second. Habitat All species of ghost frogs are endemic to the southern tip of Africa. Its natural habitat is fynbos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eastern Ghost Frog
The eastern ghost frog (''Heleophryne orientalis'') is a species of frog in the family Heleophrynidae. It is endemic to Western Cape Province, South Africa. Its natural habitats are forest patches surrounded by mountain fynbos heathland. Adult frogs live near slow- to swift flowing perennial mountain streams in isolated canyons. They are typical sit-and-wait predators which hunt at night near to the splash zone of the mountain streams. Breeding takes place in fast-flowing, perennial streams. Clutches of 120–190 eggs are laid extra aquatic under moss-covered rocks. Their 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 i ...s take two years to complete their development and possess unique larval features such as the appearance of both the admandibular and the adrostral cartil ...

Purcell's Ghost Frog
The Purcell's ghost frog (''Heleophryne purcelli'') is a species of frog in the family Heleophrynidae. It is endemic to Western Cape Province, South Africa. Its natural habitat is fynbos heathland. Breeding takes place in perennial streams. Their 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 i ...s take two years to develop fully. Purcell's ghost frog is a common species that is not significantly threatened, but is locally affected by introduced species.

Hewitt's Ghost Frog
The Hewitt's ghost frog (''Heleophryne hewitti'') 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. Hewitt's ghost frog has a very restricted range: it is known from in total five rivers, four in the Elandsberg mountains and one in the Cockscomb mountains. Only small remnants of fynbos survive within its range, and it is threatened by habitat loss Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby ... caused by afforestation, fires, erosion, siltation of stream ...

EDGE Species
Evolutionarily Distinct and Globally Endangered (EDGE) species are animal species which have a high 'EDGE score', a metric combining endangered conservation status with the genetic distinctiveness of the particular taxon. Distinctive species have few closely related species, and EDGE species are often the only surviving member of their genus or even higher taxonomic rank. The extinction of such species would therefore represent a disproportionate loss of unique evolutionary history and biodiversity. Some EDGE species, such as elephants and pandas, are well-known and already receive considerable conservation attention, but many others, such as the vaquita (the world's rarest cetacean) the bumblebee bat (arguably the world's smallest mammal) and the egg-laying long-beaked echidnas, are highly threatened yet remain poorly understood, and are frequently overlooked by existing conservation frameworks. The Zoological Society of London launched the EDGE of Existence Programme in 2007 to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cederberg Ghost Frog
The Cederberg mountains are located near Clanwilliam, approximately 300 km north of Cape Town, South Africa at about . The mountain range is named after the endangered Clanwilliam cedar (''Widdringtonia wallichii''), which is a tree endemic to the area. The mountains are noted for dramatic rock formations and San rock art. The Cederberg Wilderness Area is administered by CapeNature. ''Cederberg'' is now the generally accepted spelling for the area, which combines the English (Cedarberg) and Afrikaans (Sederberg) variants. Geography and climate The Cederberg mountains extend about 50 km north–south by 20 km east–west. They are bordered on the west by the Sandveld, the north by the Pakhuis Mountains, the east by the Springbok Flats and the south by the Kouebokkeveld Mountains and the Skurweberge. The main access road, the N7, runs to the west of the range. The nearest towns are Citrusdal to the southwest and Clanwilliam to the north. The area is spars ...

Philip Lutley Sclater
Philip Lutley Sclater (4 November 1829 – 27 June 1913) was an English lawyer and zoologist. In zoology, he was an expert ornithologist, and identified the main zoogeographic regions of the world. He was Secretary of the Zoological Society of London for 42 years, from 1860–1902. Early life Sclater was born at Tangier Park, in Wootton St Lawrence, Hampshire, where his father William Lutley Sclater had a country house. George Sclater-Booth, 1st Baron Basing was Philip's elder brother. Philip grew up at Hoddington House where he took an early interest in birds. He was educated in school at Twyford and at thirteen went to Winchester College and later Corpus Christi College, Oxford where he studied scientific ornithology under Hugh Edwin Strickland. In 1851 he began to study law and was admitted a Fellow of Corpus Christi College. In 1856 he travelled to America and visited Lake Superior and the upper St. Croix River, canoeing down it to the Mississippi. Sclater wrote ab ...
