Sooglossidae
Sooglossidae, the Seychelles frogs or Seychelles Island frogs, are a family of frogs found on the Seychelles Islands. Until recently, this family was believed to include the genera '' Sechellophryne'', '' Nesomantis'' and '' Sooglossus'', but following a major revision of amphibians in 2006, the genus ''Nesomantis'' was named a junior synonym of ''Sooglossus''. Their closest relatives are the purple frogs ( Nasikabatrachidae) of India. Description All Sooglossidae species are relatively small terrestrial frogs, about in length, hiding under fallen leaves or in rock crevices. They are unusual for the neobatrachials, in that they undertake inguinal amplexus, a primitive version of amplexus. They lay their eggs on moist ground, rather than in water. Several species lack tadpoles, with the eggs hatching directly into froglets. The tadpoles of '' S. sechellensis'' are carried, abnormally, on the backs of the female frogs until metamorphosis. There is no fossil record for the family. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thomasset's Seychelles Frog
Thomasset's Seychelles frog or Thomasset's frog (''Sooglossus thomasseti'') is a species of frog in the family Sooglossidae. It is endemic to Seychelles. There are two known populations: one on Silhouette Island and one on Mahé Island. The natural habitats of this frog are subtropical or tropical moist lowland forests, subtropical or tropical moist montane forests, rivers, and intermittent rivers. Eggs are laid among rocks and hatch into miniature adults, bypassing a larval stage. The species is threatened by habitat loss Habitat destruction (also termed habitat loss or habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved elsewhere, or are dead, leading to a decrease .... Genetic analysis indicates that the two populations of this species are distinct from each other and are possibly even separate species. It has thus been proposed that both populations be considered evolutiona ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Seychelles Frog
The Seychelles frog (''Sooglossus sechellensis'') is a species of frog endemic to Mahé, Silhouette and Praslin islands in the Seychelles. It inhabits the floor of damp rainforest at altitudes from to above sea level. Higher altitude sites are considered to be more climatically stable and more suitable. The species is present in Morne Seychellois National Park, Silhouette National Park and Praslin National Park. The reproductive biology of this species is unusual. Eggs are laid on the ground and guarded until they hatch. The tadpoles are thereafter carried on one of their parent's backs. The IUCN assessed the species as "Endangered" in 2013. Although it is locally common, it has a small area of occupancy (about 29 km2), a severely fragmented habitat and distribution, and a declining population, particularly at lower altitudes. It is threatened by habitat degradation due to fire and invasive species (the tree ''Cinnamomum verum ''Cinnamomum verum'' ( synonym ''Cinna ...

George Albert Boulenger
George Albert Boulenger (19 October 1858 – 23 November 1937) was a Belgian-British zoologist who described and gave scientific names to over 2,000 new animal species, chiefly fish, reptiles, and amphibians. Boulenger was also an active botanist during the last 30 years of his life, especially in the study of roses. Life Boulenger was born in Brussels, Belgium, the only son of Gustave Boulenger, a Belgian public notary, and Juliette Piérart, from Valenciennes. He graduated in 1876 from the Free University of Brussels (1834–1969), Free University of Brussels with a degree in natural sciences, and worked for a while at the Royal Belgian Institute of Natural Sciences, Brussels, as an assistant naturalist studying amphibians, reptiles, and fishes. He also made frequent visits during this time to the ''National Museum of Natural History (France), Muséum national d'Histoire naturelle'' in Paris and the Natural History Museum, London, British Museum in London.

Frog
A frog is any member of a diverse and largely semiaquatic group of short-bodied, tailless amphibian vertebrates composing the order (biology), order Anura (coming from the Ancient Greek , literally 'without tail'). Frog species with rough skin texture due to wart-like parotoid glands tend to be called toads, but the distinction between frogs and toads is informal and purely cosmetic, not from taxonomy (biology), taxonomy or evolutionary history. Frogs are widely distributed, ranging from the tropics to subarctic regions, but the greatest concentration of species diversity is in tropical rainforest and associated wetlands. They account for around 88% of extant amphibian species, and are one of the five most diverse vertebrate orders. The oldest fossil "proto-frog" ''Triadobatrachus'' is known from the Early Triassic of Madagascar (250Myr, million years ago), but molecular clock, molecular clock dating suggests their divergent evolution, divergence from other amphibians may exte ...

Seychelles
Seychelles (, ; ), officially the Republic of Seychelles (; Seychellois Creole: ), is an island country and archipelagic state consisting of 155 islands (as per the Constitution) in the Indian Ocean. Its capital and largest city, Victoria, Seychelles, Victoria, is east of mainland Africa. Nearby island countries and territories include the Comoros, Madagascar, Mauritius, and the French Fifth Republic, French overseas departments and regions of France, overseas departments of Mayotte and Réunion to the south; and the Chagos Archipelago to the east. Seychelles is the list of African countries by area, smallest country in Africa as well as the list of African countries by population, least populated sovereign African country, with an estimated population of 100,600 in 2022. Seychelles was uninhabited prior to being encountered by Europeans in the 16th century. It faced competing French and British interests until it came under full British control in the early 19th century. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphibian Species Of The World
''Amphibian Species of the World 6.2: An Online Reference'' (ASW) is a herpetology database. It lists the names of frogs, salamanders and other amphibians, which scientists first described each species and what year, and the animal's known range. The American Museum of Natural History hosts ''Amphibian Species of the World'', which is updated by herpetologist Darrel Frost. As of 2024, it contained more than 8700 species. History The Association of Systematics Collections (ASC) started this project in 1978 because the Convention on Trade in Endangered Species of Fauna and Flora (CITES) needed a database for animals. (The ASC later changed its name to Natural Science Collections Alliance.) The ASC's Stephen R. Edwards wrote ''Mammal Species of the World'' first and started ''Amphibian Species of the World'' second. Edwards decided to write about living amphibians because Richard G. Zweifel had just composed a large list of amphibian names and because experts from the Universi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphibian Genera
Amphibians are ectothermic, anamniote, anamniotic, tetrapod, four-limbed vertebrate animals that constitute the class (biology), class Amphibia. In its broadest sense, it is a paraphyletic group encompassing all Tetrapod, tetrapods, but excluding the amniotes (tetrapods with an amniotic membrane, such as modern reptiles, birds and mammals). All extant taxon, extant (living) amphibians belong to the monophyletic subclass (biology), subclass Lissamphibia, with three living order (biology), orders: Anura (frogs and toads), Urodela (salamanders), and Gymnophiona (caecilians). Evolved to be mostly semiaquatic, amphibians have adapted to inhabit a wide variety of habitats, with most species living in freshwater ecosystem, freshwater, wetland or terrestrial ecosystems (such as riparian woodland, fossorial and even arboreal habitats). Their biological life cycle, life cycle typically starts out as aquatic animal, aquatic larvae with gills known as tadpoles, but some species have devel ...
