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. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sechellophryne Gardineri
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 amo ...

Nesomantis
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. 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 evolutionary significant units An evolutionarily significant unit (ESU) is a population of organisms that is considered distinct for purposes of conservation. Delineating ESUs is important when considering conservation action. This term can apply to any species, s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sechellophryne Pipilodryas
The Seychelles palm frog (''Sechellophryne pipilodryas'') is a species of frog that is endemic to Silhouette Island in the Seychelles. It is closely related to Gardiner's frog, ''Sechellophryne gardineri''. The Seychelles palm frog inhabits forests higher than above sea level and is closely associated with the palm ''Phoenicophorium borsigianum'' (another Seychelles endemic); most individuals are found in axils of the palm. It is the most arboreal of the Sooglossidae. As a result, the palm frog is the most recent species of the family to have been discovered (in 2000). The reproductive biology of this species is unknown, but it is presumed to involve direct development, i.e. eggs that hatch directly into froglets.

Nasikabatrachus
''Nasikabatrachus'' is a genus of frogs. It is presently treated as the only genus in the family Nasikabatrachidae, though previously it was included in the family Sooglossidae. Two species are recognized, ''Nasikabatrachus bhupathi'' and ''Nasikabatrachus sahyadrensis'', both endemic to southwestern India. Both Nasikabatrachidae and Sooglossidae are thought to be the only extant families of the superfamily Sooglossoidea. With its closest relatives in the Seychelles, ''Nasikabatrachus'' is thought to have evolved separately since the end of the Cretaceous. Its discovery added to the evidence that Madagascar and the Seychelles separated from the India India, officially the Republic of India (Hindi: ), is a country in South Asia. It is the seventh-largest country by area, the second-most populous country, and the most populous democracy in the world.

Frogs
A frog is any member of a diverse and largely carnivorous group of short-bodied, tailless amphibians composing the 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 dating suggests their split from other amphibians may extend further back to the Permian, 265 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 or evolutionary history. An adult frog has a stout body, protruding eyes, anteriorly-attached tongue, limbs folded underneath, and no tail (the tail of tailed frogs is an ex ...

Neobatrachia
The Neobatrachia (New Latin ''neo-'' ("new") + ''batrachia'' ("frogs")) are a suborder of the Anura, the order of frogs and toads. This suborder is the most advanced and apomorphic of the three anuran suborders alive today, hence its name, which literally means "new frogs" (from the hellenic words ''neo'', meaning "new" and ''batrachia'', meaning "frogs"). It is also by far the largest of the three; its more than 5,000 different species make up over 96% of all living anurans. The differentiation between Archaeobatrachia, Mesobatrachia, and Neobatrachia is based primarily on anatomic differences, especially the skeletal structure, as well as several visible characteristics and behaviors. Systematics Separating the Anura into the Archaeo-, Meso- and Neobatrachia is somewhat controversial; as more research is done and more knowledge is gained, it is becoming even less clear, because many characteristics used for this differentiation apply to more than one group.

Amplexus
Amplexus (Latin "embrace") is a type of mating behavior exhibited by some externally fertilizing species (chiefly amphibians and horseshoe crabs) in which a male grasps a female with his front legs as part of the mating process, and at the same time or with some time delay, he fertilizes the eggs, as they are released from the female's body. In amphibians, females may be grasped by the head, waist, or armpits, and the type of amplexus is characteristic of some taxonomic groups. Amplexus involves direct contact between male and female, distinguished from other forms of external fertilization, such as broadcast spawning, where sperm and eggs are freely shed into water without direct contact by individuals. In order for amplexus to be initiated, male frogs must first find a mate by attracting one through calls, typically in the evening. Once a male has successfully attracted a mate, the process of amplexus begins, while the unsuccessful males are forced to continue their search fo ...

Seychelles Frog
The Seychelles frog (''Sooglossus sechellensis'') is a species of frog endemic to Mahé, Seychelles, Mahé, Silhouette Island, 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'' and t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
