Uraeotyphlidae
''Uraeotyphlus'' is a genus of caecilians in the family Ichthyophiidae. There are seven species in this genus, all of which are endemic to the Western Ghats of southwestern India. Previously, the genus has also been placed in its own Monotypic#Zoology, monotypic family Uraeotyphlidae. Description ''Uraeotyphlus'' are relatively small sized caecilians ranging from to in length. Unlike the more 'advanced' caecilians, members of this genus have a true tail with vertebrae, and their skull has a relatively complex structure. However, unlike the more 'primitive' caecilians, the mouth is recessed below the snout, there are no tertiary annuli, and the tentacular opening are far forward of the eyes, and below the nostril. The pattern of annulation among species of ''Uraeotyphlus'' falls into two clear types based on the differentiation of primary and higher-order annuli, and the number of annular divisions per vertebra and whether this varies along the body. This difference is reflect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Uraeotyphlus Gansi
''Uraeotyphlus gansi'', the Gansi caecilian, is a rare species of caecilian, endemic to the Western Ghats of India. It was discovered in the Kaakkaachi-Naalumukku area of the Kalakkad Mundanthurai Tiger Reserve. ''U. gansi'' was named after Carl Gans (1923–2009), a renowned herpetologist from Texas. According to Albert Rajendran, Research Department of Zoology, St. John's College, Palayamkottai, Rajendran spotted the species, along with his collaborator David J. Gower of the Natural History Museum A natural history museum or museum of natural history is a scientific institution with natural history scientific collection, collections that include current and historical records of animals, plants, Fungus, fungi, ecosystems, geology, paleo ..., London, and two other experts in caecilians. He came across this limbless amphibian in the Kaakkaachi-Naalumukku areas during his study of the burrowing uropeltid (shield-tailed) snakes of the Western Ghats. References {{ ...

Uraeotyphlus Oommeni
''Uraeotyphlus oommeni'', sometimes known as the Oommen's caecilian, Oommen's Uraeotyphlus, or Bonnacord caecilian, is a species of caecilian in the family Ichthyophiidae. Within ''Uraeotyphlus'', it belongs to the '' U. malabaricus'' group showing no obvious external differentiation between primary and higher-order annuli. This species is endemic to the Western Ghats and only known from its type locality, Bonaccord, Thiruvananthapuram district, southern Kerala. Very little is known about this species known only from a single specimen collected from an imprecise location. Etymology The specific name ''oommeni'' honours Oommen V. Oommen, professor of zoology at the University of Kerala. Description The holotype is a mature female measuring in total length and wide at mid-body. There are 207 (left side) and 214 (right side) annuli, without clear external differentiation between primary and higher-order annuli. The body is strongly dorsoventrally compressed. The head is smal ... [...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 ...

Skull
The skull, or cranium, is typically a bony enclosure around the brain of a vertebrate. In some fish, and amphibians, the skull is of cartilage. The skull is at the head end of the vertebrate. In the human, the skull comprises two prominent parts: the neurocranium and the facial skeleton, which evolved from the first pharyngeal arch. The skull forms the frontmost portion of the axial skeleton and is a product of cephalization and vesicular enlargement of the brain, with several special senses structures such as the eyes, ears, nose, tongue and, in fish, specialized tactile organs such as barbels near the mouth. The skull is composed of three types of bone: cranial bones, facial bones and ossicles, which is made up of a number of fused flat and irregular bones. The cranial bones are joined at firm fibrous junctions called sutures and contains many foramina, fossae, processes, and sinuses. In zoology, the openings in the skull are called fenestrae, the most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monotypic
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical syste ...

India
India, officially the Republic of India, is a country in South Asia. It is the List of countries and dependencies by area, seventh-largest country by area; the List of countries by population (United Nations), most populous country since 2023; and, since its independence in 1947, the world's most populous democracy. Bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast, it shares land borders with Pakistan to the west; China, Nepal, and Bhutan to the north; and Bangladesh and Myanmar to the east. In the Indian Ocean, India is near Sri Lanka and the Maldives; its Andaman and Nicobar Islands share a maritime border with Thailand, Myanmar, and Indonesia.

Ichthyophiidae
The Ichthyophiidae are the family of Asiatic tailed caecilians or fish caecilians found in South and Southeast Asia as well as southernmost China. They are primitive caecilians, lacking many of the derived characters found in the other families. For example, their mouths are not recessed underneath their heads, they possess tails, and they have numerous scales on their bodies. However, they have two sets of muscles for closing the jaw, a feature unique to caecilians, but absent in the related family Rhinatrematidae. They lay their eggs in cavities in moist soil, where they hatch into larvae that seek out streams or underground seepages, before metamorphosing into adults. Some evidence indicates the females may protect their eggs until they hatch.

Endemic
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or bec ...
