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.

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, 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.

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.

Uraeotyphlus Narayani
''Uraeotyphlus narayani'', or Narayan's caecilian, is a species of caecilian endemic to the Western Ghats of India. Description This species is grey with a pale, flesh-coloured belly. A median greenish line runs between the chin and the tail. Its eyes are distinct with a white patch around them. The nostril are placed dorsally on the snout and visible from above. The tentacles are placed below the nostrils, not visible from above. The tip of the tail is whitish, and the snout tip and lower jaw are cream-coloured. It was described from Kottayam in Kerala, and has been reported from Karnataka.Bhatta, G. 1998. A field guide to the caecilians of the Western Ghats, India.

Amphibian Genera
Amphibians are four-limbed and ectothermic vertebrates of the class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in recent decades there has been a dramatic ...

Skull
The skull is a bone protective cavity for the brain. The skull is composed of four types of bone i.e., cranial bones, facial bones, ear ossicles and hyoid bone. However two parts are more prominent: the cranium and the mandible. In humans, these two parts are the neurocranium and the viscerocranium ( facial skeleton) that includes the mandible as its largest bone. The skull forms the anterior-most portion of the skeleton and is a product of cephalisation—housing the brain, and several sensory structures such as the eyes, ears, nose, and mouth. In humans these sensory structures are part of the facial skeleton. Functions of the skull include protection of the brain, fixing the distance between the eyes to allow stereoscopic vision, and fixing the position of the ears to enable sound localisation of the direction and distance of sounds. In some animals, such as horned ungulates (mammals with hooves), the skull also has a defensive function by providing the mount (on the front ...

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. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda. ...

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. 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 in the vicinity of Sri Lanka and the Maldives; its Andaman and Nicobar Islands share a maritime border with Thailand, Myanmar, and Indonesia. Modern humans arrived on the Indian subcontinent from Africa no later than 55,000 years ago., "Y-Chromosome and Mt-DNA data support the colonization of South Asia by modern humans originating in Africa. ...

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 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 be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
