Ichthyophis Tricolor
''Ichthyophis tricolor'', the three-colored caecilian or Maddatorai caecilian, is an amphibian endemic to the Western Ghats, India. Its taxonomic status is unclear, including its relationship with ''Ichthyophis beddomei'' and the possibility of cryptic species. Description Adult measure in total length, including the long tail. Its body is violet-brown, with a yellow lateral stripe from the lips to the tip of the tail, slightly wider and unbroken at the neck. A broad, white ventral stripe is present. Its snout is slightly projecting, the eyes are distinct, and the tentacles are placed closer to the eye at the edge of the upper lip. Habitat and conservation ''Ichthyophis tricolor'' is a subterranean species associated with wet, semi-evergreen tropical forests, but also agricultural areas and rubber plantations. It occurs from near sea level up to asl. It is an oviparous Oviparous animals are animals that lay their eggs, with little or no other embryonic development with ...

Nelson Annandale
Thomas Nelson Annandale CIE FRSE (15 June 1876, in Edinburgh – 10 April 1924, in Calcutta) was a British zoologist, entomologist, anthropologist, and herpetologist. He was the founding director of the Zoological Survey of India. Life The eldest son of Thomas Annandale, the regius professor of clinical surgery at the University of Edinburgh. His maternal grandfather was a publisher, William Nelson. Thomas was educated at Rugby School, Balliol College, Oxford where he studied under Ray Lankester and E. B. Tylor (doing better in anthropology than zoology), and at the University of Edinburgh where he studied anthropology, receiving a D.Sc. (1905). As a student he made visits to Iceland and the Faeroe Islands. In 1899 he travelled with Herbert C. Robinson as part of the Skeat Expedition to the northern part of the Malay Peninsula. Annandale went to India in 1904 as Deputy Superintendent under A.W. Alcock of the Natural History Section of the Indian Museum. He was a deputy dir ...

Amphibian
Amphibians are tetrapod, four-limbed and ectothermic vertebrates of the Class (biology), class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial animal, 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 re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Ichthyophis Beddomei
''Ichthyophis beddomei'' is a species of caecilian in the family Ichthyophiidae. This species is distributed widely in the Western Ghats in southern India. The nominal species might be a composite of several cryptic species. It is also known as the yellow-striped caecilian, Beddome's caecilian, or Nilgherries caecilian. Description Adults measure in total length, including the long tail. The body is dark violet-brown, becoming light brown ventrally. A yellow lateral stripe runs from the head to the tail tip. The stripe becomes slightly wider at the neck. The upper lip and lower jaw are also yellow in colour. The eyes are distinct. The tentacles are placed very close to the lip and almost equidistant from the eyes and nostrils. The nostrils at the tip of the snout are visible from above. The upper jaw slightly overhangs the lower jaw. Habitat and conservation ''Ichthyophis beddomei'' is a subterranean species associated with leaf-litter, humus, and soil substrates. It lives ...

Above Sea Level
Height above mean sea level is a measure of the vertical distance (height, elevation or altitude) of a location in reference to a historic mean sea level taken as a vertical datum. In geodesy, it is formalized as ''orthometric heights''. The combination of unit of measurement and the physical quantity (height) is called "metres above mean sea level" in the metric system, while in United States customary and imperial units it would be called "feet above mean sea level". Mean sea levels are affected by climate change and other factors and change over time. For this and other reasons, recorded measurements of elevation above sea level at a reference time in history might differ from the actual elevation of a given location over sea level at a given moment. Uses Metres above sea level is the standard measurement of the elevation or altitude of: * Geographic locations such as towns, mountains and other landmarks. * The top of buildings and other structures. * Flying objects such ...

Oviparous
Oviparous animals are animals that lay their eggs, with little or no other embryonic development within the mother. This is the reproductive method of most fish, amphibians, most reptiles, and all pterosaurs, dinosaurs (including birds), and monotremes. In traditional usage, most insects (one being ''Culex pipiens'', or the common house mosquito), molluscs, and arachnids are also described as oviparous. Modes of reproduction The traditional modes of reproduction include oviparity, taken to be the ancestral condition, traditionally where either unfertilised oocytes or fertilised eggs are spawned, and viviparity traditionally including any mechanism where young are born live, or where the development of the young is supported by either parent in or on any part of their body. However, the biologist Thierry Lodé recently divided the traditional category of oviparous reproduction into two modes that he named ovuliparity and (true) oviparity respectively. He distinguished the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ichthyophis
''Ichthyophis'' is a genus of caecilians (limbless amphibians, sometimes called the Asian caecilians) found in Southeast Asia, the southern Philippines The Philippines (; fil, Pilipinas, links=no), officially the Republic of the Philippines ( fil, Republika ng Pilipinas, links=no), * bik, Republika kan Filipinas * ceb, Republika sa Pilipinas * cbk, República de Filipinas * hil, Republ ..., and the western Indo-Australian Archipelago. In Sri Lanka, three species occur. All are found in almost all habitats, but are known to prefer moist ones. The most common is ''Ichthyophis glutinosus'', which is found in almost all altitudes; the others are ''I. orthoplicatus'', which is found in similar habitat to ''I. glutinosus'', but will not be found in lowlands below above sea level; and ''I. pseudangularis'', found in lowlands below ASL. A new species was recently discovered called '' Ichthyophis multicolor''. Species References * * AmphibiaWeb: Information on amphibia ...

Taxa Named By Nelson Annandale
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in '' Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
