Ichthyophis Glutinosus
''Ichthyophis glutinosus'', the Ceylon caecilian or common yellow-banded caecilian, is a species of caecilian in the family Ichthyophiidae Endemism, endemic to Sri Lanka. Its natural habitats are moist tropical and subtropical forests and pastures. Description The Ceylon caecilian grows to about long and resembles a large earthworm. The skin is formed into over 300 transverse folds which give the caecilian the appearance of being segmented. The head has a rounded snout and a pair of extensible tentacles near the mouth, rather closer to the eyes than to the nostrils. The colour of this caecilian is steely blue above and pale yellow underneath, with a yellow band running along either side of the body. Distribution and habitat The Ceylon caecilian is endemic to southwestern and central Sri Lanka. It has also been reported to occur in northeastern India, but more likely this sighting referred to a different species. It lives in burrows in damp earth or leaf litter in subtropical or ...

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lateral Line
The lateral line, also called the lateral line organ (LLO), is a system of sensory organs found in fish, used to detect movement, vibration, and pressure gradients in the surrounding water. The sensory ability is achieved via modified epithelial cells, known as hair cells, which respond to displacement caused by motion and transduce these signals into electrical impulses via excitatory synapses. Lateral lines serve an important role in schooling behavior, predation, and orientation. Fish can use their lateral line system to follow the vortices produced by fleeing prey. Lateral lines are usually visible as faint lines of pores running lengthwise down each side, from the vicinity of the gill covers to the base of the tail. In some species, the receptive organs of the lateral line have been modified to function as electroreceptors, which are organs used to detect electrical impulses, and as such, these systems remain closely linked. Most amphibian larvae and some fully aquatic adult ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphibians Of Sri Lanka
Sri Lanka is a tropical island situated close to the southern tip of India. It is situated in the middle of Indian Ocean. Because of being an island, Sri Lanka has rich endemic terrestrial and freshwater fauna, including vertebrates and several invertebrates. Amphibian *Phylum: Chordata *Class: Amphibia Amphibians are ectothermic vertebrates of the class Amphibia. They have soft glandular skin and live in all habitats of the world except for the ice caps. They complete an amphibious lifestyle where larval stages live in water and adults live on or closer to land. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators. Sri Lanka is host to over 120 species of amphibians, of which over 90 species are endemic to the country. The 85% of endemicity ratio makes Sri Lanka the country which has the highest amphibian endemism in Asia. During the past decade many more new amphibians have been found in Sri Lanka. The first amphibian review ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxa Named By Carl Linnaeus
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 int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphibians Described In 1758
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 ...

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 ...

Udawatta Kele Sanctuary
Udawattakele Forest Reserve often spelled as Udawatta Kele, is a historic forest reserve on a hill-ridge in the city of Kandy. It is 104 hectares (257 acres) large. During the days of the Kandyan kingdom, Udawattakele was known as "Uda Wasala Watta" in Sinhalese meaning "the garden above the royal palace". The sanctuary is famous for its extensive avifauna. The reserve also contains a great variety of plant species, especially lianas, shrubs and small trees. There are several giant lianas. Many of small and medium size mammals that inhabit Sri Lanka can be seen here. Several kinds of snakes and other reptiles might be seen. Udawattakele was designated as a forest reserve in 1856, and it became a sanctuary in 1938. The Sri Lanka Forest Department has two offices in the reserve, one of which (at the southeastern entrance) has a nature education centre with a display of pictures, posters, stuffed animals, etc. Being easily accessible and containing a variety of flora and fauna the fore ...

Knuckles Mountain Range
The Knuckles Mountain Range lies in central Sri Lanka, in the Districts of Matale and Kandy. The range takes its name from a series of recumbent folds and peaks in the west of the massif which resemble the knuckles of clenched fist when viewed from certain locations in the Kandy District. Whilst this name was assigned by early British surveyors, the Sinhalese residents have traditionally referred to the area as ''Dumbara Kanduvetiya'' meaning Mist-laden Mountain Range. The higher montane area is often robed in thick layers of cloud. In addition to its aesthetic value, the range is of great scientific interest. It is a climatic microcosm of the rest of Sri Lanka as the conditions of all the climatic zones in the country are exhibited in the massif. At higher elevations there is a series of isolated cloud forests, harbouring a variety of flora and fauna. Although the range constitutes approximately 0.03% of the island's total area, it is home to a significantly higher proportion o ...

Sinharaja Forest Reserve
Sinharaja Forest Reserve is a forest reserve and a biodiversity hotspot in Sri Lanka. It is of international significance and has been designated a Biosphere Reserve and World Heritage Site by UNESCO. According to International Union for Conservation of Nature (IUCN), Sinharaja is the country's last viable area of primary tropical rainforest. More than 60% of the trees are endemic and many of them are considered rare. 50% of Sri Lankan's endemics species of animals (especially butterfly, amphibians, birds, snakes and fish species). It is home to 95% endemic birds. The hilly virgin rainforest, part of the Sri Lanka lowland rain forests ecoregion, was saved from the worst of commercial logging by its inaccessibility, and was designated a World Biosphere Reserve in 1978 and a World Heritage Site in 1988. Because of the dense vegetation, wildlife is not as easily seen as at dry-zone national parks such as Yala. There are about 3 elephants, and 15 or so leopards. The most common l ...

IUCN Red List Of Threatened Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the International Union for Conservation of Nature, IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction.

Metamorphosis
Metamorphosis is a biological process by which an animal physically develops including birth or hatching, involving a conspicuous and relatively abrupt change in the animal's body structure through cell growth and differentiation. Some insects, fish, amphibians, mollusks, crustaceans, cnidarians, echinoderms, and tunicates undergo metamorphosis, which is often accompanied by a change of nutrition source or behavior. Animals can be divided into species that undergo complete metamorphosis (" holometaboly"), incomplete metamorphosis ("hemimetaboly"), or no metamorphosis (" ametaboly"). Scientific usage of the term is technically precise, and it is not applied to general aspects of cell growth, including rapid growth spurts. Generally organisms with a larva stage undergo metamorphosis, and during metamorphosis the organism loses larval characteristics. References to "metamorphosis" in mammals are imprecise and only colloquial, but historically idealist ideas of transformation ...

Gill
A gill () is a respiratory organ that many aquatic organisms use to extract dissolved oxygen from water and to excrete carbon dioxide. The gills of some species, such as hermit crabs, have adapted to allow respiration on land provided they are kept moist. The microscopic structure of a gill presents a large surface area to the external environment. Branchia (pl. branchiae) is the zoologists' name for gills (from Ancient Greek ). With the exception of some aquatic insects, the filaments and lamellae (folds) contain blood or coelomic fluid, from which gases are exchanged through the thin walls. The blood carries oxygen to other parts of the body. Carbon dioxide passes from the blood through the thin gill tissue into the water. Gills or gill-like organs, located in different parts of the body, are found in various groups of aquatic animals, including mollusks, crustaceans, insects, fish, and amphibians. Semiterrestrial marine animals such as crabs and mudskippers have gill cham ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
