Spider
Spiders ( order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every land habitat. , 50,356 spider species in 132 families have been recorded by taxonomists. However, there has been debate among scientists about how families should be classified, with over 20 different classifications proposed since 1900. Anatomically, spiders (as with all arachnids) differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindrical pedicel, however, as there is currently neither paleontological nor embryological evidence that spiders ever had ...

Tetrablemma
''Tetrablemma'' is a widespread genus of armored spiders first described by Octavius Pickard-Cambridge in 1873. It only has four eyes; an unusual trait for spiders, found only here and in some species of ''Caponiidae'', though the two are not closely related. The eyes are large, but unequal in size, closely grouped around the center of the prosoma that rises in a somewhat of a cone shape from the abdomen. They have four closely positioned spinnerets enclosed in a corneous casing. Species , the World Spider Catalog accepted the following species: *''Tetrablemma alaus'' Burger, Harvey & Stevens, 2010 – Australia (Western Australia) *'' Tetrablemma alterum'' Roewer, 1963 – Micronesia *'' Tetrablemma benoiti'' (Brignoli, 1978) – Seychelles *'' Tetrablemma brevidens'' Tong & Li, 2008 – China *'' Tetrablemma brignolii'' Lehtinen, 1981 – India *'' Tetrablemma deccanense'' (Tikader, 1976) – India *'' Tetrablemma extorre'' Shear, 1978 – Trinidad *''Tetrablemma helenense'' ...

Sri Lanka
Sri Lanka (, ; si, ශ්රී ලංකා, Śrī Laṅkā, translit-std=ISO (); ta, இலங்கை, Ilaṅkai, translit-std=ISO ()), formerly known as Ceylon and officially the Democratic Socialist Republic of Sri Lanka, is an island country in South Asia. It lies in the Indian Ocean, southwest of the Bay of Bengal, and southeast of the Arabian Sea; it is separated from the Indian subcontinent by the Gulf of Mannar and the Palk Strait. Sri Lanka shares a maritime border with India and Maldives. Sri Jayawardenepura Kotte is its legislative capital, and Colombo is its largest city and financial centre. Sri Lanka has a population of around 22 million (2020) and is a multinational state, home to diverse cultures, languages, and ethnicities. The Sinhalese are the majority of the nation's population. The Tamils, who are a large minority group, have also played an influential role in the island's history. Other long established groups include the Moors, the Burghers ...

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. ... Coalescence dates for most non-European populations average to between 73–55 ka.", "Modern human beings—''Homo sapiens''—originated in Africa. Then, int ...

Tetrablemmidae
Tetrablemmidae, sometimes called armored spiders, is a family of tropical araneomorph spiders first described by Octavius Pickard-Cambridge in 1873. It contains 126 described species in 29 genera from southeast Asia, with a few that occur in Africa and Central and South America. Pacullidae was incorporated into this family in 1981, but was later restored as a separate family in a 2016 phylogenetic study. Most species have been collected from litter and soil, including that of epiphytes. Some live in caves and show typical adaptations of cave spiders, such as loss of eyes and weak sclerotization. Members of '' Tetrablemma'' only have four eyes, a trait in spiders only found in these and certain members of Caponiidae. Genera , the World Spider Catalog accepts the following genera: *'' Ablemma'' Roewer, 1963 — Papua New Guinea, Asia *'' Afroblemma'' Lehtinen, 1981 — Angola, Tanzania, Congo *'' Anansia'' Lehtinen, 1981 — Angola *'' Bacillemma'' Deeleman-Reinhold, 1993 — Tha ...

Endemic Fauna Of Sri Lanka
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] |
