Spider
Spiders (order Araneae) are air-breathing arthropods that have eight legs and chelicerae with fangs that inject venom. They are the largest order of arachnids and rank seventh in total species diversity among all other orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every habitat with the exceptions of air and sea colonization. , at least 45,700 spider species, and 113 families have been recorded by taxonomists. However, there has been dissension within the scientific community as to how all these families should be classified, as evidenced by the over 20 different classifications that have been proposed since 1900.
List of spiders of Sri Lanka
Sri Lanka is a tropical island situated close to the southern tip of India. The invertebrate fauna is as large as it is common to other regions of the world. There are about 2 million species of arthropods found in the world, and still it is counting. So many new species are discover up to this time also. So it is very complicated and difficult to summarize the exact number of species found within a certain region. The following list is about Spiders found in Sri Lanka. Spiders (order Araneae) are air-breathing arthropods that have eight legs and chelicerae with fangs that inject venom. Anatomically, spiders differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax and abdomen, and joined by a small, cylindrical pedicel.
Arthropod
An arthropod (from Greek ἄρθρον "arthron", "joint" and πούς "pous", "foot") is an invertebrate animal having an exoskeleton (external skeleton), a segmented body, and paired jointed appendages. Arthropods form the phylum Euarthropoda, which includes insects, arachnids, myriapods, and crustaceans. The term Arthropoda as originally proposed refers to a proposed grouping of Euarthropods and the phylum Onychophora. Arthropods are characterized by their jointed limbs and cuticle made of chitin, often mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages.
Spider behavior
Spider behavior refers to the range of behaviors and activities performed by spiders. Spiders are air-breathing arthropods that have eight legs and chelicerae with fangs that inject venom. They are the largest order of arachnids and rank seventh in total species diversity among all other groups of organisms which is reflected in their large diversity of behavior. Almost all known spider species are predators, mostly preying on insects and on other spiders, although a few species also take vertebrates such as frogs, lizards, fish, and even birds and bats. Spiders' guts are too narrow to take solids, and they liquidize their food by flooding it with digestive enzymes and grinding it with the bases of their pedipalps, as they do not have true jaws.
Chelicerata
The subphylum Chelicerata ( or ; New Latin, from French "chélicère", from Greek "khēlē" "claw, chela" and "kéras" "horn") constitutes one of the major subdivisions of the phylum Arthropoda. It contains the horseshoe crabs, sea spiders, and arachnids (including scorpions and spiders). The chelicerata originated as marine animals, possibly in the Cambrian period, but the first confirmed chelicerate fossils, eurypterids, date from in the Late Ordovician period. The surviving marine species include the four species of xiphosurans (horseshoe crabs), and possibly the 1,300 species of pycnogonids (sea spiders), if the latter are indeed chelicerates.
Hypoxia in fish
Fish are exposed to large oxygen fluctuations in their aquatic environment since the inherent properties of water can result in marked spatial and temporal differences in the concentration of oxygen (see oxygenation and underwater). Fish respond to hypoxia with varied behavioral, physiological, and cellular responses in order to maintain homeostasis and organism function in an oxygen-depleted environment. The biggest challenge fish face when exposed to low oxygen conditions is maintaining metabolic energy balance, as 95% of the oxygen consumed by fish is used for ATP production through the electron transport chain.
Arachnid
Arachnids are a class (Arachnida) of joint-legged invertebrate animals (arthropods), in the subphylum Chelicerata. All arachnids have eight legs, although the front pair of legs in some species has converted to a sensory function, while in other species, different appendages can grow large enough to take on the appearance of extra pairs of legs. The term is derived from the Greek word ("aráchnē"), from the myth of the hubristic human weaver Arachne who was turned into a spider. Spiders are the largest order in the class, which also includes scorpions, ticks, mites, harvestmen, and solifuges. Almost all extant arachnids are terrestrial, living mainly on land.

Beta diversity
In ecology, beta diversity (β-diversity or true beta diversity) is the ratio between regional and local species diversity. The term was introduced by R. H. Whittaker together with the terms alpha diversity (α-diversity) and gamma diversity (γ-diversity). The idea was that the total species diversity in a landscape (γ) is determined by two different things, the mean species diversity at the habitat level (α) and the differentiation among habitats (β). Other formulations for beta diversity include "absolute species turnover", "Whittaker's species turnover" and "proportional species turnover". Whittaker proposed several ways of quantifying differentiation, and subsequent generations of ecologists have invented more.

Dorien Bryant
Dorien Lamar Bryant (born March 19, 1985) is a former American football wide receiver. He went undrafted in the 2008 NFL Draft, but later signed with the Pittsburgh Steelers as a free agent. Bryant placed claim to 23 school and Big Ten Conference records during his time with the Boilermakers. Bryant attended Kingsway Regional High School, where he was ranked as ninth-best wide receiver and 75th-best player in the nation by Rivals.com. Bryant signed a letter of intent to attend Boston College in 2003. But he failed to qualify academically and spent the season at Fork Union Military Academy. He caught 30 passes that year, including nine touchdowns.
Bharat Ratna
The Bharat Ratna (; "Jewel of India") is the highest civilian award of the Republic of India. Instituted in 1954, the award is conferred "in recognition of exceptional service/performance of the highest order", without distinction of race, occupation, position, or sex. The award was originally limited to achievements in the arts, literature, science, and public services, but the government expanded the criteria to include "any field of human endeavour" in December 2011. The recommendations for the Bharat Ratna are made by the Prime Minister to the President, with a maximum of three nominees being awarded per year.
Barry Zito
Barry William Zito (born May 13, 1978) is an American former professional baseball pitcher and musician. He played 15 seasons in Major League Baseball (MLB) for the Oakland Athletics and San Francisco Giants. His pitching repertoire consisted of a curveball (his strikeout pitch), a four-seam fastball, a two-seam fastball, a circle changeup, and a cutter–slider. Zito attended the University of California, Santa Barbara, Los Angeles Pierce College, and the University of Southern California. Drafted three times while in college, Zito signed with the Athletics when they chose him in the first round of the 1999 MLB draft.
Yes (band)
Yes are an English rock band formed in London in 1968 by singer Jon Anderson, bassist Chris Squire, guitarist Peter Banks, keyboardist Tony Kaye, and drummer Bill Bruford. The band have undergone numerous formations throughout their history; nineteen musicians have been full-time members. Since June 2015, it has consisted of guitarist Steve Howe, drummer Alan White, keyboardist Geoff Downes, singer Jon Davison, and bassist Billy Sherwood, with no remaining founding members. Yes have explored several musical styles over the years, and are most notably regarded as progressive rock pioneers. Yes began in 1968, performing original songs and rearranged covers of rock, pop, blues and jazz songs, as evident on their first two albums.

Latrodectus
Latrodectus is a genus of spiders in the family Theridiidae, most of which are commonly known as widow spiders. The genus contains 31 recognized species distributed worldwide, including the North American black widows ("L. mactans", "L. hesperus", and "L. variolus"), the button spiders of Africa, and the Australian redback spider. Species vary widely in size. In most cases, the females are dark-coloured and readily identifiable by reddish markings on the abdomen, which are often (but not always) hourglass-shaped. While rarely fatal, or even serious, the venomous bite of these spiders is seen as particularly dangerous because of the neurotoxin latrotoxin, which causes the condition latrodectism, both named after the genus.
World of Eberron
The World of Eberron consists of a number of features for the Eberron campaign setting for the "Dungeons & Dragons" fantasy role-playing game. In the mythic past, the world was one great mass. The progenitor wyrms, the first and the greatest of dragon-kind, ruled all. The three most powerful - Siberys, Eberron, and Khyber - discovered the Prophecy. A world shattering struggle ensued. The battle split the world into three parts. Siberys became the glowing ring that surrounds the world and gave birth to the next generation of dragons. Khyber was bound to the darkest depths and spat out various fiends and demons.
Usage share of operating systems
The usage share of operating systems is an estimate of the percentage of computing devices that run each operating system at any particular time. This also approximates to the market share of those operating systems. Differences arise between shipments of devices by operating system and their usage share due to users changing or upgrading operating systems on devices, and the differing usage patterns and working lifetimes of various devices. There are three big personal computing platforms. Google claims over 2 billion users with Android while Microsoft has claimed over 1.4 billion users for Windows.
Snakebite
A snakebite is an injury caused by the bite of a snake, especially a venomous snake. A common symptom of a bite from a venomous snake is the presence of two puncture wounds from the animal's fangs. Sometimes venom injection from the bite may occur. This may result in redness, swelling, and severe pain at the area, which may take up to an hour to appear. Vomiting, trouble seeing, tingling of the limbs, and sweating may result. Most bites are on the hands or arms. Fear following a bite is common with symptoms of a racing heart and feeling faint. The venom may cause bleeding, kidney failure, a severe allergic reaction, tissue death around the bite, or breathing problems.
Western honey bee
The western honey bee or European honey bee ("Apis mellifera") is the most common of the 7–12 species of honey bee worldwide. The genus name "Apis" is Latin for "bee", and "mellifera" is the Latin for "honey-bearing", referring to the species' production of honey for the winter. Like all honey bees, the western honey bee is eusocial, creating colonies with a single fertile female (or "queen"), many sterile females or "workers," and small proportion of fertile males or "drones." Individual colonies can house tens of thousands of bees. Colony activities are organized by complex communication between individuals, through both pheromones and the dance language.

2011 All-Africa Games
The 10th All-Africa Games took place between September 3–18, 2011 in Maputo, Mozambique. Maputo's hosting marked the third time the Games was held in the southern part of the continent. In April 2005, Lusaka, Zambia was named the host of the 10th Games by the Supreme Council for Sport in Africa at a meeting in Algeria. In 2004, Ghana had indicated an interest in hosting the Games, but reportedly withdrew its bid. In December 2008, the Zambian government withdrew its offer to host the 2011 Games, due to a lack of funds. In April 2009, Mozambique stepped in to take on hosting duties. The following is a list of nations that participated in the 2011 All-Africa Games: The Maputo 2011 All Africa Games featured 20 sports, 2 of which also featured disabled events (athletics and swimming).
St. Luke Elementary School
St. Luke Elementary School is a Catholic primary school in Waterloo, Ontario. The school instructs students from Junior Kindergarten (JK) to the eighth grade. St. Luke opened in 2001 and is a part of the Waterloo Catholic District School Board. It is one of the feeder schools for St. David Catholic Secondary School. The school motto is "Rooted in the Love of Christ" and the school is named after Luke the Evangelist.

Inferior frontal gyrus
The inferior frontal gyrus is a part of the frontal gyrus of the frontal lobe (the yellow area of the human brain image to the right). It is labelled "gyrus frontalis inferior", its Latin name. In the yellow area, its superior border is the inferior frontal sulcus (which divides it from the "gyrus frontalis medius" in the yellow area), its inferior border the lateral fissure (which divides it from the "gyrus temporalis superior" in the green area), and its posterior border is the inferior precentral sulcus (in the yellow area). Above it is the middle frontal gyrus (the "gyrus frontalis medius"), behind it the precentral gyrus (the "gyrus praecentralis"), both gyri in the yellow area of the image.
Neoepicorsia claudiusalis
Neoepicorsia claudiusalis is a moth in the Crambidae family. It was described by Francis Walker in 1859. It is found in Brazil and Argentina.
Nihonium
Nihonium is a synthetic chemical element with symbol Nh and atomic number 113. It is extremely radioactive; its most stable known isotope, nihonium-286, has a half-life of about ten seconds. In the periodic table, nihonium is a p-block transactinide element. It is a member of the 7th period and is placed in group 13 on the periodic table, although it has not been confirmed to behave as the heavier homologue to thallium in that group. Nihonium was first reported to have been created in 2003 by a Russian–American collaboration at the Joint Institute for Nuclear Research (JINR) in Dubna, Russia, and in 2004 by a team of Japanese scientists at RIKEN.
Species
In biology, a species is the basic unit of biological classification and a taxonomic rank, as well as a unit of biodiversity, but it has proven difficult to find a satisfactory definition. Scientists and conservationists need a species definition which allows them to work, regardless of the theoretical difficulties. If as Linnaeus thought, species were fixed, there would be no problem, but evolutionary processes cause species to change continually, and to grade into one another. A species is often defined as the largest group of organisms in which two individuals can produce fertile offspring, typically by sexual reproduction.

Spider-Man's powers and equipment
The fictional Marvel Comics superhero Spider-Man, who debuted in 1962, is well known for his unique superhuman abilities as depicted in the comics and other media. He receives most of his powers when he is bitten by a radioactive common house spider. He uses his technical skill to develop equipment and weapons to complement his powers, and wears a number of costumes, many of which have special properties. When Peter Parker was bitten by an irradiated spider, radioactive mutagenic enzymes in the spider's venom quickly caused numerous body-wide changes. Immediately after the bite, he was granted his original powers: primarily superhuman strength, reflexes, and balance; the ability to cling tenaciously to most surfaces; and a subconscious ability to sense everything in his surroundings, which he called a "spider-sense".

This is a list of characters from the 1994 television series "Spider-Man." Peter Benjamin Parker (Christopher Daniel Barnes) is the main protagonist of the series. A one-time high school "science geek", Peter was the subject of much ridicule, especially at the hands of Flash Thompson. After his parents died in a plane crash, Peter lived with his Uncle Ben and Aunt May, who doted and worried endlessly about the reclusive boy suddenly placed in their midst. During a class field trip to see a demonstration of Neogenic radiation, carried on by Professor Farley Stillwell, a spider crawled into Stillwell's machine and became irradiated, biting Peter in the hand and granting him the proportionate abilities of a spider, including superhuman strength, durability, stamina, speed, agility, senses and a "Spider-Sense" that warned him of imminent danger.
Disability sport classification
Disability sports classification is a system that allows for fair competition between people with different types of disabilities. Historically, the process has been by two groups: specific disability type sport organizations that cover multiple sports, and specific sport organizations that cover multiple disability types including amputations, cerebral palsy, deafness, intellectual impairments, les autres and short stature, vision impairments, spinal cord injuries, and other disabilities not covered by these groups. Within specific disability types, some of the major organizations have been CPISRA has for cerebral palsy and head injuries, ISMWSF for spinal cord injuries, ISOD for orthopaedic conditions and amputees, INAS for people with intellectual disabilities, and IBSA for blind and vision impaired athletes.

According to Marvel, the storyline features every Spider-Man that has appeared in any media, all under attack by Morlun and his family, the Inheritors. Beginning in August 2014, the event was preceded by two new issues of the cancelled "Superior Spider-Man", issues of "Spider-Man 2099" and a five issue run of one shots-all under the "Edge of Spider-Verse" banner. Following the conclusion of the event in "Amazing Spider-Man" #14, some of the eponymous characters were featured in titles of their own including Silk of Earth-616 and Spider-Gwen, the Spider-Woman of Earth-65.
Doctor Octopus
Doctor Octopus (Otto Octavius) is a fictional character appearing in American comic books published by Marvel Comics. A highly intelligent mad scientist, Doctor Octopus is typically portrayed as a stocky, myopic man who utilizes four powerful, mechanical appendages, and is obsessed with proving his own genius and destroying the superhero Spider-Man. The character has appeared in numerous Spider-Man cartoons and video games, and is portrayed by Alfred Molina in the 2004 film "Spider-Man 2". In 2009, Doctor Octopus was ranked as IGN's 28th Greatest Comic Book Villain of All Time. His first brief appearance as the Superior Spider-Man was in "Daredevil" vol.

Nervous system
The nervous system is the part of an animal that coordinates its actions by transmitting signals to and from different parts of its body. The nervous system detects environmental changes that impact the body, then works in tandem with the endocrine system to respond to such events. Nervous tissue first arose in wormlike organisms about 550 to 600 million years ago. In vertebrates it consists of two main parts, the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS consists of the brain and spinal cord. The PNS consists mainly of nerves, which are enclosed bundles of the long fibers or axons, that connect the CNS to every other part of the body.

Anatomically, spiders differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax and abdomen, and joined by a small, cylindrical pedicel.
Neuroanatomy
Neuroanatomy is the study of the anatomy and stereotyped organization of nervous systems. In contrast to animals with radial symmetry, whose nervous system consists of a distributed network of cells, animals with bilateral symmetry have segregated, defined nervous systems. Their neuroanatomy is therefore better understood. In vertebrates, the nervous system is segregated into the internal structure of the brain and spinal cord (together called the central nervous system, or CNS) and the routes of the nerves that connect to the rest of the body (known as the peripheral nervous system, or PNS). The delineation of distinct structures and regions of the nervous system has been critical in investigating how it works.
Chelicerata
The subphylum Chelicerata ( or ; New Latin, from French "chélicère", from Greek "khēlē" "claw, chela" and "kéras" "horn") constitutes one of the major subdivisions of the phylum Arthropoda. It contains the horseshoe crabs, sea spiders, and arachnids (including scorpions and spiders). The chelicerata originated as marine animals, possibly in the Cambrian period, but the first confirmed chelicerate fossils, eurypterids, date from in the Late Ordovician period. The surviving marine species include the four species of xiphosurans (horseshoe crabs), and possibly the 1,300 species of pycnogonids (sea spiders), if the latter are indeed chelicerates.
Nerve net
A nerve net consists of interconnected neurons lacking a brain or any form of cephalization. While organisms with bilateral body symmetry are normally associated with a central nervous system, organisms with radial symmetry are associated with nerve nets. Nerve nets can be found in members of the Cnidaria, Ctenophora, and Echinodermata phyla, all of which are found in marine environments. Nerve nets can provide animals with the ability to sense objects through the use of the sensory neurons within the nerve net. The nerve net is the simplest form of a nervous system found in multicellular organisms.
Pavlov's typology
Pavlov's typology of higher nervous activity was the first systematic approach to the psychophysiology of individual differences. Ivan Pavlov's ideas of nervous system typology came from work with his dogs and his realization of individual differences. His observations of the dogs led to the idea of excitation and inhibition in the nervous system, and Pavlov theorized that the strength of these processes in the nervous system will determine whether the subject will have a strong or weak nervous system. This theory has influenced research in the field of social psychology and personality. Pavlov was a physiologist and his ideas on typology stemmed from his research on dogs and his research on the brain.
