Octavius Pickard-Cambridge
Octavius Pickard-Cambridge Fellow of the Royal Society, FRS (3 November 1828 – 9 March 1917) was an England, English clergyman and zoologist. He was a keen arachnologist who described and named more than 900 species of spider. Life and work Pickard-Cambridge was born in Bloxworth rectory, Dorset, the fifth son of Rev. George Pickard, rector and squire of Bloxworth: the family changed its name to Pickard-Cambridge in 1848 after receiving the property left behind by a relative, Charles Owen Cambridge, of Whitminster House in Gloucestershire. Octavius was tutored at home by the poet William Barnes, after failing to receive admission to Winchester College. He also learned to play the violin from Sidney Smith. He then studied law in London before theology at the Durham University, University of Durham. He was very active and made many friends in this period. He served as steward at steeplechases and presided over the college choral society. In 1857 he presented the Pickard-Camb ...

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 ...

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 ...

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 ...

Psechridae
Psechridae is a family (biology), family of Araneomorphae, araneomorph spiders with about 70 species in two genera. These are among the biggest cribellate spiders with body lengths up to and funnel webs more than in diameter. The family belongs to the RTA clade of spiders because they all have a Retrolateral Tibial Apophysis on the male pedipalp. A recent phylogenetic analysis places Psechridae as close relatives of the lynx spiders, wolf spiders, and nursery web spiders. They feature several characteristics normally found in ecribellate spiders, for example brood care behavior, and a colulus with no apparent function. They have greatly elongated legs, with the last element being very flexible. Female ''Psechrus'' carry their egg-sac in the chelicerae, similar to their relatives, the ecribellate Pisauridae. Members of ''Psechrus'' construct horizontal webs lace webs, while ''Fecenia'' construct pseudo-orbs, similar to orb webs of Orbiculariae spiders in an example of Convergen ...

Arthropods Of Sri Lanka
Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished 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. Arthropods are bilaterally symmetrical and their body possesses an external skeleton. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. Some species have wings. They are an extremely diverse group, with up to 10 million species. The haemocoel, an arthropod's internal cavity, through which its haemolymph – analogue of blood – circulates, accommodates its interior organs; it has an open circulatory system. Like their exteriors, the internal organs of arthropods are generally built of repeated segments. Their nervous system is "ladder ...
