Salticidae
Jumping spiders are a group of spiders that constitute the family (biology), family Salticidae. , this family contained over 600 species description, described genus, genera and over 6,000 described species, making it the largest family of spiderscomprising 13% of spider species. Jumping spiders have some of the best visual perception, vision among arthropods — being capable of stereoptic color vision — and use sight in courtship, hunting, and navigation. Although they normally move unobtrusively and fairly slowly, most species are capable of very agile jumps, notably when hunting, but sometimes in response to sudden threats or crossing long gaps. Both their book lungs and Invertebrate trachea, tracheal system are well-developed, and they use both systems (bimodal breathing). Jumping spiders are generally recognized by their eye pattern. All jumping spiders have four pairs of eyes, with the Anatomical terms of location, anterior median pair (the two front middle eyes) being pa ...

Phidippus Regius
''Phidippus regius'', commonly known as the regal jumper, is a species of jumping spider found in parts of the United States and the Caribbean. It is the largest species of jumping spider in eastern North America. Description Adult male ''P. regius'' measure long on average, but can range between long. The first pair of legs, which are disproportionately larger in large males, have an alternating black and white fringe. The opisthosoma is black with several white markings on the dorsum - a basal band, a central triangular spot, and two posterior oval spots. The chelicerae are large and iridescent green-blue-violet in color, with a tubercle on each. Adult female ''P. regius'' measure long on average, but can range between long. They may exhibit white or orange markings on the opisthosoma similar to the white markings seen in males, but the rest of the body is largely covered with scales which may be brown, orange, tan, gray, or a combination of those colors.

Phidippus
''Phidippus'' is a genus in the family Salticidae (jumping spiders). Some of the largest jumping spiders inhabit this genus, and many species are characterized by their brilliant, iridescent green chelicerae. ''Phidippus'' is distributed almost exclusively in North America, with the exception of two exported species (''Phidippus audax'' and ''Phidippus regius'').Edwards, G. B. (2004). pp. vii, 4–6. , there were about 80 described species in the genus. Species previously described in ''Phidippus'' which are found in India and Bangladesh do not belong in this genus. Name The genus name is likely derived from Cicero's speech ''Pro Rege Deiotaro'' (Speech in Behalf of King Deiotarus): Phidippus was a slave who was physician to King Deiotaros. Literally, the word means "one who spares horses" in Ancient Greek.Ubick ''et al.'' 2005 Species , the World Spider Catalog accepted the following species: * '' Phidippus adonis'' Edwards, 2004 – Mexico * '' Phidippus adumbratus'' Ger ...

Hyllus (spider)
''Hyllus'' is a genus of the spider family Salticidae (jumping spiders). Most species occur in Africa and Madagascar, with many in Australasia and north to India. ''H. insularis'' is found in Greece and Iran, but it is considered misplaced in this genus,Logunov 2001 and is now ''Evarcha insularis''. Description They are medium to large spiders, commonly mistaken by those in the genus ''Evarcha''. They are usually stout, hairy and dully colored. They usually have horns at the top of the Glossary of spider terms, median eyes formed by long bristles. They have a rounded carapace, which is larger than the eye field. Those in the genus ''Evarcha'' are usually smaller and their carapace is thinner. Name Hyllus was the son of Heracles and Deianira in Greek mythology. Species , the World Spider Catalog accepted these species: *''Hyllus acutus'' (John Blackwall, Blackwall, 1877) – Comoro Islands, Seychelles *''Hyllus aegyptiacus'' (Denis, 1947) – Egypt *''Hyllus africanus'' Lesse ...

Spider
Spiders (order (biology), order Araneae) are air-breathing arthropods that have eight limbs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude spider silk, silk. They are the largest order of arachnids and rank seventh in total species diversity among all Order (biology), orders of organisms. Spiders are found worldwide on every continent except Antarctica, and have become established in nearly every land habitat. , 53,034 spider species in 136 Family (biology), families have been recorded by Taxonomy (biology), taxonomists. However, there has been debate among scientists about how families should be classified, with over 20 different classifications proposed since 1900. Anatomy, Anatomically, spiders (as with all arachnids) differ from other arthropods in that the usual body segmentation (biology), segments are fused into two Tagma (biology), tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindr ...

Philaeus
''Philaeus'' is a genus of jumping spiders that was first described by Tamerlan Thorell in 1869. ''Philaeus maoniuensis'' was moved to genus '' Yllenus'' in 2003. Species it contains seven species with a wide distribution. Most species are from the Mediterranean and West Africa, but single species are known from Guatemala and the Galapagos Islands: *'' Philaeus chrysops'' (Poda, 1761) (type) – Europe, North Africa to Middle East, Turkey, Caucasus, Russia (Europe to Far East), Iran, Central Asia, Afghanistan, China, Mongolia, Korea *'' Philaeus corrugatulus'' Strand, 1917 – Algeria *'' Philaeus daoxianensis'' Peng, Gong & Kim, 2000 – China *'' Philaeus fallax'' (Lucas, 1846) – Algeria *'' Philaeus raribarbis'' Denis, 1955 – Morocco *'' Philaeus ruber'' Peckham & Peckham, 1885 – Guatemala *'' Philaeus steudeli'' Strand, 1906 – West Africa West Africa, also known as Western Africa, is the westernmost region of Africa.

Platycryptus Undatus
''Platycryptus undatus'', also called the tan or familiar jumping spider, is a species of jumping spider (family Salticidae), native to North America.A guide to some of Ontario's spiders by Cole, Noah. Ontario Nature Magazine. 2017. pp. 60-61 Description Tan jumping spiders can be identified by their mottled tan coloration, thin bodies and chevron patterning on their abdomens. The tan jumping spider's thin body allows them to hide themselves under the loosened bark of trees and in other tight places. The prominent chevron-like pattern on their abdomens serves to break up their visual profile and make them more difficult to distinguish on mottled surfaces. Females of this species are between 10 and 13 mm in body length, and males rang ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anatomical Terms Of Location
Standard anatomical terms of location are used to describe unambiguously the anatomy of humans and other animals. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and axes. The meaning of terms that are used can change depending on whether a vertebrate is a biped or a quadruped, due to the difference in the neuraxis, or if an invertebrate is a non-bilaterian. A non-bilaterian has no anterior or posterior surface for example but can still have a descriptor used such as proximal or distal in relation to a body part that is nearest to, or furthest from its middle. International organisations have determined vocabularies that are often used as standards for subdisciplines of anatomy. For example, '' Termi ...

Paleocene
The Paleocene ( ), or Palaeocene, is a geological epoch (geology), epoch that lasted from about 66 to 56 mya (unit), million years ago (mya). It is the first epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name is a combination of the Ancient Greek ''palaiós'' meaning "old" and the Eocene Epoch (which succeeds the Paleocene), translating to "the old part of the Eocene". The epoch is bracketed by two major events in Earth's history. The K–Pg extinction event, brought on by an asteroid impact (Chicxulub impact) and possibly volcanism (Deccan Traps), marked the beginning of the Paleocene and killed off 75% of species, most famously the non-avian dinosaurs. The end of the epoch was marked by the Paleocene–Eocene Thermal Maximum (PETM), which was a major climatic event wherein about 2,500–4,500 gigatons of carbon were released into the atmosphere and ocean systems, causing a spike in global temperatures and ocean acidification. ...

Spider Silk
Spider silk is a protein fibre or silk spun by spiders. Spiders use silk to make webs or other structures that function as adhesive traps to catch prey, to entangle and restrain prey before biting, to transmit tactile information, or as nests or cocoons to protect their offspring. They can use the silk to suspend themselves from height, to float through the air, or to glide away from predators. Most spiders vary the thickness and adhesiveness of their silk according to its use. In some cases, spiders may use silk as a food source. While methods have been developed to collect silk from a spider by force, gathering silk from many spiders is more difficult than from silk-spinning organisms such as silkworms. All spiders produce silk, although some spiders do not make webs. Silk is tied to courtship and mating. Silk produced by females provides a transmission channel for male vibratory courtship signals, while webs and draglines provide a substrate for female sex pheromone ...
