Paratarsotomus Macropalpis
''Paratarsotomus macropalpis'' is a species of mite belonging to the family Erythracaridae. The mite is endemic to Southern California and is usually observed darting amongst sidewalks and in rocky areas. Earlier classified as belonging to genus '' Tarsotomus'', it was reclassified in 1999, along with four other species, to genus ''Paratarsotomus''. It is quite small—0.7 mm—but has been recorded as the world's fastest land animal relative to body length. __TOC__ Discovery A specimen was first collected by William A. Hilton from beneath stones in Claremont, California. It was classified and named as ''Tarsotomus macropalpis'' by Nathan Banks whose report in 1916 was Speed record The mite has been recorded at a speed of 322 body lengths per second (). This is far in excess of the previous record holder, the Australian tiger beetle '' Rivacindela hudsoni'', the fastest insect in the world relative to body size, which has been recorded at or 171 body lengths per second. ...

Palp
Pedipalps (commonly shortened to palps or palpi) are the secondary pair of forward appendages among chelicerates – a group of arthropods including spiders, scorpions, horseshoe crabs, and sea spiders. The pedipalps are lateral to the chelicerae ("jaws") and anterior to the first pair of walking legs. Overview Pedipalps are composed of six segments or articles. From the proximal end (where they are attached to the body) to the distal, they are: the coxa, the trochanter, the femur, the short patella, the tibia, and the tarsus. In spiders, the coxae frequently have extensions called maxillae or gnathobases, which function as mouth parts with or without some contribution from the coxae of the anterior legs. The limbs themselves may be simple tactile organs outwardly resembling the legs, as in spiders, or chelate weapons (pincers) of great size, as in scorpions. The pedipalps of Solifugae are covered in setae, but have not been studied in detail. Comparative studies of pedipal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nathan Banks
Nathan Banks (April 13, 1868 – January 24, 1953) was an American entomologist noted for his work on Neuroptera, Megaloptera, Hymenoptera, and Acarina (mites). He started work on mites in 1880 with the USDA. In 1909 he reported many Costa Rican species with several new species saying "During the past few years the writer has received large series of spiders and daddy-longlegs from Costa Rica for identification". In 1915 he authored the first comprehensive English handbook on mites: ''A Treatise on the Acarina, Or Mites'' (Smithsonian Institution, Proceedings Of The United States National Museum, 1905, 114 pages). Banks left the USDA in 1916 to work at the Museum of Comparative Zoology (MCZ) where he did further work on Hymenoptera, Arachnida and Neuroptera. He was elected a Fellow of the American Academy of Arts and Sciences in 1922. In 1924, he spent about two months in Panama, through kindness of Dr. Thomas Barbour and in company with Dr. William Morton Wheeler, W.M. Wheeler. ...

Endemic Fauna Of California
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomi ...

Biomimetics
Biomimetics or biomimicry is the emulation of the models, systems, and elements of nature for the purpose of solving complex human problems. The terms "biomimetics" and "biomimicry" are derived from (''bios''), life, and μίμησις (''mimesis, mīmēsis''), imitation, from μιμεῖσθαι (''mīmeisthai''), to imitate, from μῖμος (''mimos''), actor. A closely related field is bionics. Nature has gone through evolution over the 3.8 billion years since life is estimated to have appeared on the Earth. It has evolved species with high performance using commonly found materials. Surfaces of solids interact with other surfaces and the environment and derive the properties of materials. Biological materials are highly organized from the molecular to the nano-, micro-, and macroscales, often in a hierarchical manner with intricate nanoarchitecture that ultimately makes up a myriad of different functional elements. Properties of materials and surfaces result from a complex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robot
A robot is a machine—especially one Computer program, programmable by a computer—capable of carrying out a complex series of actions Automation, automatically. A robot can be guided by an external control device, or the robot control, control may be embedded within. Robots may be constructed to evoke Humanoid robot, human form, but most robots are task-performing machines, designed with an emphasis on stark functionality, rather than expressive aesthetics. Robots can be autonomous robot, autonomous or semi-autonomous and range from humanoids such as Honda's ''Advanced Step in Innovative Mobility'' (ASIMO) and TOSY's ''TOSY Ping Pong Playing Robot'' (TOPIO) to industrial robots, robot-assisted surgery, medical operating robots, patient assist robots, dog therapy robots, collectively programmed Swarm robotics, ''swarm'' robots, UAV drones such as General Atomics MQ-1 Predator, and even microscopic Nanorobotics, nanorobots.

Metre Per Second Squared
The metre per second squared or metre per square second is the unit of acceleration in the International System of Units (SI). As a derived unit, it is composed from the SI base units of length, the metre, and of time, the second. Its symbol is written in several forms as m/s2, m·s−2 or ms−2, , or less commonly, as (m/s)/s. As acceleration, the unit is interpreted physically as change in velocity or speed per time interval, i.e. metre per second per second and is treated as a vector quantity. Example When an object experiences a constant acceleration of one metre per second squared (1 m/s2) from a state of rest, it achieves the speed of 5 m/s after 5 seconds and 10 m/s after 10 seconds. The average acceleration ''a'' can be calculated by dividing the speed ''v'' (m/s) by the time ''t'' (s), so the average acceleration in the first example would be calculated: :a = \frac = \frac = 1\text = 1\text^2.

It reaches at the shoulder, and the head-and-body length is between . Adults weigh between . The cheetah is capable of running at ; it has evolved specialized adaptations for speed, including a light build, long thin legs and a long tail. The cheetah was first Species description, described in the late 18th century. Four subspecies are recognised today that are native to Africa and central Iran. An African subspecies was Cheetah reintroduction in India, introduced to India in 2022. It is now distributed mainly in small, fragmented populations in northwestern, East Africa, eastern and southern Africa and central Iran.

Rivacindela Hudsoni
''Rivacindela hudsoni'' is an Australian species of the family Cicindelinae or "tiger beetle" and is the fastest running insect. The genus ''Rivacindela'' is contentiously treated as a subgenus of the broader ''Cicindela'' and are typically found in salty habitats such as dry salt lakes and salt streams. The species was discovered in South Australia and described in 1997, with an adult form of approximately 20–21mm in length and a running speed of 2.49 m/s, or 120 body lengths per second. Tiger beetles are a unique species of beetles due to their widespread global distribution and abundance. With over 2300 species of tiger beetles, the diversity in their coloration, behavior, and ability to thrive in varying Natural environment, environments has led many scientists to analyze more about their background, history, taxonomy, and ecological relationships with other organisms. Tiger beetles have an interesting classification: they are a unique species within the ''Beetle, Col ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tiger Beetle
Tiger beetles are a family of beetles, Cicindelidae, known for their aggressive predatory habits and running speed. The fastest known species of tiger beetle, '' Rivacindela hudsoni'', can run at a speed of , or about 125 body lengths per second. As of 2005, about 2,600 species and subspecies were known, with the richest diversity in the Oriental (Indo-Malayan) region, followed by the Neotropics. While historically treated as a subfamily of ground beetles (Carabidae) under the name Cicindelinae, several studies since 2020 indicated that they should be treated as a family, the Cicindelidae, which are a sister group to Carabidae within the Adephaga. Description Tiger beetles often have large bulging eyes, long, slender legs and large curved mandibles. All are predatory, both as adults and as larvae. The genus '' Cicindela'' has a cosmopolitan distribution. Other well-known genera include '' Tetracha'', '' Omus'', '' Amblycheila'' and '' Manticora''. While members of the genus ''C ...

Apical (anatomy)
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, '' Terminolog ...

Tibia
The tibia (; : tibiae or tibias), also known as the shinbone or shankbone, is the larger, stronger, and anterior (frontal) of the two Leg bones, bones in the leg below the knee in vertebrates (the other being the fibula, behind and to the outside of the tibia); it connects the knee with the ankle bones, ankle. The tibia is found on the anatomical terms of location#Medial, medial side of the leg next to the fibula and closer to the median plane. The tibia is connected to the fibula by the interosseous membrane of leg, forming a type of fibrous joint called a syndesmosis with very little movement. The tibia is named for the flute ''aulos, tibia''. It is the second largest bone in the human body, after the femur. The leg bones are the strongest long bones as they support the rest of the body. Structure In human anatomy, the tibia is the second largest bone next to the femur. As in other vertebrates the tibia is one of two bones in the lower leg, the other being the fibula, and is a ...

Femur
The femur (; : femurs or femora ), or thigh bone is the only long bone, bone in the thigh — the region of the lower limb between the hip and the knee. In many quadrupeds, four-legged animals the femur is the upper bone of the hindleg. The Femoral head, top of the femur fits into a socket in the pelvis called the hip joint, and the bottom of the femur connects to the shinbone (tibia) and kneecap (patella) to form the knee. In humans the femur is the largest and thickest bone in the body. Structure The femur is the only bone in the upper Human leg, leg. The two femurs converge Anatomical terms of location, medially toward the knees, where they articulate with the Anatomical terms of location, proximal ends of the tibiae. The angle at which the femora converge is an important factor in determining the femoral-tibial angle. In females, thicker pelvic bones cause the femora to converge more than in males.
