rekordy: Fastest animals

Evidence: 100 • authority: 72

This is a list of the fastest animals in the world, by types of animal. The peregrine falcon is the fastest bird, and the fastest member of the animal kingdom, with a diving speed of over 300 km/h (190 mph). The fastest land animal is the cheetah, capable of running at speeds of up to 93–104 km/h (58–65 mph). Among the fastest animals in the sea is the black marlin, with uncertain and conflicting reports of recorded speeds. When drawing comparisons between different classes of animals, an alternative unit is sometimes used for organisms: body length per second. On this basis the 'fastest' organism on earth, relative to its body length, is the Southern Californian mite, Paratarsotomus macrop…

The cheetah (Acinonyx jubatus) is a species of large feline and the only living member of the genus Acinonyx. The cheetah is a pursuit predator and the fastest land animal, capable of running at 93–104 km/h (58–65 mph); it has evolved for speed, having powerful hindlimb muscles and a long lumbar spine. The cheetah has a tawny to creamy white or pale buff fur that is marked with evenly spaced, solid black spots. The head is small and rounded, with a short snout and black tear-like facial streaks. It has a height of 67–94 cm (2.20–3.08 ft) at the shoulder, and the head-and-body length is between 1.1 and 1.5 m (3 ft 7 in and 4 ft 11 in). Adults weigh between 21 and 65 kg (46 and 143 lb). The c…

Thomson's gazelle (Eudorcas thomsonii) is one of the best known species of gazelles. It is named after explorer Joseph Thomson and is sometimes referred to as a "tommie". It is considered by some to be a subspecies of the red-fronted gazelle and was formerly considered a member of the genus Gazella within the subgenus Eudorcas, before Eudorcas was elevated to genus status. Thomson's gazelles can be found in numbers exceeding 200,000 in Africa and are recognized as the most common type of gazelle in East Africa. A small antelope, the Thomson's gazelle is one of the fastest land animals, with estimated speeds up to 80 km/h (50 mph). Its main predator is the cheetah.

Three Characteristics of Cheetah Galloping Improve Running Performance Through Spinal Movement: A Modeling Study.. Cheetahs are the fastest land animal. Their galloping shows three characteristics: small vertical movement of their center of mass, small whole-body pitching movement, and large spine bending movement. We hypothesize that these characteristics lead to enhanced gait performance in cheetahs, including higher gait speed. In this study, we used a simple model with a spine joint and torsional spring, which emulate the body flexibility, to verify our hypothesis from a dynamic perspective. Specifically, we numerically searched periodic solutions and evaluated what extent each solution…

Chasing the cheetah: how field biomechanics has evolved to keep up with the fastest land animal. ABSTRACT Studying the motion of cheetahs – especially in the wild – is a technically challenging endeavour that pushes the limits of field biomechanics methodology. Consequently, it provides an interesting example of the scientific symbiosis that exists between experimental biology and the technological disciplines that support it. This article uses cheetah motion research as a basis to review the past, present and likely future of field biomechanics. Although the focus is on a specific animal, the methods and challenges discussed are broadly relevant to the study of terrestrial locomotion. We a…

Does sex matter in the cheetah? Insights into the skeletal muscle of the fastest land animal. ABSTRACT The cheetah is considered the fastest land animal, but studies on their skeletal muscle properties are scarce. Vastus lateralis biopsies, obtained from male and female cheetahs as well as humans, were analysed and compared for fibre type and size, and metabolism. Overall, cheetah muscle had predominantly type IIX fibres, which was confirmed by the myosin heavy chain isoform content (mean±s.d. type I: 17±8%, type IIA: 21±6%, type IIX: 62±12%), whereas human muscle contained predominantly type I and IIA fibres (type I: 49±14%, type IIA: 43±8%, type IIX: 7±7%). Cheetahs had smaller fibres tha…

Harnessing public perception of cheetah reintroduction in India to facilitate management through participatory decision-making.. Scientists, conservationists, and decision-makers are debating the restoration of the cheetah population in India, aiming to protect biodiversity and habitats, while several experts express concerns and question the benefits and drawbacks of the experiment. This study represents a pioneering effort to understand public perception of cheetah reintroduction in India, utilizing the tools of Natural Language Processing to evaluate widespread discourse from social media platforms (Twitter and Instagram) and online sources (Google and news media). Public attitudes and l…

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.

Sarah, also known as Sahara, (c. 2001–January 22, 2016) was a female South African cheetah (Acinonyx jubatus jubatus) that lived in the Cincinnati Zoo in Cincinnati, Ohio. Sarah was known as the world's fastest land mammal according to National Geographic magazine. She ran 100 meters in 5.95 seconds (more precisely, 5.9564 seconds and up to 61 miles an hour (98 km/h)) in 2012, when she was 11 years old. She died on January 22, 2016, at the supposed age of 15. Sarah came to the Cincinnati Zoo when she was six weeks old and was raised by Cathryn Hilker, who was the founder of the Zoo's Cat Ambassador Program. Sarah was one of the first cheetah cubs to be raised with a puppy companion, who was…
