Triped
Tripedalism (from the Latin tri = three + ped = foot) is locomotion by the use of three limbs. It has been said that parrots ( Psittaciformes) display tripedalism during climbing gaits, which was tested and proven in a 2022 paper on the subject, making parrots the only creatures to truly use tripedal forms of locomotion. Tripedal gaits were also observed by K. Hunt in primates. This is usually observed when the animal is using one limb to grasp a carried object and is thus a non-standard gait. Apart from climbing in parrots, there are no known animal behaviours where the same three extremities are routinely used to contact environmental supports, although the movement of some macropods such as kangaroos, which can alternate between resting their weight on their muscular tails and their two hind legs and hop on all three, may be an example of tripedal locomotion in animals. There are also the tripod fish. Several species of these fish rest on the ocean bottom on two rays from their ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Three-legged Crow
The three-legged (or tripedal) crow is a mythological creature in various mythologies and arts of East Asia. It is believed to inhabit and represent the Sun. Evidence of the earliest bird-Sun motif or totemic articles excavated around 5000 BCE. from the lower Yangtze River delta area. This bird-Sun totem heritage was observed in later Yangshao and Longshan cultures. Also, in Northeast Asia, artifacts of birds and phoenix observed to be a symbol of leadership was excavated to be around 5500 BCE in Xinle culture and later Hongshan culture from Liao river basin. The Chinese have several versions of crow and crow-Sun tales. But the most popular depiction and myth of the Sun crow is that of the Yangwu or Jinwu, the "golden crow". It has also been found figured on ancient coins from Lycia and Pamphylia. China In Chinese mythology and culture, the three-legged crow is called the sanzuwu (; Cantonese: ''sam1zuk1wu1''; Shanghainese: sae tsoh u) and is present in many myths. It is also ...

Macropodidae
Macropodidae is a family of marsupials that includes kangaroos, wallabies, tree-kangaroos, wallaroos, pademelons, quokkas, and several other groups. These genera are allied to the suborder Macropodiformes, containing other macropods, and are native to the Australian continent (the mainland and Tasmania), New Guinea and nearby islands. Description Although omnivorous kangaroos lived in the past, modern macropods are herbivorous. Some are browsers, but most are grazers and are equipped with appropriately specialised teeth for cropping and grinding up fibrous plants, in particular grasses and sedges. In general, macropods have a broad, straight row of cutting teeth at the front of the mouth, no canine teeth, and a gap before the molars. The molars are large and, unusually, do not appear all at once but a pair at a time at the back of the mouth as the animal ages, eventually becoming worn down by the tough, abrasive grasses and falling out. Like many Macropodiformes, e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bipedalism
Bipedalism is a form of terrestrial locomotion where an organism moves by means of its two rear limbs or legs. An animal or machine that usually moves in a bipedal manner is known as a biped , meaning 'two feet' (from Latin ''bis'' 'double' and ''pes'' 'foot'). Types of bipedal movement include walking, running, and hopping. Several groups of modern species are habitual bipeds whose normal method of locomotion is two-legged. In the Triassic period some groups of archosaurs (a group that includes crocodiles and dinosaurs) developed bipedalism; among the dinosaurs, all the early forms and many later groups were habitual or exclusive bipeds; the birds are members of a clade of exclusively bipedal dinosaurs, the theropods. Within mammals, habitual bipedalism has evolved multiple times, with the macropods, kangaroo rats and mice, springhare, hopping mice, pangolins and hominin apes ( australopithecines, including humans) as well as various other extinct groups evolving th ...

Species 8472
Species 8472 is a fictional extraterrestrial species in the science fiction television series '' Star Trek: Voyager''. Species 8472 is a designation given to them by the Borg. The multiplayer game ''Star Trek Online'' gives their proper name as Undine. When the USS ''Voyager'' made contact with them, Species 8472 were engaged in a war with one of Star Trek's perennial antagonists, the Borg. They are noted for being a tripedal and telepathic species and for their use of biotechnology. They originated from what is called fluidic space and fought a successful war against the Borg for a time. They made peace with the Federation by negotiations with Captain Kathryn Janeway of the Starfleet vessel USS Voyager in the later 24th century. ''Star Trek: Voyager'' Relevant episodes of '' Star Trek: Voyager'' in which Species 8472 appear include season 3 episode 26 (season finale) " Scorpion: Part 1" and season 4 episode 1 (season premiere) " Scorpion: Part 2", season 4 episode 16 "Prey", ...

Helhest
In Danish folklore, a helhest (Danish " Hel horse") is a three-legged horse associated with Hel. Various Danish phrases are recorded that refer to the horse. The Helhest is associated with death and illness, and it is mentioned in folklore as having been spotted in various locations in Denmark. Folklore The horse figures into a number of Danish phrases as recent as the 19th century, such as "''han går som en helhest''" ("he walks like a hel-horse") for a male who "blunders in noisily". The helhest is sometimes described as going "around the churchyard on his three legs, he fetches Death", and from Schleswig, a phrase is recorded that, in time of plague, "die (corrected by Grimm from ''der'') Hel rides about on a three-legged horse, destroying men".Grimm (1883:844). 19th century scholar Benjamin Thorpe connects the Danish phrase "he gave death a pack of oats" when an individual survives a near-fatal disease to notions of the Helhest, considering the oats either an offering or a br ...

Terrestrial Locomotion
Terrestrial locomotion has evolved as animals adapted from aquatic to terrestrial environments. Locomotion on land raises different problems than that in water, with reduced friction being replaced by the increased effects of gravity. As viewed from evolutionary taxonomy, there are three basic forms of animal locomotion in the terrestrial environment: * legged – moving by using appendages * limbless locomotion – moving without legs, primarily using the body itself as a propulsive structure. * rolling – rotating the body over the substrate Some terrains and terrestrial surfaces permit or demand alternative locomotive styles. A sliding component to locomotion becomes possible on slippery surfaces (such as ice and snow), where location is aided by potential energy, or on loose surfaces (such as sand or scree), where friction is low but purchase (traction) is difficult. Humans, especially, have adapted to sliding over terrestrial snowpack and terrestrial ice by means of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quadrupedalism
Quadrupedalism is a form of locomotion where four limbs are used to bear weight and move around. An animal or machine that usually maintains a four-legged posture and moves using all four limbs is said to be a quadruped (from Latin ''quattuor'' for "four", and ''pes'', ''pedis'' for "foot"). Quadruped animals are found among both vertebrates and invertebrates. Quadrupeds vs. tetrapods Although the words ‘quadruped’ and ‘tetrapod’ are both derived from terms meaning ‘four-footed’, they have distinct meanings. A tetrapod is any member of the taxonomic unit Tetrapoda (which is defined by descent from a specific four-limbed ancestor), whereas a quadruped actually uses four limbs for locomotion. Not all tetrapods are quadrupeds and not all entities that could be described as ‘quadrupedal’ are tetrapods. This last meaning includes certain artificial objects; almost all quadruped ''organisms'' are tetrapods (with the exception of some raptorial arthropods adapte ...

Dungeons & Dragons
''Dungeons & Dragons'' (commonly abbreviated as ''D&D'' or ''DnD'') is a fantasy tabletop role-playing game (RPG) originally designed by Gary Gygax and Dave Arneson. The game was first published in 1974 by Tactical Studies Rules, Inc. (TSR). It has been published by Wizards of the Coast (now a subsidiary of Hasbro) since 1997. The game was derived from miniature wargames, with a variation of the 1971 game ''Chainmail'' serving as the initial rule system. ''D&D'' publication is commonly recognized as the beginning of modern role-playing games and the role-playing game industry, and also deeply influenced video games, especially the role-playing video game genre. ''D&D'' departs from traditional wargaming by allowing each player to create their own character to play instead of a military formation. These characters embark upon adventures within a fantasy setting. A Dungeon Master (DM) serves as the game's referee and storyteller, while maintaining the setting in whi ...

The War Of The Worlds
''The War of the Worlds'' is a science fiction novel by English author H. G. Wells, first serialised in 1897 by ''Pearson's Magazine'' in the UK and by '' Cosmopolitan'' magazine in the US. The novel's first appearance in hardcover was in 1898 from publisher William Heinemann of London. Written between 1895 and 1897, it is one of the earliest stories to detail a conflict between mankind and an extra-terrestrial race. The novel is the first-person narrative of both an unnamed protagonist in Surrey and of his younger brother in London as southern England is invaded by Martians. The novel is one of the most commented-on works in the science fiction canon. The book's plot was similar to numerous works of invasion literature which were published around the same period, and has been variously interpreted as a commentary on the theory of evolution, British colonialism, and Victorian-era fears, superstitions and prejudices. Wells later noted that an inspiration for the p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
