Hare
Hares and jackrabbits are mammals belonging to the genus ''Lepus''. They are herbivores and live solitarily or in pairs. They nest in slight depressions called forms, and their young are able to fend for themselves shortly after birth. The genus includes the largest lagomorphs. Most are fast runners with long, powerful hind legs, and large ears that dissipate body heat. Hare species are native to Africa, Eurasia and North America. A hare less than one year old is called a "leveret". Members of the ''Lepus'' genus are considered true hares, distinguishing them from rabbits which make up the rest of the Leporidae family. However, there are five leporid species with "hare" in their common names which are not considered true hares: the hispid hare (''Caprolagus hispidus''), and four species known as red rock hares (''Pronolagus''). Conversely, several ''Lepus'' species are called "jackrabbits", but classed as hares rather than rabbits. The pet known as the Belgian hare is a domes ...

Mad As A March Hare
To be as "mad as a March hare" is an English language, English idiomatic phrase derived from the observed antics said to occur only in the March breeding season of the European hare (''Lepus europaeus''). The phrase is an allusion that can be used to refer to any other animal or human who behaves in the excitable and unpredictable manner of a March hare. Historical development of the idiom A long-held view is that the hare will behave strangely and excitedly throughout its breeding season, which, in Europe, peaks in the month of March. This odd behaviour includes boxing at other hares, jumping vertically for seemingly no reason and generally displaying abnormal behaviour. An early verbal record of this animal's strange behaviour occurred in about 1500, in the poem ''Blowbol's Test''First printed by W. C. Hazlitt in 1864, ''Remains of Early Popular Poetry of England'' where the original poet said: :''e'' :(Then they begin to swerve and to stare, And be as brainless as a March har ...

Scrub Hare
The scrub hare (''Lepus saxatilis'') is one of two species of hares found in southern Namibia, Mozambique, South Africa, Eswatini and Lesotho. Although it is listed as a least concern species, the population has been declining and is expected to decline by 20% over the next 100 years. Description The scrub hare has a very distinct coloration. On the Dorsal (anatomy), dorsal side of the hare, the fur is grizzled-gray with small black spots. The ventral side of the fur is all white. Scrub hares have a small, stubby tail with the topside being black and the underside being white. What makes ''Lepus saxatilis'' different from the other subspecies is the patch of red-brown fur it has behind its ears. They have long ears that are normally perched up that are gray, and together with its tail make it most visible when it is running from predators. The scrub hare has a very large range in its body size and body mass compared to most animals. Its length ranges from about , and its mass ran ...

Dominance (ethology)
In the zoological field of ethology, a dominance hierarchy (formerly and colloquially called a pecking order) is a type of social hierarchy that arises when members of animal social groups interact, creating a ranking system. Different types of interactions can result in dominance depending on the species, including ritualized displays of aggression or direct physical violence. In social living groups, members are likely to compete for access to limited resources and mating opportunities. Rather than fighting each time they meet, individuals of the same sex establish a relative rank, with higher-ranking individuals often gaining more access to resources and mates. Based on repetitive interactions, a social order is created that is subject to change each time a dominant animal is challenged by a subordinate one. Definitions Dominance is an individual's preferential access to resources over another based on coercive capacity based on strength, threat, and intimidation, comp ...

Alaskan Hare Skeleton
Alaska ( ) is a non-contiguous U.S. state on the northwest extremity of North America. Part of the Western United States region, it is one of the two non-contiguous U.S. states, alongside Hawaii. Alaska is also considered to be the northernmost, westernmost, and easternmost (the Aleutian Islands cross the 180th meridian into the eastern hemisphere) state in the United States. It borders the Canadian territory of Yukon and the province of British Columbia to the east. It shares a western maritime border, in the Bering Strait, with Russia's Chukotka Autonomous Okrug. The Chukchi and Beaufort Seas of the Arctic Ocean lie to the north, and the Pacific Ocean lies to the south. Technically, it is a semi-exclave of the U.S., and is the largest exclave in the world. Alaska is the largest U.S. state by area, comprising more total area than the following three largest states of Texas, California, and Montana combined, and is the seventh-largest subnational division in the worl ...

Cecotrope
Cecotropes (also caecotropes, cecotrophs, caecotrophs, cecal pellets, soft feces, or night feces) are a nutrient-filled package created in the gastrointestinal (GI) tract that is expelled and eaten by many animals (such as rabbits, guinea pigs, mice, hamsters, and chinchillas) to obtain more nutrients out of their food. When food passes through the GI tract the first time, the stomach and the small intestine digest the food material, which then moves into the colon, where the food particles are sorted by size. The smaller particles of fiber are moved into the cecum where they are fermented by microbes. This creates useable nutrients which are stored and expelled in cecotropes. The nutrients from the cecotropes are absorbed in the small intestine. The nutrients gained from cecotrophy include short-chain fatty acids, vitamin B, sodium, potassium, amino acids, and protein. Lagomorphs (a grouping including rabbits, hares, and pikas) are perhaps the most well-known for producing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cecum
The cecum ( caecum, ; plural ceca or caeca, ) is a pouch within the peritoneum that is considered to be the beginning of the large intestine. It is typically located on the right side of the body (the same side of the body as the appendix (anatomy), appendix, to which it is joined). The term stems from the Latin ''wikt:caecus, caecus'', meaning "blindness, blind". It receives chyme from the ileum, and connects to the ascending colon of the large intestine. It is separated from the ileum by the ileocecal valve (ICV), also called Bauhin's valve. It is also separated from the Large intestine#Structure, colon by the cecocolic junction. While the cecum is usually intraperitoneal, the ascending colon is Retroperitoneal space, retroperitoneal. In herbivores, the cecum stores food material where bacteria are able to break down the cellulose. In humans, the cecum is involved in absorption of Salt (chemistry), salts and Electrolyte, electrolytes and lubricates the solid waste that pas ...

Lagomorpha
The lagomorphs () are the members of the taxonomic order Lagomorpha, of which there are two living families: the Leporidae (rabbits and hares) and the Ochotonidae ( pikas). There are 110 recent species of lagomorph, of which 109 species in twelve genera are extant, including ten genera of rabbits (42 species); one genus of hare (33 species) and one genus of pika (34 species). The name of the order is derived from the Ancient Greek (, "hare") + (, "form"). Taxonomy and evolutionary history Other names used for this order, now considered synonymous, include: ''Duplicidentata'' (Illiger, 1811); ''Leporida'' (Averianov, 1999); ''Neolagomorpha'' (Averianov, 1999); ''Ochotonida'' (Averianov, 1999); and ''Palarodentia'' (Haeckel, 1895; Lilian, 2016). The evolutionary history of the lagomorphs is still not well understood. In the late 20th century, it was generally agreed that '' Eurymylus'', which lived in eastern Asia and dates back to the late Paleocene or early Eocene, was a ...

Altricial
Precocial species in birds and mammals are those in which the young are relatively mature and mobile from the moment of birth or hatching. They are normally nidifugous, meaning that they leave the nest shortly after birth or hatching. Altricial species are those in which the young are underdeveloped at the time of birth, but with the aid of their parents mature after birth. These categories form a continuum, without distinct gaps between them. In fish, this often refers to the presence or absence of a stomach: precocial larvae have one at the onset of first feeding whereas altricial fish do not. Depending on the species, the larvae may develop a functional stomach during metamorphosis (gastric) or remain stomachless (agastric). Precociality Precocial young have open eyes, hair or down, large brains, and are immediately mobile and somewhat able to flee from or defend themselves against predators. For example, with ground-nesting birds such as ducks or turkeys, the young are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
