Through Herbivore, Rabbit and Dominance hierarchy

Members of the Lepus genus are considered true hares, distinguishing them from rabbits which make up the rest of the Leporidae family. There are five species with common names that include the word "hare" which are not considered true hares: the hispid hare, and four species known as red rock hares (belonging to the genus Pronolagus). Conversely, several Lepus species are called "jackrabbits", but classed as hares rather than rabbits. The pet known as the Belgian hare is a domesticated European rabbit which has been selectively bred to resemble a hare.

Biology

Hares are swift animals and can run up to 80 km/h (50 mph) over short distances. Over longer distances, the European hare (Lepus europaeus) can run up to 55 km/h (35 mph). The five species of jackrabbits found in central and western North America are able to run at 65 km/h (40 mph) over longer distances, and can leap up to 3 m (10 ft) at a time.

Normally a shy animal, the European brown hare changes its behavior in spring, when it can be seen in daytime chasing other hares. This appears to be competition between males (called bucks) to attain dominance for breeding. During this spring frenzy, animals of both sexes can be seen "boxing", one hare striking another with its paws. This behavior gives rise to the idiom "mad as a March hare". This is present not only in intermale competition, but also among females (called does) toward males to prevent copulation.

Hares, like all leporids, have jointed, or kinetic, skulls. This jointing allows for the skull to deform and better absorb the kinetic energy imparted by running. All hares have a dental formula of 2.0.3.31.0.2.3 × 2 = 28. This means that they have two pairs of upper and one pair of lower incisors, no canines, three upper and two lower premolars on each side, and three upper and lower molars on either side of the jaw.

Hares have a reputation for better backward vision than forward vision.

Differences from rabbits

Hares are generally larger and have exaggerated features compared to those of rabbits, particularly in their large ears, eyes, and hind feet. All hares have 48 chromosomes, while rabbits may have a number of chromosomes ranging from 38 to 52. Rabbits, particularly the European rabbit, have been domesticated; rabbit farmers produce meat, fur, and wool, in addition to breeding pets and laboratory animals. Conversely, no hares have been domesticated, though some captive populations are raised for food and to be released for sport hunting. (The Belgian hare is actually a breed of rabbit that has been bred to look more like a hare, most likely from stock of Flemish Giant rabbits.)

Some rabbits live and give birth underground in burrows, with many burrows in an area forming a warren. Other rabbits and hares live and give birth in simple forms (shallow depressions or flattened nests of grass) above the ground. Hares usually do not live in groups. Young hares are adapted to the lack of physical protection, relative to that afforded by a burrow, by being born fully furred and with eyes open. They are hence precocial, able to fend for themselves soon after birth. By contrast, rabbits are altricial, being born blind and hairless.

Diet

Easily digestible food is processed in the gastrointestinal tract, expelling the waste as regular feces. For nutrients that are harder to extract, hares, like all lagomorphs, ferment fiber in the cecum and expel the mass as cecotropes, which they ingest again, a practice called cecotrophy or refection. The cecotropes are absorbed in the small intestine to use the nutrients.

Habitat

Hares can be found in a wide variety of habitats, ranging from desert environments and arctic tundra to temperate grasslands, forests, swamps, mountains, and tropical regions. Some hares such as the snowshoe hare may change their fur color to better hide as the seasons change. The adaptability of the European hare to different environments has led to it becoming an invasive species in regions where it is newly introduced.
