Rabbits (scientific name is Leporidae) are small fluffy mammals belong to the family Leporidae, of the order Lagomorpha. Over the world, rabbits can be identified in eight different genera in the family. Some of rabbit species are: European rabbit (Oryctolagus cuniculus), cottontail rabbits (Sylvilagus) and the Amami rabbit ( Pentalagus furnesssi, which is considered a harmful species in Japan). Besides, some species can be considered to closely relate to rabbit are pikas and hares (which are in the order Lagomorpha).
Generally, rabbits may have many different colors and color patterns in their entire bodies. In their ventral surface of their bodies (the belly part), colors are often lighter than the dorsal surface (the back side). The most frequent colors of rabbit’s body are white, gray and brown. According to “Rabbits – The Animal Answer Guide” [RTAAG] by Susan Lumpkin, the color pattern of rabbit is called “agouti”, a hue that actually emerges from subtle mixtures of color on individual hairs. An agouti hair is black at the base, yellow in the middle, and black again at the tip. These characters leave the overall impression of brown to reddish to gray color, depending on the relative amount of two pigments: pheomelanin, which produces red and yellow colors, and eumelanin, which produces dark colors (RTAAG, p49) . Looking from a far distance, rabbit seems to have a full and egg-shaped body. The size of rabbit are ranged from 20 cm (8 inches) in length and 0.4 kg in weight to 50 cm (20 inches) and more than 2 kg. Especially, the long ears, which are the longest part of its body, can be more than 10 cm (4 inches) (The Rabbit Book [TRB], Samantha Johnson, p.90). These long ears often point up or come downwards. On the head of rabbit, there are two large eyes, which can be either brown or less frequently blue or grey. Under these eyes, it is teeth – the famous part of rabbit. Its teeth are often long and white, especially the two center teeth are the most longest and biggest. Many rabbits have what is called a “dewlap” blow theirs chin and down over their chests. It makes rabbit seem to have double chins (which actually help them store fat and energy). In fact, rabbit is often known as a fast and active animal. This consideration comes from its special legs. Normally, rabbit often has 4 legs with 5 claws on each front foot and 4 longer claws on its large flat back feet. These legs are often large and powerful. The two front paws may have 5 toes, with the extra can be called dewclaw and the hind feet have 4 toes. Rabbit’s fur is often long and soft. The tail is quite small and it is a little plume of brownish fur.
Land is the most favorable environment for rabbit to live. Some of their most popular living areas are meadows, woods, forest, grasslands, deserts and wetlands, where rabbit can easily find abundant source of grass – their favorite nutrient (Rabbit Biology[RB], 2012). Of the best known and wide ranged species, the European rabbits are often found in underground burrows (rabbit holes). The population of rabbit is not balanced over different countries in the world. While more than one half of rabbit’s population locates in North America, Europe, Africa and South America, the rest of them cannot stay in most part of Eurasia (where has many species of hares living there). In South America, where rabbits just immigrated recently, many areas have only one kind of rabbit, and some even do not have any kinds of this animal. (Wikipedia)
The main breeding season of rabbit is primarily in rainfall season and the early growth of high protein plants period. Besides, they can still breed at any other time when they are able to get sufficient protein from vegetation (Rabbit Biology). During the breeding season, rabbits often engage in extended chase, wild leaps, circling and boxing. According to RTAAG (p.111), boxing is a typical behavior of a pursued female rabbit, when...
