第2个回答 2007-11-25
1 The Felidae Family
Acinonyx jubatus (Cheetah)
Range and Habitat
Cheetahs range in the savanna regions of sub-Saharan Africa, and east of the rainforests in central Africa. A small population of approximately 200 cheetahs also occur in the Caspian Sea area in the countries of Iran, Turkey and Turkmenistan. Their range used to extend farther east to the Middle East and India, but have been eliminated and are thought to be extinct in these countries. The largest cheetah population exists in Namibia, with an estimated 2,000-3,000 cheetahs. However, even here their future is not secure, because Namibian farmers loose 10% of their livestock to cheetahs.
Physical Appearance
The cheetah is the most canid of all felines. They are adapted for running very fast. Males are slightly larger than the females. Cheetahs are shaped very differently from other felines. They have long, thin legs; a very lithe body (the same tapering shape as a greyhound); a very small and rounded head; and a very long thin tail that the cheetah uses as a balance when it runs. The cheetah has a yellowish-tawny-golden color coat with white underbody and face, and solid black spots all over its body, and a thick black tear stripe that runs from the inside corner of its eyes to its mouth. Their canine teeth are proportionately small for a cat, in order to make room for their enlarged nasal passages. Cheetahs claws don't retract completely, and their feet are wider in relation to their body size. The soles of their feet are covered with rough scaly pads, in order to grip the ground while they run. All these characteristics help to make the cheetah the fastest land animal on the planet.
Unfortunately, though the cheetah's body was designed for speed, it was not designed for endurance, it is a sprint runner. Cheetahs can only keep up their fastest pace (70 mph) for 400 yards before their body overheats and their muscles begin to tire and produce lactic acid from exhaustion. In fact, the cheetah's body temperature can rise to over 105 degrees Fahrenheit, a fatal temperature. In order to help them get enough air to their huge lungs while they run, their nasal passage is very large and short. Their heart, lungs, bronchial tubes, and adrenal glands are larger, which also aid in the circulation of oxygen rich blood to the muscles.
The cheetah is poetry in motion when it runs. It has an extremely flexible spine, which it can flex and twist to increase its stride up to 20 feet in a single bound! Its hip, ankle, wrist and shoulder joints are also very flexible, as the cheetah sprints and dodges in numerous angles to catch its prey, and needs to be able to maneuver in a split second. The long thick tail acts as a rudder, and by flailing the tail around the cheetah can steer itself at very high speeds.
They are very easy to distinguish from the other large African spotted cat, the leopard, because they look so different. They have spots, whereas the leopard has rosettes. The cheetah is much smaller and thinner, and its legs are longer and very thin, where the leopard is much heavier and more muscular with proportionately shorter legs. The cheetah's head and muzzle is more rounded and smaller than the leopards, and the leopard can jump up in trees and stalk on the ground, whereas the cheetah is restricted to staying on the ground.
2 The Felidae Family
King Cheetah
For years, strangely marked skins from cheetahs have come out of Africa, as well as reports of a strangely-marked giant cheetah. In 1975, in Kruger Park, South Africa, cryptozoologists Paul and Lena Bottriell observed and photographed a king cheetah. It was larger than a normal cheetah, and had strange blotchy markings on its body. They were able to obtain mounted specimens of these creatures to study.
At first, people felt that this new animal was a hybrid cheetah-leopard cross. Some king cheetahs were captured, and genetic tests done on them determined that this was false. The unusual coat pattern was caused by a recessive allele (gene), which was known as the "tabby gene", because the same gene in domestic cats controls the tabby markings on them. King cheetahs are the same species, and can interbreed with normal cheetahs and produce fertile young of both types. King cheetahs can breed with each other and produce fertile young of both sexes. And king cheetahs can be born to a normal cheetah pair. The king cheetah is not a subspecies of cheetah, but unusually marked indivuduals within a population. The king cheetah turns up in clumps within populations, and are widespread throughout Africa.
In 1981, in the DeWildt cheetah center in South Africa, a "king" cheetah was born. It was the first king cheetah born in captivity. They have the same body structures as a normal cheetah, but the markings are bigger and all the spots are connected in a blotchy pattern. This new mutation is giving biologists hope, as they believe that such mutations may mean that the cheetah is beginning to regain some genetic diversity. Such mutations rarely exist in the wild, but they have been seen.
Diet and Hunting Behavior
Cheetahs prefer to eat small ungulates: the Thompson's gazelle, Grant's gazelle, impala; and even occasionally rabbits. The cheetah eats as much of the prey it caught as it can, and does not return to its kills because it cannot defend them. The cheetah trades speed for strength. It hunts during the day so as not to come into contact with more nocturnal predators as lions and hyenas, who kill their cubs and eat them, and will kill the mother if they can catch her. The cheetah is the most successful solitary hunter, succeeding in up to 70% of their hunts. This is due to the fact that the cheetah is specialized, and by no means reflects on the cheetahs ability to catch a wide variety of prey. The only other hunter that is more successful than the cheetah is the African wild dog, which is the most successful cooperative hunter, catching up to 80% of their hunts.
Cheetahs hunt by sight, sometimes standing atop termite mounds to survey their surroundings. Once the desired prey is sighted, the cheetah silently stalks it, until it is within 50 - 100 yards of it. Then it explodes into action, and chases its prey across the savannah. The cheetah's very flexible spine allows it the greatest running stride of all the big cats. It uses its long tail to balance it while it chases down its prey. And its extremely flexible hips allow it to make sharp turns. Once the prey is within reach, the cheetah uses its front paws to try and knock the legs out from under it. It then kills its prey by a choke hold from their small canines. During the hunt, they run so fast that their body temperature can reach up to 105 degrees farenheight, which can kill. So they can run very fast but don't have very good endurance. Unfortunately, after all this effort, the exhausted and overheated cheetah usually cannot eat, because larger predators can easily take it away from the tired cheetah, who even if she wasn't exhausted form the chase could not defend her food from them. Unlike most other carnivores, cheetahs never scavenge. They must eat fresh killed meat.
3 The Felidae Family
Reproduction and Life Cycle
Females reach sexual maturity at 2-3 years, and males at 3 years. Mating can take place year-round, but peaks during the rainy season (November to May). Like most cats, cheetahs are mating-induced ovulators, which means that they do not ovulate until after mating has occurred. In order for mating to take place, the female cheetah lays down and raises her rear end in the air, in a position called lordosis. The male cheetah's penis, like all carnivores, has a bone called the baculum, which serves to stimulate the female cheetah's vaginal wall. Also on the male cheetah's penis are tiny backwards facing spines, which are found only in the cat family. They are believed to provide stimulation for ovulation. The act of copulation itself lasts only a minute or two at most. They may mate several times a day, and the oestrus period, or receptive time of the female, lasts up to fourteen days.
After a gestation period of 90 - 98 days, she gives birth to 1-3 cubs in a burrow made in thick grass. The cubs weigh 250 - 300 g (8.8 - 10.6 oz) when they are born. They stay in the burrow for 8 weeks. During this time, the mother moves her cubs constantly to avoid detection by predators. Their first teeth come in at 3-6 weeks of age, and are replaced by adult teeth by 8 months old. Until the cubs are 3 months old, they are covered with a long, fuzzy grey coat, which gradually falls out and their sleek, spotted coats fill in. This unusual coloration is thought to be camouflage for the cubs. Cubs are weaned at 4 months old, but continue to stay with their mother until they are about a year and a half old. During this time they are taught how to hunt. Infant mortality rate is 71% before 2 months, and 95% from two months to 1 year old. The high infant mortality rate is due to starvation, disease, and predation by lions, baboons and hyenas. Those that do survive take 1 1/2 years to mature, and in that time they stick with their mother to learn how to hunt. She will not breed until her cubs either all leave her or die. Cheetahs can live for up to 15 years in the wild.
Social Behavior
Cheetahs are generally solitary and diurnal (active in the daytime) by nature, but they are actually more social than most felids, except the lion. They are most active during the daytime to aviod conflict with the more nocturnal lion and hyena, which are the cheetah's main enemies besides man. Females are usually found alone escept when she has young, and males live in coalitions of two to five members, trios being the most common. In areas of eastern and southern Africa, where other large predators have been eradicated, cheetahs are often seen in groups of 14 - 19 individuals. The males and females only get together to breed. After conception, the males leave the females and rejoin their coalitions. In these coalitions, the males live and hunt together, protecting one another from lions and hyenas, and providing food for everyone in the coalition, since it is easier to hunt in a group. Coalitions of cheetahs also have better success rates in establishing and maintaining a territory, and finding mates. Sometimes, a small family group consisting of males and females form. They hunt together as well, and are more successful than loners. The practice mutual grooming, which establishes bonds between members of the coalition. All cheetahs, whether they are the members of a coalition, or the lone cheetah, regularly mark off their home ranges with urine.
4 The Felidae Family
Cheetahs communicate with each other using a variety of sounds. Cheetahs don't meow, but they do chirp and squeak. Mother cheetahs chirp to call their young. They also purr to show contentment and growl to show aggression. Cheetahs also communicate using body language, like other cats. Flattened ears and bared teeth mean aggression, and this is accentuated by white spots on the backs of black ears.
Threats
All cheetahs are endangered due to excessive hunting for their skins, and severely inbred because of a plague that swept across Africa in the last Ice age over 10,000 years ago, leaving only a few thousand cheetahs. The animals also have a low recovery rate, and were unable to mutate to produce a more genetically stable population. Those that survived and dodged the bullets of hunters were responsible for perpetuation of the species. Because there was such a small gene pool left, all African cheetahs today are descended from these few hundred cheetahs, so most are related. This can be proven by comparing coat patterns. All marked animals (those with spots, rosettes, or stripes) have their own unique patterns. Several cheetahs have shown similar, if not near identical, coat patterns; even those that are several thousands of miles apart. Biologists have also noticed that skin grafts between unrelated cheetahs in zoos take, instead of being rejected as they normally would. Thus, the world of the cheetah looks very dim, as no new genetic material can be introduced. Cheetahs have a sperm count that is 90% lower than a tiger or lion, and on top of that, 75% of the sperm are abnormal, having multiple tails, no tail, multiple heads, and even no heads. Captive breeding programs have not been successful, as cheetahs will not readily breed in captivity, and unfortunately, the offspring produced usually die.
Cheetahs are also threatened by lions, who will kill adult cheetahs if they can catch them, and kill their cubs when they find them hidden in the grass. Lions and hyenas also steal the cheetah's kills, and since the cheetah is smaller, weaker, and cannot rick any physical damage, must relinquish its hard-earned kill.本回答被提问者采纳
