World Fastest Animal
World Fastest Land Animal
The cheetah is the world's fastest land mammal. With acceleration that would leave most automobiles in the dust, a cheetah can go from 0 to 60 miles (96 kilometers) an hour in only three seconds. These big cats are quite nimble at high speed and can make quick and sudden turns in pursuit of prey.
Before unleashing their speed, cheetahs use exceptionally keen eyesight to scan their grassland environment for signs of prey—especially antelope and hares. This big cat is a daylight hunter that benefits from stealthy movement and a distinctive spotted coat that allows it to blend easily into high, dry grasses.
When the moment is right a cheetah will sprint after its quarry and attempt to knock it down. Such chases cost the hunter a tremendous amount of energy and are usually over in less than a minute. If successful, the cheetah will often drag its kill to a shady hiding place to protect it from opportunistic animals that sometimes steal a kill before the cheetah can eat. Cheetahs need only drink once every three to four days.
Female cheetahs typically have a litter of three cubs and live with them for one and a half to two years. Young cubs spend their first year learning from their mother and practicing hunting techniques with playful games. Male cheetahs live alone or in small groups, often with their littermates.
Most wild cheetahs are found in eastern and southwestern Africa. Perhaps only 12,000 of these big cats remain, and those are under pressure as the wide-open grasslands they favor are disappearing at the hands of human settlers.
World Fastest Ocean Animal
Sailfish are two species of fishes in the genus Istiophorus, living in warmer sections of all the oceans of the world. They are blue to grey in color and have a characteristic erectile dorsal fin known as a sail, which often stretches the entire length of the back. Another notable characteristic is the elongated bill, resembling that of the swordfish and other marlins.
Both species of sailfishes grow quickly, reaching 1.2-1.5 m (4-5 ft) in length in a single year, and feed on the surface or at mid-depths on smaller pelagic forage fish and squid. Individuals have been clocked at speeds of up to 110 km/h (70 mph), which is the highest speed reliably reported in a fish. Generally, sailfish do not grow to more than 3 m (10 ft) in length and rarely weigh over 90 kg (200 lb), although larger specimens have been seen off the shores of Costa Rica.
The sail is normally kept folded down and to the side when swimming, but it may be raised when the sailfish feels threatened or excited, making the fish appear much larger than it actually is. This tactic has also been observed during feeding, when a group of sailfish use their sails to "herd" a school of fish or squid.
Sailfish are highly prized game fish and are known for their incredible jumps. The sailfish also turns its body light blue with stripes when excited, confusing some fish and making it easier to catch prey.
World Fastest Flying Animal
The Peregrine Falcon (Falco peregrinus), also known simply as the Peregrine, and historically as the "Duck Hawk" in North America, is a cosmopolitan bird of prey in the family Falconidae. It is a large, crow-sized falcon, with a blue-gray back, barred white underparts, and a black head and "moustache". It can reach speeds over 322 km/h (200 mph) in a dive, making it the fastest animal in the world. As is common with bird-eating raptors, the female is much bigger than the male. Experts recognize 17–19 subspecies, which vary in appearance and range; there is disagreement over whether the distinctive Barbary Falcon is a subspecies or a distinct species.
The Peregrine's breeding range includes land regions from the Arctic tundra to the Tropics. It can be found nearly everywhere on Earth, except extreme polar regions, very high mountains, and most tropical rainforests; the only major ice-free landmass from which it is entirely absent is New Zealand. This makes it the world's most widespread bird of prey. Both the English and scientific names of this species mean "wandering falcon", referring to the migratory habits of many northern populations.
While its diet consists almost exclusively of medium-sized birds, the Peregrine will occasionally hunt small mammals, small reptiles or even insects. It reaches sexual maturity at one year, and mates for life. It nests in a scrape, normally on cliff edges or, in recent times, on tall human-made structures. The Peregrine Falcon became an endangered species in many areas due to the use of pesticides, especially DDT. Since the ban on DDT from the beginning of the 1970s onwards, the populations recovered, supported by large scale protection of nesting places and releases to the wild.
