Clarify that the list refers to animals that excel in speed over others in their respective "type of movement" as there are many marine animals, flying and quadrupeds reaching speeds greater than some here.
6th Possibly the insect fastest land of nature is the tiger beetle ( Carabidae Cicindelinae ) because it has been considered one of the fastest animals in the world, but only can reach 10 km / h, if we compare its size with that of a human being, is to run at almost 400 km / h.
5 The black mamba ( Dendroaspis polylepis ) is a species of snake of the family Elapidae , is the most venomous snake in Africa and one of the most dangerous in the world due to its speed. With an average length of 2.5 m, can reach 4.5 m. Its name comes from the color black in your mouth can vary the color of his skin yellowish green to a metallic gray. It is one of the fastest snakes in the world, capable of moving from 16-22 km / h on land even with a third of its body off the ground and may even triple your speed in the water.
4 The fastest fish is more mako shark. The mako shark is a very active, of enormous strength and great speed due to its aggressiveness is able to attack large fish. According to recent evidence the mako can reach top speeds of over 124km / h post gives the fastest animal in the ocean, as previously belonged to sailfish with its 110 km / h. The secret of such power and speed is your perfect hydrodynamics, powerful muscle mass, its tail fin crescent shaped and being warm blooded , which triples allowing muscle power also make sudden starts. This combination of strength and speed gives these animals the ability to jump high out of the water, as does the white shark , these jumps usually make them when you are caught on a fishing hook, during which can reach between 6 and 8 feet high.
3 The ostrich the more swift bipedal animal. Compared to an athlete runs 90 km per hour, nearly double a person. Besides the bird is now bigger and heavier, can reach 3 feet tall, and weigh about 180 kg. It has a small head relative to the body, large eyes that measure two inches in diameter and provide an excellent view, flat peak, blunt, long neck bare of feathers like long legs, which are powerful and muscular, perfectly adapted to run, reaching over 90 km / h sustained for 30 minutes.
2 The cheetah is the fastest four-legged animal, reaching a top speed between 95 and 115 km / h in sprints up to 400-500 meters. They can go from 0-103 km per hour in just 4 seconds. It is a "racing machine" very effective and specialized in catching their prey in short chases.
1 Peregrine Falcon ( Falco peregrinus ) ranks first in the list because it is the fastest animal on the planet. It can fly at a cruising speed of 100 km / h, but when hunting making a diving attack, can reach more than 300 Km / h.
The Peregrine Falcon became an endangered species in many areas due to the use of pesticides, especially DDT.
Recently I showed one versus a Peregrine Falcon against a Dove can enjoy here .
