Animals move in multiple ways. They jump, run, swim or fly, making characteristic movements that serve them to move in the environment that is their own and also occasionally venture into other environments for which they are not adapted. This is how it is possible to observe fish that are able to fly or climb the trunks of trees, swimming and diving birds, and land mammals that have achieved a remarkable mastery of planned flight. In this article we will explain how animals move and move.
How birds fly
Insects and flying birds flap their wings to sustain themselves in the air and move their body forward. Both are equipped with ingenious mechanisms for flight: the first have seesaws that act as a kind of gyroscope to ensure direction, while in birds it is the semiricular canals of their inner ear that are responsible for the sense of balance and orientation. Flying fish move out of the water driven by their caudal fin and are held in the air by means of the unfolded pectoral fins, being able to glide and fly 300 meters.
How animals move in the water
The creatures that live in the sea, oceans, rivers move practicing a variety of movements. Among the best known is the wave movement of the vertical tail of fish (caudal fin), which acts as a true propeller. Ciliary movement is employed by many protozoa, who shake their filaments (cilia) as if they were oars. Jet propulsion, whose use in modern technology is widespread, recognizes its natural antecedent in the displacement of jellyfish and octopuses, which are propelled by violently throwing the water under their bodies. Other types of movements made to move by the inhabitants of the aquatic environment are known, such as the undulatory of eels, the rowing propulsion used by turtles and palmipeds and the characteristic of the hippocampus, produced by the undulation of its dorsal fin.
How reptiles move
Reptiles abduct, that is, they move by crawling on the ground. Not only do those who do not have legs abduct, such as snakes, but so do other reptiles. The lizard, like other saurians, advances by leaning on their short limbs and waving the muscles of the trunk. The earthworm advances by shrinking and lengthening the front of its body.
How mammals move
Most mammals have four legs and move on land, however, some use other ways to move. Aquatic mammals such as seals or whales and dolphins, swim with fins. Bats fly by their forelimbs, which are flippers. Monkeys use their hind legs and hands. Some may do it upright. Humans are bipedal and walk or run in their two lower extremities.
