Predator and Prey
We explain to you what are predators and prey, what are the differences between predator and predator and examples of predatory animals.
What are predators and prey?
Predation is a key system in the life cycle . It is a mechanism of transmission of carbon and energy, from the simplest forms of life to the most complex, also exerting a pressure on the known species as a natural selection, which is no more than the competition to survive and reproduce, and is one of the most effective engines for evolution.
Said system is then composed of predator and prey. The biological interaction between one and the other is that the predator or predator hunts the prey and feeds on the organic matter of its body, thus obtaining energy and the matter necessary to survive.
Of course, predators can also be prey to other larger predators, so that the species feed on each other forming what is known as the food chain or food chain (represented by often as a pyramid), whose balance and continuity keeps the populations of a given ecosystem balanced. Thus, the predatory-predatory relationship is essential for ecological harmony and occurs naturally, spontaneously, provided there are no human interference.

Differences between predator and predator
The terms predator and predator are synonymous, that is, there is no difference in use or meaning between one and the other . Both come from the Latin depraedator, derived from the verb praedari ( robar, arrebatar, acquire a bot n ), which in turn comes from praeda, ( presa ). Its application to the animal kingdom occurred historically as a loan or metaphor.
Examples of predatory animals
Some simple examples of predatory animals are:
- The big jungle and savannah felines. Lions, panthers, tigers, pumas, etc.
- The large amphibious, aquatic or terrestrial reptiles. Among them the crocodiles and alligators, which surprise their prey when they go to drink water, but also the Galapagos lizards, the Komodo dragons and, on a much smaller scale, the toads and the iguanas, predators of numerous species of insects.
- Many arachnids Especially spiders, which capture prey with their nets; or the scorpions, which inject them with their stinger a paralyzing poison.
- Snakes and boas. Some of which employ the poisonous bite, and others the asphyxiating constriction, to capture their prey.
- The birds of prey. Predators of rodents, lizards and other small animals, such as eagles, hawks, owls, etc.
- The praying mantis. Fierce and voracious insects that can feed on insects, fish, small rodents or other mantises.
- The wild bears. Especially brown bears, grizzly bears or polar bears, active hunters in their respective ecosystems.
- The Sharks. The largest and fiercest sea predators, along with other fish such as barracudas, killer whales, etc.
