We explain what are predator and prey, what are the differences between predator and predator and examples of predatory animals.

The predator hunts the prey to feed on it and thus obtain energy.

What are predator and prey?

The predation is a key system in the life cycle. It is a mechanism for the transmission of carbon and Energy, from the simplest to the most complex forms of life, also exerting pressure on the species known as natural selection, which is nothing more than competition to survive and reproduce, and is one of the most efficient engines for evolution.

This system is then composed of predator and prey. The biological interaction between one and the other consists in that the predator hunts the prey and feeds on the organic material of your body, thus obtaining the Energy and the matter necessary to survive.

Of course, predators can also be prey for other larger predators, so that the species feed on each other forming what is known as the food chain or food chain (often represented as a pyramid), whose balance and continuity keep the populations of a ecosystem determined. Thus, the prey-predator relationship is fundamental for ecological harmony and occurs naturally, spontaneously, as long as there are no interference from the human being.

Differences between predator and predator

The terms predator and predator are synonyms, 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 ("steal", "snatch", "acquire a loot"), which in turn comes from praeda, ("prey"). Its application to animal Kingdom was historically given as a loan or metaphor.

Examples of predatory animals

Praying mantises feed on insects, minnows, small rodents, or other mantises.

Some simple examples of predatory animals are:

  • The big cats of the jungle and bed sheet. Lions, panthers, tigers, pumas, etc.
  • The big ones reptiles amphibians, aquatic or terrestrial. Among them crocodiles and alligators, who surprise their prey when they go to drink Water, but also Galapagos lizards, Komodo dragons and, on a much smaller scale, toads and iguanas, predators of numerous species of insects.
  • Many arachnids. Especially spiders, who capture prey with their webs; or scorpions, who inject them with a paralyzing poison with their sting.
  • Snakes and boas. Some of which employ the poisonous bite, and others the suffocating constriction, to capture their prey.
  • Birds of Prey. Predators of rodents, lizards and other small animals, such as eagles, hawks, owls, etc.
  • Praying mantises. Ferocious and voracious insects that can feed on insects, minnows, small rodents or other mantises.
  • Wild bears. Especially brown bears, grizzly bears or polar bears, active hunters in their respective ecosystems.
  • The Sharks. The largest and fiercest predators of the sea, along with other fish such as barracudas, killer whales, etc.
