Kleptoparasitism can also occur between individuals of the same species. This is the case of some raptors, whose name literally means “thief.” See in this video a case of kleptoparasitism on an owl: K leptoparasitism is stealing food that other species has caught, harvested or prepared. When a parasite causes illness or death of the host, it is called pathogen.Ĭymothoa exigua is a parasite that replaces the tongue of fish with their own body. Parasitism is considered a special type of predation, where predator is smaller than prey, although in most cases does not cause the death of the host. Parasites that live inside the host’s body are called endoparasites (such as tapeworms), and those who live outside ectoparasites (lice). Read this post to learn more! Reed warbler (Acrocephalus scirpaceus) feeding a cuckoo’s chick (Cuculus canorus). Fleas, ticks, pathogenic bacteria … are the best known, but there are also vertebrate parasites, like the cuckoo that lay their eggs in the nests of other birds, which will raise their chicks ( brood parasitism). Especially interesting are the “zombie parasites”, which modify the behavior of the host. Parasitism: one species ( parasite) lives at the expense of other ( host) and causes it injury.Great white shark (Carcharodon carcharias) jumping to depretade a marine mamal, maybe a sea lion.

This relationship is very important in evolution, as it allows natural selection acts by promoting the survival and reproduction of the most successful species according to their physiology, behavior … Rainforests are a clear example of competition between vegetals in the search for light.
