This page features lists of species and organisms that have become extinct. The reasons for extinction range from natural occurrences, such as shifts in the Earth's ecosystem or natural disasters, to human influences on nature by the overuse of natural resources, hunting and destruction of natural habitats.
Habitat size and numbers of species are systematically related. Physically larger species and those living at lower latitudes or in forests or oceans are more sensitive to reduction in habitat area. [23] Conversion to "trivial" standardized ecosystems (e.g., monoculture following deforestation) effectively destroys habitat for the more diverse ...
Last collected in 1938. Extinct due to predation by, and competition with the mosquitofish and other introduced species. [89] Durango shiner: Notropis aulidion: Tunal River, Durango, Mexico Last collected in 1961. Possibly extinct due to pollution, competition and predation by the largemouth bass and other introduced species. [89] Salado shiner
As of 2022, the International Union for Conservation of Nature (IUCN) listed 40 animal species as extinct in the wild. [1] That is approximately 0.04% of all evaluated animal species. The IUCN also lists five animal subspecies as extinct in the wild. This is a complete list of wild animal species and subspecies listed as extinct by the IUCN.
Extinction of a species may come suddenly when an otherwise healthy species is wiped out completely, as when toxic pollution renders its entire habitat unliveable; or may occur gradually over thousands or millions of years, such as when a species gradually loses out in competition for food to better adapted competitors.
The main drivers of marine species extinction are habitat loss, pollution, invasive species, and overexploitation. [105] [106] Greater pressure is placed on marine ecosystems near coastal areas because of the human settlements in those areas. [107] Overexploitation has resulted in the extinction of over 25 marine species.
The species include a fruit bat, two species of fish, eight types of mussels and 10 types of birds.
Mass extinctions are characterized by the loss of at least 75% of species within a geologically short period of time (i.e., less than 2 million years). [18] [51] The Holocene extinction is also known as the "sixth extinction", as it is possibly the sixth mass extinction event, after the Ordovician–Silurian extinction events, the Late Devonian extinction, the Permian–Triassic extinction ...
