While Australia is a continent and not an island, due to its geographical isolation, its unique fauna has suffered an extreme decline in mammal species, 10% of its 273 terrestrial mammals, since European settlement (a loss of one to two species per decade); in contrast, only one species in North America has become extinct since European settlement.
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.
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.
The list of extinct mammals could go on for ages, but each animal has a unique story. With today’s advanced research, we can learn so much from animals that haven’t even existed during our ...
The shy Australian animals died after only a century of European settlement. Despite the world's last captive thylacine dying in 1936, the secretive animal wasn't declared extinct until 1986.
The species recovery score is a 0%–100% scale, with 0% being the species is extinct or extinct in the wild and 100% being fully recovered. [40] In addition, the Green Status also classifies previous and future conservation impacts with the Green Scores of Conservation Dependency, Conservation Gain, Conservation Legacy, and Recovery Potential.
In the natural course of events, species become extinct for a number of reasons, including but not limited to: extinction of a necessary host, prey or pollinator, interspecific competition, inability to deal with evolving diseases and changing environmental conditions (particularly sudden changes) which can act to introduce novel predators, or ...
The species Gigantopithecus blacki, which once lived in southern China, represents the largest great ape known to scientists — standing 10 feet tall (3 meters) and weighing up to 650 pounds (295 ...
