A species of animal, plant, or other living organism that is in serious danger of extinction throughout all or a significant portion of its range. When a species is categorized as endangered, its numbers are so small that the species is at risk of extinction. To conserve an endangered species, whether animal (Fig. 1), plant, or another living organism, an adequate number of populations must be maintained within a sufficient amount of protected habitat, with the goal of minimizing the likelihood of future extinction. "Threatened species" is a related term, referring to a species likely to become endangered, at least locally, within the foreseeable future. See also: Conservation (species); Extinction
