What is endemic species?(答案OVER 1 个）
An endemic species is a species that lives in clusters within a restricted habitat in a specific location
Endemism is a term used in biology to talk about the distribution of a taxon limited to a small geographic area and which can therefore be found naturally in this place. In consequence, endemic species are those that live in a limited area, such as a mountain range, lake or island, among others.
Endemic species are those known to occur naturallywithin one country only. Threatened species are thosewhose extinction risk is classified as 'CriticallyEndangered', 'Endangered', or 'Vulnerable'. They are at ahigh or greater risk of extinction in the wild.
Endemic species are those found in only one region of the world. Their habitat is limited and restricted, and there are no other populations of the same species beyond those limits anywhere else in the world. For example, the kangaroo is endemic to Australia as it can only be found naturally there.
