What type of species is referred to when it is mentioned as found only in a specific location?

Endemic species are those that are found exclusively in a particular geographical area and are not naturally located anywhere else in the world. This can occur because of various factors such as isolation by barriers (like mountains or oceans), specific habitat requirements, or unique evolutionary histories that lead to species adapting to local conditions. The idea of endemism highlights the unique biodiversity of specific locations, often emphasizing the importance of conservation efforts to protect such species and their habitats.

In contrast, invasive species are those that thrive outside their native range, often to the detriment of local ecosystems. Threatened species refer to those that face the risk of extinction, while native species are those naturally occurring in a specific area but may not be restricted to that location. Thus, the focus on the unique presence of endemic species distinguishes them in ecological studies and biogeography.
