What does the term "endemic species" mean?

The term "endemic species" refers to species that are native to and found exclusively within a specific geographical area. This characteristic means that these species have evolved in a particular location and are adapted to the local environment, resulting in a unique biological identity. Endemic species often have narrow habitat requirements and can be particularly vulnerable to changes in their environment, making them an important focus of conservation efforts.

For instance, many islands have unique endemic species that are not found anywhere else in the world due to their isolation. This concept highlights biodiversity and the unique ecological characteristics of different regions. The specificity of their geographical distribution is a key factor in understanding how ecosystems function and change.
