Species that are found in only one area and are especially vulnerable to extinction are referred to as which type of species?

Species that are found in only one area and are especially vulnerable to extinction are referred to as "endemic species." These species are typically limited to a specific geographic region, making them particularly susceptible to habitat loss, climate change, and other environmental pressures. Their restricted distribution means that any significant change to their habitat can have devastating effects on their populations. Conservation efforts are crucial to protect these unique species.
