A tepui is a flat-topped mountain found in the Guiana Highlands of South America, particularly in Venezuela, Guyana, and Brazil. These unique geological formations rise abruptly from the surrounding landscape, often featuring steep cliffs and diverse ecosystems. Tepuis are known for their rich biodiversity, including many endemic species of plants and animals that have evolved in isolation. The term "tepui" comes from the indigenous Pemon language, meaning "house of the gods." These mountains are often shrouded in clouds and mist, creating a mystical appearance. Tepuis are significant for scientific research, as they provide insights into evolution and ecology due to their distinct habitats.
