Auyan-tepui’s summit has its own endemic species community, sharing some species with Roraima and other nearby tepuis but also hosting organisms found only on its own plateau.

The Chimantá Massif is a complex of interconnected tepui summits covering more than 700 square kilometers — one of the largest plateau complexes in the tepui highlands.

Its complex topography includes multiple summit levels, separated by lower-lying areas that provide different ecological conditions than the highest surfaces.

The Chimantá system has been the site of some of the most intensive botanical and biological research in the tepui region, including the discovery of numerous species new to science.

Cerro de la Neblina, on the Venezuelan-Brazilian border in the far south, is Venezuela’s highest peak at approximately 3,014 meters — higher than Roraima.
