Rhino Resource Center

Welcome to the world's largest online rhinoceros library dedicated to assisting research and conservation efforts globally.

Rhinos have complex social lives

Far from being solitary brutes, rhinos display surprising social intelligence. They communicate through an elaborate system of scent marks, vocalisations, and shared middens (dung piles) that serve as community message boards.
