What is a "hump"?

A hump is a distinctive anatomical feature commonly associated with certain large mammals, such as camels and bison. It is a rounded, protruding area located on the back or shoulders of the animal. The hump is primarily composed of fat tissue, which serves as an energy reserve for the animal during times of scarcity, allowing it to survive in arid or harsh environments. In camels, the hump stores fat that can be metabolized for sustenance and water when food and water sources are limited. The hump is an evolutionary adaptation that enables these animals to thrive in challenging habitats and withstand the demands of their unique ecological niche.
