Unlike most species on Serpnosis, the Simiteryx live on top of the trees instead of underneath in the pitch black jungles. They live in small huts and spend their days sunbathing to absorb sunlight. At night they delve into the jungles to hunt. They jump from tree to tree to navigate, avoiding the jungle floor. They are rivals with the Pytholeptics as the dominant species on the planet.
