Ludos were tree-dwelling creatures found living near swamps and rivers on the forested planet Ganlihk. They had round bodies surrounded by several tentacles. Each tentacle had multiple suckers, and two "fingers" on the end. In water and mud, these agile appendages were used to sift through the silt to catch fish and other small prey. On land, they were used to climb trees and forage for fruit. Ludos typically spent the day basking in the treetops, coming down in the early morning to fish or eat the leftovers discarded by larger predators.
