They lived atop Knowledge Towers in Metru Nui, in small, tight-knit groups (for they learned that if too many nested at once, the towers would cave in). They had sharp claws, a long tail for balance, and excellent night vision. Preying on the Ice Bats that nested in Knowledge Towers, Crystal Climbers were extremely hard to remove once they were settled in a good hunting area. As a result of this habit, they were considered pests. Once the Great Cataclysm struck and most Vahki were eliminated, the Rahi settled in the Knowledge Towers permanently.
