Form and jaws#

What distinguished the species mechanically was its jaws. A Ruki carried a set of jaws considerably stronger than its size class would have predicted, and the same jaws drove the species's two most consistently recorded behaviours: the casual nipping of straying MatoranMatoranThe most abundant species in the Matoran Universe, chosen by Mata Nui to inhabit and maintain his cosmic body. fingers and the persistent chewing through of Ga-MatoranGa-MatoranThe Water-element Matoran of Ga-Metru and Ga-Koro, exclusively female, who taught the schools of Metru Nui and crewed the boats and bridges of the Mata Nui coast. infrastructure.

The same jaws made the species a routine maintenance problem for Ga-KoroGa-KoroGa-Koro is a village on the island of Mata Nui, inhabited by the Ga-Matoran and associated with both Nokama and Gali.

The Ruki was simply small enough to slip past the perimeter, equipped to bite through what it found, and present in numbers high enough to make the damage continuous.

Enmity with the TarakavaTarakavaHuge lizard-like Rahi with powerful forelegs, hunted in pairs across Mata Nui and Metru Nui. and the schooling effect#

The schooling effect underwrote the Ruki side of the relationship. A single Ruki against a single TarakavaTarakavaHuge lizard-like Rahi with powerful forelegs, hunted in pairs across Mata Nui and Metru Nui. was a meal; a school of Ruki against the same TarakavaTarakavaHuge lizard-like Rahi with powerful forelegs, hunted in pairs across Mata Nui and Metru Nui. was a problem the lizard preferred to disengage from.
