Gerutas are flying, extremophile predators that are native to the volcanic caves in the Norfair region on Zebes. They are avid hunters, akin to the Reo, possessing a heat-resistant carapace and large claws. The Geruta has a unique means of flight, as it uses two jets that allow it to dive onto its prey like a rocket. It is unknown how the Geruta uses such jets, but it can be guessed that it is because it evolved in a volcanic environment.
While the species went extinct in the wild upon the destruction of their homeplanet of Zebes, a number were known to have been taken off-world at some point to the Biologic Space Laboratories research station above SR388, these samples were eventually infected by X Parasites and transformed into Gerubosses and most likely Gerudas. Ultimately the BSL station was destroyed as well, leaving the Geruta at extinct status unless other specimens reveal themselves.
