The Aruli (Aquae sicarius, meaning "assassin of water"), initially recognized as Gremlins by the ODSTs of Benjamin Janson's squad, are an amphibious crustacean-like species. They are the newest species to be utilized by the Covenant against humanity. Although not officially part of the Covenant, they are in fact galactic mercanaries that are hired by various species, factions and organizations throughout the Milky Way. Because of their mercenary status and similar skill set, the Aruli had extensive partnership with the Kig-Yar. As of 2532, they were planned to become officially indoctrinated into the Covenant, however, interference caused by Benjamin Janson in Halo: Victor would halt this process. After this, the Aruli race was presumably purged by the humiliated Covenant.
