Capable of advanced forms of communication, members of this species are known to employ complex tactics when hunting. Undoubtedly the top land-based predators in Northern Corum—aside from humans—few creatures are able to withstand an attack by two or three Siu-Illt-Nas. Standing at around a meter tall, this bipedal creature uses its razor-sharp talons to disembowel prey, before biting into flesh with its razor-sharp teeth. Females of this species tend to be more red in color than males, which tend to feature three to four small backwards facing horns.
Found in only 6 out of 20 Pallisican cities in Corum, this species is common.
As pack hunters, Siu-Illt-Nas are known to employ the use of complex vocalizations in order to communicate with other members of their group, especially when hunting larger prey such as the Giid-Lisea-Eda or the Eeli-Illt-Eda. Researchers working for the New Zimian Space Exploration and Settlement Agency have documented at least a dozen of the Siu-Illt-Nas' distinct vocalizations. In the clip below, one hears a group of three Siu-Illt-Nas become excited at the sound of a nearby Giid-Lisea-Eda. Among the vocalizations heard in this clip, one hears the high pitched squeals of two subordinate members of a hunting party, and the loud, drawn out croaking sound of a hunting party leader.
The range of the Siu-Illt-Nas extends across 11.15% of the landmass of Corum. The majority of the species' range - 64.83% - lies within the continent's Mediterranean climate regions, while almost 16% lies in the Temperate climate regions of Isani Sweep. That said, southern Corum is home to a number of remote populations of feathered Siu-Illt-Nas, which are far more aggressive than their generally featherless, northern counterparts.
The Siu-Illt-Nas is regarded as a highland creature, although its territory extends across the lowlands of Northern Corum. Populations of Siu-Illt-Nas have been documented in the Central Riponian Mountains.
