The pigasis has a sense of smell that is very well developed. Its hearing is also acute, though its eyesight is comparatively weak, lacking color vision; however, all of this, allows one to distinguish between different creatures of roughly the same size. As a result, when engaging in combat, the pigasis can seem to be rather chaotic. However, as to combat, this boar-like creature possesses mutations that protect against venom. As such, snakes have become part of the species regular diet.
 
Furthering the details of their social behaviors, the swine  live in female-dominated sounders consisting of barren sows and mothers with young led by an old matriarch. Male boars leave their sounder at the age of 8–15 months, while females either remain with their mothers or establish new territories nearby. Subadult males may live in loosely knit groups, while adult and elderly males tend to be solitary outside the breeding season, which is usually between November to January.
 
As stated above, their eyesight is poor, while their other senses are keen. This leads them to occasionally attack other creatures for known explainable reason other than mistaken identity. Although the species is small, one can fight quite aggressively, having a fierce bite-tusk attack. Additionally, it may use its flight to escape bad positioning to making flying passes during subsequent attacks. As it flies by, however, the technique does make it susceptible to flee-attack reactions.
