Swine

Swines, also called pigs, were quadrupedal mammals. Their main physical characteristics, including their blunt-ended nose, large size, and hooves, were archetypal of porcine species. To compare a person to a pig was an insult, at least amongst Rutanians and Calian Humans. The expression "pearls before swine" referred to giving things of value to those who would not understand or appreciate it.

In addition, some sentient species such as the Ugnaughts and Gamorreans had physical similarities to pigs, namely the snout and, to a lesser extent, their vocal language. In the latter case, their similarities were to such an extent that Gamorrean guards have even been called pig guards due to the resemblance.

Rebel pilot Jek Porkins was playfully nicknamed "Piggy" by his squad mates, who often teased him about his heavyset physique. Years after Porkins' death at the Battle of Yavin, Wes Janson and Wedge Antillies told Wraith Squadron's Gamorrean recruit Voort saBinring, that they did not consider his nickname "Piggy" derogatory, but a legacy to live up to.
