The babirusa, a primitive pig, has tusks that grow through its snout on its upper jaw and grow straight upward. These tusks then curve back toward the animal's face and eyes. If not broken off occasionally, a tusk could grow in almost a complete circle. This could end up pushing against the babirusa's head and into its skull, ultimately killing it.

Pigs are exceedingly loud creatures.
A University of Illinois study measured average pig squeals that ranged from 100 to 115 decibels. The supersonic Concorde jet, by comparison, was originally banned from New York when its engines exceeded 112 decibels at takeoff. The wild boars had smashed through the glass doors while the Brandenburg shop was shut. A children's pig-kissing contest in Colorado is being forced to find a new name because another organisation claims it owns the Kiss a Pig concept. YouthZone, a children's organisation, has run the annual fundraiser in Roaring Fork Valley for ten years.
