Their name, "javelina," comes from the Spanish for javelin and refers to their javelin-like upper canines.
It is also known as the collared peccary, the musk hog, or tayaussa.
Javelinas are not closely related to wild or domesticated hogs even though they have a close physical resemblance to them.
They usually retreat from humans and attack only when cornered.
They have two hooves on each foot; 4 toes on each fore foot and 3 toes on each hind foot.
Javelinas have straight downward pointing tusks as opposed to pigs which have curved tusks.
They are highly intolerant of extreme temperatures and are very difficult to spot in very hot or cold periods.
Young travel with the herd one day after birth.
