Feral hogs and javelina look alike, but they are different animals managed in very different ways.

Feral hogs
Feral hogs descend from domestic pigs and Eurasian wild boar. They are an invasive species that tears up crops, competes with deer and turkeys, and spreads disease.

Javelina
The javelina, or collared peccary, is a native animal of the desert Southwest. It belongs to a separate family from pigs and is managed as a game animal with seasons and tags.
Why it matters
Hog rules aim at control, while javelina rules aim at a healthy population. Know which animal you are hunting.
