It is an exciting but not uncommon site to see when a pack of javelinas stroll across the Tanque Verde Ranch. Javelinas are also commonly seen among horseback riding, mountain biking, and hiking activities at the ranch. They may look grungy with a hint of cuteness, but they can be quite foul. Javelinas are fun to watch, no doubt, but keeping a safe distance is extremely important as they can be harmful if they feel threatened.
Javelinas are NOT Rodents
Because of the similarity of appearance to the capybara, the world’s largest rodent, some people believe the javelina is a rodent. Here are some things you can look for to distinguish the differences between Javelina and Rodents:
- Rodents are a group of mammals characterized by two upper and two lower incisors that grow continuously during their lives. Javelinas use a constant gnawing of hard materials, such as wood, to wear down the teeth.
- Rodents have no canine teeth. Javelinas have four uppers and six lower incisors. They have two upper and two lower canines which are flat-sided. These canines rub against each other every time javelinas opens and closes their mouths, sharpening the teeth like a knife over steel. They are excellent digging tools.
Javelinas are NOT Pigs
There are also many misconceptions that Javelinas are part of the Suidae family (pigs, boars, warthogs, etc.) Because of the pig-like nose and the canines that resemble a pig’s tusks, many think javelinas are a pig. They are not related. All of the pigs in the United States, domesticated or wild, are descendants from animals brought from Europe or Asia. The javelina evolved in the Americas. Here are the differences you can look for:
- Most obvious is size. A pig at 150 pounds is a runt while javelina at 50 pounds is large.
- When a pig gives birth, she has a large litter of blind, helpless piglets that she feeds while laying down. Javelina typically has twins that are on their feet the day they’re born, running with the herd the next day while Momma feeds them standing up.
Javelinas ARE Herbivores
Mistakenly called a pig or a rodent, the javelina, pronounced ‘have-uh-LEEN-ah,’ is a member of a family of mammals known as the peccaries. Native to the Americas, they are rooting animals found in southern Texas and Arizona. They have an excellent sense of smell but have poor eyesight. They are not aggressive, but like all wild animals, they will defend themselves if they feel threatened by humans approach.
When you visit the ranch be sure to keep your eyes out for these exciting desert creatures so you can take pictures, and videos of them, or see them parade out in the distance while on horseback. Be sure to tell all your family and friends about javelinas now that you know so much about them. If you have any questions or further interests stop by the Nature Center at Tanque Verde Ranch to learn more and see related exhibits.
