Peccary

Peccaries are medium-sized animals that look very much like pigs.

They belong to a family called Tayassuidae. While they look like pigs, they are actually different. Peccaries have small, rounded ears and very short tails. Their most special feature is their teeth. They have short, straight tusks that lock together. This prevents their jaws from moving side-to-side. These tusks help them crush hard seeds and slice through plant roots. They also rub their tusks together to make a chattering noise. This sound warns predators to stay away from the group.

Peccaries are social creatures that live in groups called squadrons.

A typical squadron has about six to nine members. However, some white-lipped peccary groups can have over 100 individuals. These animals rely on their social structure to stay safe. They use the group to defend their territory and protect against predators. They also use each other to help regulate their body temperature. Because peccaries have very poor eyesight, they use smell to find one another. They have scent glands below their eyes and on their backs. They rub these glands on each other to recognize friends. This strong odor is why people sometimes call them "skunk pigs."

These animals have a very long history on Earth.

The oldest fossils of peccaries come from the Early Miocene in North America. A long time ago, during the Pliocene and Pleistocene, they moved into South America. This happened during the Great American Interchange when the Isthmus of Panama formed. This land bridge connected the two continents. At that time, many animals like llamas and tapirs also moved between lands. Some types of peccaries, like the Mylohyus, lived in North America until 12,000 years ago. They disappeared at the end of the Pleistocene period when humans arrived.

There are a few different types of peccaries living today.

The collared peccary lives from the southwestern United States down to South America. It has a dark coat with a light collar around its shoulders. They can live in many places, including cities and farms. The white-lipped peccary lives mostly in rainforests and grasslands. Another type is the Chacoan peccary, which lives in the Chaco region. Scientists once thought this species was extinct until they found it in Paraguay in 1975. There is also a possible fourth species called the giant peccary in the Amazon.

Peccaries are omnivores, which means they eat both plants and animals.

They love to eat roots, grasses, seeds, and fruit. They also enjoy eating cacti, especially the prickly pear. Sometimes they will eat insects, grubs, or even small animals. Their bodies are built to handle these different foods. They are foregut fermenters, which is a way of digesting food. This is similar to how some other animals process plants. You might see them in places like Arizona, where they are often called javelinas. They are an important part of the wild world in the Americas.
