Chaksky pekari [1] , or Chakoan pekari [2] ( lat. Catagonus wagneri ) - a mammal from the peccaria family. It was first discovered in 1930 from subfossil remains, but was not recognized as a surviving species until 1975 . Thus, Chak bakers are one of the most recently discovered large mammals. Today, about 3 thousand of their representatives have survived. Related to the extinct genus Platygonus .

Chak bakers have a strong face with a well-shaped nose. The coat color varies from brown to gray. A dark stripe runs along the back, white fur is on the shoulders. Chak bakers differ from other types of bakers in that they have longer ears, nose and tail. Around the mouth, unlike other bakers, there are white stripes. Another significant difference is that the Chak bakers have three toes on their hind legs, while the rest of the bakers have only two toes.
Habitats
Chak bakers earned the nickname "Green Hell Pigs" because of their wild, uncharted habitats. These animals prefer arid and wild habitats untouched by humans. To live in such conditions, they developed various devices, such as well-developed sinuses, which help them survive in dry, dusty conditions. The legs are rather short; this allows animals to maneuver among prickly plants.
Lifestyle
Chak bakers often migrate in herds of up to 10 animals. Such herds are active throughout the day, especially in the morning. In general, herds migrate for 42 days. This allows Chaksky bakers to control their territory.
Bakers are social animals, and therefore can communicate with each other using various sounds, usually grunts. Although sometimes Chak bakers can be aggressive, like biting each other, they are not as aggressive as other types of bakers.
When a predator threatens Chaksky bakers, all members of the herd line up in a defensive line. They are also able to secrete odorous substances that help them mark territory. Chak bakers often bathe in dust and dirt.
Nutrition
In the arid habitats of the Chak bakers, there is a rather sparse vegetation. They feed on various types of cacti . This contributes to the two-chamber stomach of these animals. Sometimes grazing bakers can eat acacia roots, pods and cactus flowers.
Reproduction
Young growth is usually born between September and December, but litters of Chak bakers were found year-round. Reproduction is associated with an abundance of nutrition, and, accordingly, with an abundance of rainfall. Before giving birth, the females leave the herd and then return to it again. Newborns can walk a few hours after birth. Chak bakers lack sexual dimorphism .
In total, the range of Chak bakers occupies 140,000 km². They are common in central South America from the west of Paraguay to southeast Bolivia and northern Argentina . This species is endemic in Paraguay, Bolivia and Southern Brazil .
