The African Buffalo is one of the largest and most powerful herbivorous mammals on the African continent, easily recognizable by its massive body, impressive horns, and dark coat. It primarily inhabits the savannas, grasslands, and open forests of sub-Saharan Africa. This social animal moves in large herds, sometimes composed of hundreds of individuals, which offer protection from predators through the collective strength of the group. The African Buffalo is a strict herbivore, feeding mainly on grasses and woody vegetation. Although it has a rather calm temperament, it can become extremely aggressive when threatened, and its physical strength makes it a formidable opponent for predators. Despite being a secondary predator, it is vulnerable due to hunting and habitat loss, although conservation efforts have helped stabilize some populations.

The Capybara is the largest rodent in the world, easily recognizable by its massive body and short, light brown fur. This semi-aquatic mammal primarily inhabits wetland areas of South America, near rivers, lakes, and swamps. The Capybara is an excellent swimmer and spends much of its time in the water, where it feeds mainly on aquatic grasses, plants, and fallen fruits. Naturally social, the Capybara lives in large groups of 10 to 20 individuals, often organized around a social hierarchy. The groups spend a lot of time grooming each other and protecting each other from predators. Although it is a calm and docile animal, the Capybara is threatened by the loss of its natural habitat due to urbanization and pollution of rivers. However, its population remains relatively stable, and it is often seen in protected areas.

The Caracal is an elegant feline, easily recognizable by its pointed ears adorned with tufts of black fur. It has a short tawny coat that allows it to blend into the dry, rocky environments where it lives, primarily in savannas, steppes, and semi-desert areas in Africa and Western Asia.
