Capybaras, the world’s largest rodents, are social, semi-aquatic mammals native to South America. Known for their webbed feet, diverse vocalizations, and friendly behavior, they thrive in water-rich habitats. Learn intriguing insights into their biology, habits, and role in the ecosystem.
Capybaras
Capybaras are the world’s largest rodents, growing up to 4.4 feet (1.34 meters) long and weighing between 77 and 146 pounds (35-66 kg).
They have barrel-shaped bodies, short legs, and slightly webbed feet, making them excellent swimmers.
Their eyes, ears, and nostrils are located high on their heads so they can stay mostly submerged while keeping watch for predators.
Capybaras are herbivores, primarily grazing on grasses, aquatic plants, fruits, and tree bark.
To maximize nutrition, they practice autocoprophagy—eating their own feces to regain beneficial gut bacteria.
Their teeth grow continuously to compensate for constant wear from chewing tough vegetation.
Capybaras live in highly social groups, often numbering 10 to 40 individuals, including one dominant male, females, and juveniles.
They communicate with a wide range of sounds like purring, barking, whistling, and teeth chattering to convey social interactions and warnings.
These semi-aquatic mammals can stay underwater for up to 5 minutes and often sleep while floating in the water.
Despite their large size, capybaras can run on land up to 35 km/h (about 22 mph).
Their natural habitats are savannas, wetlands, rivers, and dense forests across South America.
Capybaras are prey to jaguars, anacondas, caimans, and birds of prey, so they are always alert.
Baby capybaras are able to eat grass almost immediately after birth and can swim within days.
They are known as “nature’s ottomans” because many smaller animals like birds and monkeys perch on their backs peacefully.
Capybaras have a friendly, calm demeanor, making them popular in wildlife parks and even internet culture as the “world’s chillest animals.”
