The capybara, greater capybara (Hydrochoerus hydrochaeris)
If you’re looking for an adorable and unexpected animal to admire, look no further than the capybara. This giant rodent, native to South America, has captured the hearts of animal lovers around the world with its gentle nature, peculiar habits, and surprising social skills. Despite being the world’s largest rodent, the capybara is often mistaken for a furry, oversized guinea pig. But don’t let its cute appearance fool you – these creatures are fascinating and complex species with a rich history and unique ecological role. So, let’s dive into the world of the capybara and discover what makes this unusual creature so captivating.
The capybara, or greater capybara (Hydrochoerus hydrochaeris), is an intriguing and unique mammal that is both adorable and fascinating to study. With a length of 106-134 cm (41.7-52.8 inches) and standing 50-62 cm (19.7-24.4 inches) tall at the withers, the capybara is the largest rodent in the world, but its appearance is often compared to a giant guinea pig.
Social animals
These creatures are social animals that live in groups of up to 20 individuals in the wild, with a dominant male leading the group. Capybaras are semi-aquatic and are excellent swimmers, using their webbed feet and streamlined bodies to navigate through waterways. They are also herbivores, primarily feeding on grasses and aquatic plants.
Capybaras have a unique digestive system that allows them to extract nutrients from tough, fibrous plant material, which is why they are known to chew on wood to wear down their constantly growing teeth. They are also known for their gentle and friendly demeanor, making them popular pets in some parts of the world.
Despite their cuddly appearance, capybaras play an important ecological role as keystone species in their native South American habitats, influencing the distribution and abundance of other species through their grazing and feeding habits. All in all, the capybara is an interesting and complex animal that continues to captivate the attention of scientists and animal lovers alike.
Taxonomy
The capybara (Hydrochoerus hydrochaeris) belongs to the family Caviidae, which includes other species of rodents such as guinea pigs and rock cavies. Within the family, the capybara is the only member of the genus Hydrochoerus.
The scientific name Hydrochoerus hydrochaeris is derived from Greek and means “water pig.” This is a reference to the capybara’s semi-aquatic lifestyle and its physical resemblance to a pig.
There are two recognized subspecies of capybara: Hydrochoerus hydrochaeris hydrochaeris, which is found in much of South America, and Hydrochoerus hydrochaeris isthmius, which is found in Panama and northern Colombia. The two subspecies are similar in appearance, but differ slightly in their physical characteristics and geographical ranges.
The capybara’s taxonomy reflects its unique position as the largest living rodent and a key member of the diverse and fascinating family of Caviidae.

Diet
Capybaras are herbivorous animals and primarily feed on grasses, aquatic plants, and fruits. Their diet can vary depending on their habitat and the availability of food sources. In grasslands and savannas, they feed on a variety of grasses, while in wetlands they feed on aquatic vegetation such as water hyacinths and duckweeds.
Capybaras have a unique digestive system that allows them to extract nutrients from tough, fibrous plant material. They are able to digest cellulose thanks to a specialized chamber in their stomach called the cecum. The cecum is home to bacteria and other microorganisms that help break down tough plant material and extract nutrients. Capybaras are also known to chew on wood to wear down their constantly growing teeth.
While they primarily feed on plant material, capybaras have been observed engaging in coprophagy, or the consumption of their own feces. This behavior is thought to help them extract more nutrients from their food and to help maintain the balance of microorganisms in their digestive system.
Capybaras are also known to travel long distances in search of food and water, and they are capable of covering up to 10 kilometers (6.2 mi) in a day.
Reproduction and parenting
- Capybaras are polygynous, meaning that a dominant male will mate with multiple females in the group.
