Besides red squirrels, there are many other species of rodents that are equally smart and socially complex, living in societies, communities and in harmony with other animals. Most rodents develop deep, emotional relationships with their families or other members of their communities, and if living in captivity, as pets or for other reasons, they can even become deeply attached to their keepers or other animals.
One of the many remarkable facts about rodents, besides their intelligence and social complexity, is that their razor sharp incisors are in a state of constant growth and they can basically eat through pretty much anything. They have a constant need for gnawing at solid materials and they rather enjoy this activity. Another activity that they also highly enjoy is, of course, eating and chewing on seeds, wood and leafy veggies.
The capybara, for example, is the largest rodent in the world and can be as big as sheep, weighing up to 50 or 60 kg. These furry rodents are usually reddish brown and they mostly live on land, although always near bodies of fresh water. They have really big paws which makes them excellent swimmers. Some people say they can remain under water for up to 15 minutes, although this may just be a myth. The truth is that they are really fast swimmers and one can easily lose sight of them once they are submerged.
Capybaras live in the flooded grasslands between the territories of Panama and Paraguay, mainly in the Orinoco flow, Amazon, Paraguay and Paraná. There are also large populations of Capybaras living in the swampy areas, western Brazil and the flood plains of Venezuela and Colombia. Capybaras love green vegetation, such as grass and mangold or chard, spinach and can eat many kilograms of them, given their size and dietary needs.
