Capybara with Two Pups, Pantanal, BrazilBack again, everyone’s favorite rodent, the capybara. These are the largest rodents in the world and can grow to about four and half feet long and weight 150 pounds. Females are typically larger than males, and they can have between one and seven pups. This mother was hanging out on the riverbank with her two quickly growing pups. Photographed in the Pantanal of Brazil.
