@kpixtv: Baby capybara siblings make their debut at the San Francisco Zoo! This marks the first time in nearly a decade zoo visitors will see capybaras. These six-month-old pups came from the Sacramento Zoo. Capybaras are the world’s largest rodents and native to Central and South America. The capybaras don’t have names yet because the zoo is holding a fundraiser where it plans to auction off naming rights for the siblings.
