The capybara is extreme in being the largest living rodent, but is even more extreme in its efficiency of food-processing. What is not generally realised is that the capybara chews with the largest ever-growing cheek-teeth of any living animal on Earth, and is the largest living animal that routinely recycles its own faeces to digest them a second time.
