Capybara

Capybara (Hydrochoerus capybara), sometimes called the Water-hog, a semi-aquatic rodent of the guinea-pig family from the north and east of South America. It is the largest living member of the order. Some that Darwin shot were over 3 ft. long. He says that "from their manner of walking, and colour, they resemble pigs; but when seated on their haunches . . . they reassume the appearance of their congeners, cavies and rabbits." Their skins are of trifling value, and the meat is very indifferent.
