Which is the largest rodent in the world?
"31 x 24 cm. Pages: 800 pp. Initially it was intended to publish only one volume on lagomorphs and rodents. But due to the large number of described rodents Lynx Edicions organized a survey from summer to autumn 2015 in which a majority of customers decided in favor of two volumes. The sixth volume is devoted to the lagomorphs and 25 families of rodents, including the hares, pikas, chinchillas, the Laotian rock rat (a living fossil), the capybara (the largest extant rodent), and the diverse group of squirrels. The 60 colour plates are created by Toni Llobet. It covers the"
"Capybara The capybara (""Hydrochoerus hydrochaeris"") is a mammal native to South America. It is the largest living rodent in the world. Also called chigüire, chigüiro (in Venezuela) and carpincho, it is a member of the genus ""Hydrochoerus"", of which the only other extant member is the lesser capybara (""Hydrochoerus isthmius""). Its close relatives include guinea pigs and rock cavies, and it is more distantly related to the agouti, the chinchilla, and the coypu. The capybara inhabits savannas and dense forests and lives near bodies of water. It is a highly social species and can be found in groups as large"

"Josephoartigasia monesi Josephoartigasia monesi, an extinct species of South American caviomorph rodent, is the largest rodent known, and lived from about 4 to 2 million years ago during the Pliocene to early Pleistocene. The species is one of two in the genus ""Josephoartigasia"", the other being ""J. magna"". ""J. monesi"" is sometimes called the giant pacarana, after its closest living relative, the pacarana (""Dinomys branickii"") in the family Dinomyidae. The species may have weighed a ton, considerably larger than any living rodent. The skull of the holotype is long, and the remaining incisor is more than in length. The total"

"Giant hutia The giant hutias are an extinct group of large rodents known from fossil and subfossil material in the West Indies. One species, ""Amblyrhiza inundata"", is estimated to have weighed between , big specimens being as large as an American black bear. This is twice as large as the capybara, the largest rodent living today, but still much smaller than ""Josephoartigasia monesi"", the largest rodent known. These animals were probably used as a food source by aboriginal humans. All giant hutias are in a single family, Heptaxodontidae, which contains no living species; this grouping seems to be paraphyletic and"
"Woolly giant rat The woolly giant rat (""Kunsia tomentosus"") is a species of large burrowing rodent native to South America. No subspecies are currently recognised. The woolly giant rat is an exceptionally large rat, the largest living species of sigmodontine rodent, with short limbs and powerful claws. Nonetheless, individuals vary considerably in size, ranging from in head-body length, with a relatively short tail long. Body weight varies from ; no other sigmodontine species has a maximum weight above . The fur is thick and coarse, with an almost uniform shade of dark grey or brown across the whole of the"

Its congener ""Phoberomys insolita"" was a bit larger still, but it is not known from any reasonably complete remains, thus its size cannot be estimated more precisely. In early 2008, the discovery of ""Josephoartigasia monesi"" was announced, which was even larger. Phoberomys pattersoni Phoberomys pattersoni is an extinct rodent that lived in the ancient Orinoco River delta around 8 million years ago. It was the second-largest of the roughly seven species of its genus. Like many other"

Specimens can grow up to 32 cm (12.6 in) in length from snout to vent, and weigh up to 3.25 kg (7.17 lb). This species has a relatively small habitat range in Cameroon and Equatorial Guinea.

Found in northern South America, it is the largest spider in the world by mass and size, but it is second to the giant huntsman spider by leg-span. It is also called the Goliath bird-eating spider; the practice of calling theraphosids ""bird-eating"" derives from an early 18th-century copper engraving by Maria Sibylla Merian that shows one . Despite the spider's name, it only rarely preys on birds. Unlike other species of spider/tarantula, females do not eat the males during mating. Females mature in 3 to 6 years"
