What speciality is in giant rat when compare to other rats ?
A giant rat is a rat that is substantially larger than its other rodent cousins. Rodents of unusual size, do appear in nature such as the Capybara Hydrochoerus hydrochaeris, Gambian Pouched Rat, Cricetomys gambianus, adult specimens of which have been known to attain upwards of 3 feet (91 cm) in size from nose to base of tail; and the caviomorphs of South America regularly top the scales at over 200 lb (90 kg) in weight.
