Amazonian marsh rat
They have short fur, which is tawny or buff over the back, becomes paler on the flanks, and fades to white or pale orange on the underparts.[4] Amazonian marsh rats are found across much of northern South America east of the Andes.[1] They inhabit open areas such as grasslands, savanna, marshes, clearings in the rainforest, and farmland, at elevations up to 2,000 metres (6,600 ft).[4] Predators include caimans, rattlesnakes, barn owls, hawks, kites, and probably crab-eating foxes.The female gives birth at night or at dawn to a litter of up to eight blind, hairless, pups, each measuring around 5 cm (2.0 in) and weighing 7 g (0.25 oz).
