Like gerbils and pyramid rats, the Morro Bay kangaroo rats resemble little kangaroos, with well-developed hind limbs for
jumping, short front limbs, and a long tail used for balance while leaping. Their ears are average in size and the hair on their backs varies between brown and yellow, while the hair on their bellies is white. As
nocturnal animals, their eyes are very large. The Morro Bay kangaroo rat is 11 to 13 cm long and its tail measures between 16 and 19 cm. It weighs between 60 and 80 g. The Morro Bay subspecies is the smallest of all subspecies. The male is measured to be 300.4 mm while the females are about 295.1 mm long. == Behaviour ==
