Kids' Species Information

Giant Kangaroo Rat: Dipodomys ingens

STATUS

Endangered. This means that the species is in danger of dying out.

DESCRIPTION

Giant Kangaroo Rat on man's armGiant kangaroo rats have sandy-colored fur. Their bellies are white. They have a white stripe across their hips. There is a tuft on the end of the tail.

Adults are 31-35 centimeters long. (About 13 inches) This includes a 16-19 cm tail. (About 7 inches.) They weigh 130-180 grams. (About 5 ½ ounces) They are the largest kangaroo rat.

Kangaroo rats are not what you think of as rats. They are not like common household rats.

Why "Kangaroo"? They hop on their hind feet like a kangaroo.

FOOD

Mainly seeds. Also green plants and insects. They forage at night.

Kangaroo rats can survive without water. They convert seeds into water. They don't sweat or pant to keep cool. They live in burrows and come out at night. Their kidneys produce very little urine. Maybe we should call them "camel rats"!

HABITAT

Dry, sandy grasslands.

MATING

January to May. Litters average 3 babies.

PREDATORS

Barn and Great-Horned Owls. Coyotes, Kit Foxes and Badgers. Rattlesnakes, Gopher Snakes, King Snakes and Coachwhips.
