Armadillo Herd

Armadillos have a unique reproductive scheme. Only one egg is fertilized. That egg divides and the resulting two eggs also divide once. Hence, a normal armadillo litter is always identical quadruplets.

Adult armadillos are solitary. After leaving their nest burrow, litter mates remain together for a relatively brief time before going their separate ways.
