Dasypus novemcinctus
The nine-banded armadillo wears bony armor plates and can hold its breath for six minutes to walk across stream beds. Every litter consists of four genetically identical quadruplets from a single fertilized egg. It digs for ants and termites with powerful claws and shelters in burrow systems it may share with other animals. Its range has expanded steadily northward through the twentieth century, and it is now common in Texas and Florida.
