A mostly nocturnal mammal with brownish bony plates covering its head, body and tail. Stomach and ears are soft and sparsely haired. It has long toenails and can dig very fast.
Many animals use abandoned armadillo burrows.
Four young are always born and they are either all female or all male. Primary food is earthworms and arthropods. They scratch surface of soil for insects but in times of drought will dig deep to find insects. Many times they dig up gardens to consume insects during droughts. Extremely common in the park.
