Nine-Banded Armadillo
Nine-Banded Armadillo
Dasypus Novemcinctus
The Nine-Banded Armadillos lifespan is anywhere from 7-20 years in the wild. The longest living armadillo was in captivity and lived 23 years.
The Nine-Banded Armadillo reaches full sexual maturity around 2 years of age but don't reach full maturity until 3 or 4 years old. They will start to reproduce the summer after they are born.
The Nine-Banded Armadillo is found in the southern part of the United States and in South America.
The word armadillo means little armored one.
The Nine-Banded Armadillo will almost always produce four identical young and all of the same sex. The gestation is about 4 months after the embryo is implanted. The embryo will be implanted for 14 weeks before it is fertilized.
The young are born with their eyes open and start walking within hours. The newborn skin is soft but will harden over time .
The young will nurse for about two months but stay with their mother for a few more months after weaning.
Armadillos are loners. The female only keep the males around for mating. The female have large external clitoris but the males scrotum and testicles are internal. Most females will lay on there back to mate.
Armadillo are called a generalist feeder and it uses their sense of smell to track down almost 500 different foods, most are insects, ie; beetles, cockroaches, wasps, fire ants, scorpions, spiders, snails, and grubs. It has to use its sense of smell because their lack of eye sight.
The armadillo prefers warm, wet climates and live in forested or grassland habitats. Small streams are no obstacles for them. They can hold their breathe for up to 6 minutes and swim or 'walk' along the bottom of rivers, or creek beds.
They will make burrows only as wide as they are, 6-7 feet deep, and about 10-12 feet long. They usually have more than one active burrow at any time. The armadillos will use its long claws to dig while its tail holds its back end up so that the hind legs can push the dirt out.
The armadillos closest relative is the Sloth and the Anteater. The Glyptodon was the first armadillo to evolve around 10 thousand years ago. They became extinct when the North and South Americas emerged and large canine and feline predators preyed on them, but for unknown reasons a remarkably smaller version of the armadillo re-established.
Some fossils were found so large that the shell of the Armadillo was up to ten feet long. The South American Indians used them as roofs or tombs.
Here are a few facts about the Nine-Banded Armadillo. They can not roll into a balls and roll away. They can only curl to cover their less protected body parts. The Armadillo is the only animal that has this type of armor.
Lastly, when the armadillo is startled it can jump vertically about 4 feet in the air.
