Our First Armadillo

Warning: This post contains some roadkill photos. Heck, it's a post about armadillos. If it didn't mention roadkill, it wouldn't be about armadillos now, would it? Let's get that first DOA 'dillo out of the way:

There, that wasn't so bad. This poor fella managed to get himself killed in a beach parking lot. That takes some doing on both killer and killee's parts. Armadillos would be OK if they'd crouch down when a car passes over them, but instead they startle and jump straight up, bonking against the chassis and essentially commiting suicide. Armadillos are capable of leaping 4' straight up into the air, so you can imagine the forces when this power is applied to a speeding automobile.

I have always, always wanted to see an armadillo in the wild. Any armadillo (and there are 20 species worldwide, all but one of them in Latin America). In the southern US, we are blessed (or cursed, depending on who you ask) with a single armadillo species, the nine-banded Dasypus novemcinctus.

It's just so cool to have an edentate in the United States. "Edentate" means "toothless," though the nine-banded armadillo is hardly toothless. Here are the weird blade-like teeth of the hapless roadkill I found and examined in Florida. They stood up like an edge cut with pinking shears, more crenulations than teeth. Gross, I know, but look at the teeth, please.

 

Seriously: having an edentate in the US is like our having a flamingo, a spoonbill, an antelope, a lion. It's a lone representative of a cool order we might not otherwise have. D. novemcinctus ranges from Argentina to the southern United States, and it seems to have relatively recently colonized the US, having first been seen here in 1849. Armadillos naturally colonized Florida, but became extinct for unknown reasons. Modern Florida nine-banded armadillos are thought to descend from a pair that escaped from a roadside zoo about 50 years ago in Cocoa, as well as at least one earlier release. Knowing they aren't exactly "native," even if they were historically in Florida, seems to give some people license to hate them. Lots of people hate any animal that digs huge holes, so the cards are definitely stacked against the little armored one. Of all the world's species of armadillos, only the nine-banded has managed to thrive and extend its range. Go novemcinctus!

In deference to Floridians who will doubtless give me their $.02, it's easy to love an animal when it's not excavating your back yard.

But get this: The giant armadillo, Dasypus bellus, once ranged as far north as the Ohio River Valley!! No wonder I was so hot to see an armadillo, even if only its smaller cousin.

Armadillo Online is an amazing compendium of cool armadillo information. Like this: The nine-banded armadillo has a unique salivary bladder surrounded by muscle, a tappable reservoir of gluey saliva that it uses to snare ants, termites, and other insects as it eats.

Did you know that armadillos always have four young, and they are all identical, all the same sex and genetically alike? All four come from the same egg, which divides into four embryos. This makes them good lab animals, because where else are you going to get four genetically identical siblings every time? You've got your experimental animals and your control in one litter. However,  though they quickly become tame, they don't do very well in captivity.

They're also sought after and captured because armadillos can catch and carry leprosy, so a great deal of what we know about transmission of this disease comes from armadillo research. People go out with nets and catch 'dillos and sell them to labs. Unfortunately, people who handle a lot of armadillos sometimes get leprosy from them, yuccch. The armadillo has a weak immune system and an extraordinarily low body temperature -92 to 95 degrees, which is thought to make them susceptible to leprosy. Reason enough not to keep a pet armadillo!

Leprosy, a dreadful lesiony lumpy skin disease caused by the bacteria Mycobacterium leprae and M. lepromatosis, is now treatable with a multi-drug regime of rifampicin, dapsone, and clofazimine given over 12 months. However, the Third World still hosts leper colonies where people suffering from the disease are segregated--over 1,000 colonies exist in India alone. I flew over an island that's given over to people suffering from leprosy in Guyana, in South America. It's still part of the reality for many less affluent countries. That hit me hard, circling over that island just an ocean away from Florida, but decades removed in medical advancement. We are incredibly fortunate in the U.S. I try never to forget that.

Armadillos sleep up to 16 hours a day. Maybe this is why I'd never seen one until this trip to Florida. I've been all over south Texas too, but no go until now. As the kids and I headed to the beach one evening, I saw the trundling shape of my first 'dillo near a busy intersection. I whooped with joy and pulled over to document it.

Absolutely beautiful it was, a perfect specimen.

I was impressed by its muley ears and perfect carapace; its birdlike snoot and tiny eyes. It spent 90 per cent of its time with its nose deep in the grass, looking for insects to eat, so I have dozens of photos but only a few where you can see its little eye. This is one of them.

More armadillo exploration anon.
