Armored tanks of the mammal world reproduce in multiples of four at CHEC
by Monica Dorken, CHEC Educator
June, 2005


There is a picture of a nine-banded adult armadillo in the CHEC Talk slide program that we offer free to civic groups around the Peace River watershed. We always relate natural phenomena and up-close encounters along with each wildlife photo. For example, an armadillo momma can halt her pregnancy mid-cycle if conditions are poor for feeding her family (like severe drought or flood conditions). She can simply resume gestation when things improve. That useful adaptation is called diapause.

She always gives birth to a litter of four females or

Carnivorous Glider Takes to the Trees

four males from a single egg. Each baby is a genetically identical quadruplet. They rest on a bed of leaves and grass that their mother has gathered, balanced on her hind paws and lowered into the

burrow, tail first. That tail is highly sensitive and feels its way for her.

Yet, the staff at the Alligator Creek Preserve on Burnt Store Road had never really witnessed the above facts. We had frequently watched adult dillos single-mindedly searching the soil for insect sustenance. We had even spotted spring mating chases. Now, can honestly pronounce that we have seen the offspring!

We got a call in the administrative office late one afternoon. It was Martha calling from the Education Building across the compound. The baby armadillos were feeding around the boardwalk to the Watershed Resource Center.

We knew that momma had a nest under that building, because Betty and Jamie (the CHEC ladies who worked in that office) had reported spotting four tiny miniatures of mamma emerging from under the raised portable earlier in the week. Now we all had the chance to abandon computers, faxes and phones to gape at the grazing youngsters thanks to the alert call from Betty’s teen-age son Joe (who volunteered to do maintenance tasks that day). He was working on fixing the trailer lights behind the building when he heard rustling in the leaf litter and spread the word for all to witness nature’s display.

Four six-inch armored mammals busily burrowed snouts into the earth. They were oblivious to seven looming shadows watching with delight. Our conversation, interspersed with louder laughter, never deterred these quads from their mission to appease hunger.

Visitors to the Alligator Creek site often see the leathery, peg-toothed one foraging along the trail. This animal's series

of shell-like plates layered with thick hide are supported from stem to stern (scapula to pelvis, actually) by an intervening set of nine hoops which allow the critter to twist and turn, just as the folds of an accordion allow that instrument to be squeezed and expanded.

One might think that this armored knight is well equipped for jousting, but they are docile creatures who would rather flee than fight, often in a zigzag pattern to elude enemies. But if you are quiet when approaching an armadillo, they will continue their frantic feeding unaware of your presence. Unfortunately, when they are suddenly startled they jump straight up in the air, which frequently causes their demise on the undercarriage of a vehicle that may actually be attempting to avoid hitting the critter.

To cross a stream or pond, the armadillo walks across the bottom as their specific gravity is heavier than water and they can hold their breath for up to six minutes. When a larger body of water needs to be traversed, the “armored tanks" will jump in and dog paddle furiously keeping their snouts above water. Eventually their digestive tract inflates with air so they can float. The longer they stay in the water, the higher they float.

What incredible little creatures. We finally met the whole family. Happy Trails!
