In our neck of the woods: Centipedes

It's late March, and things are warming up here. After seeing very few invertebrates during the winter months, Trish and I were on a hike a few days ago, and she spotted what may be the largest centipede we have found in Missouri. It was about 3 inches (7.6 cm) long and seemed to be on the prowl, roaming around looking for prey (FIRST PHOTO).

FYI—centipedes and millipedes are very different. Each group makes up its own Class, which means they are as different from each other as a human is from a fish, or from a snake.

Centipedes, with one pair of legs per body segment, are fast-moving predators. Millipedes, with two pairs of legs per body segment, are slow-moving grazers. If a millipede is like a gentle brontosaur, a centipede is a vicious T-rex.

Near the head (the business end) of a centipede is a modified pair of legs (called forcipules) that act as fangs, injecting venom that quickly paralyzes prey. In fact, a "giant centipede" (those in the genus Scolopendra) that weighs only 3g can immobilize a 45g mouse in less than 30 seconds. Most smaller centipedes, of course, eat small invertebrates, but "giant centipedes" can prey on lizards, snakes, rodents, birds, and even bats.

The centipede we found on our hike (the first photo) is not considered a "giant centipede." However, for many years, Trish and I have regularly hiked the Flint Hills of eastern Kansas, where we often find the tiger centipede (Scolopendra polymorpha). This beast grows to SEVEN inches (18cm) long. The SECOND PHOTO is a tiger centipede we found in 2011.

I have to tell you a brief story. Back when we were both biology teachers, we captured the largest tiger centipede we could find so that we could show it to our students. We put it in a plastic butter tub, and when we got home, we decided to transfer the creature to a larger container. This did not go well. The centipede made a wild lunge at the stick I was using to coax it from one container to the next. This startled me, and I dropped the butter tub. The centipede took off across the living room floor and disappeared down a crack next to the stairs.

It was under the floorboards of the house—the house where we lived, slept, and routinely walked around without shoes. We never saw the centipede again, but we found it somewhat more difficult to relax for several weeks after the centipede incident.

By the way, the tiger centipede is not particularly dangerous to humans, but a bite would be extremely painful. Other species of giant centipedes can be more dangerous. One of the largest of the giant centipedes, the Amazonian giant centipede, grows to 12 inches (30cm) long.

Okay, one more morsel of information to satisfy your burning curiosity. Giant centipedes are not considered as food for humans in many cultures. But in some countries, including China, Thailand, Vietnam, and Cambodia, they are sometimes eaten grilled or deep-fat fried and are usually served on skewers, like you see in this the THIRD PHOTO.

Oh... and one more thing: the giant centipede was actually my inspiration for the venomcrook, a nasty living weapon wielded by an alien creature in Bridgers 3: The Voice of Reason. Trust me... you don't want to get hit with a venomcrook. FOURTH PHOTO.
