If you guessed that this is a crayfish hole, then you're correct!

Crayfish are known by several different names, including crawfish, crawdads and even a freshwater lobster. Like their cousins the lobsters, crayfish are crustaceans that come in numerous colors such as red, brown, white, dark green, orange or black. These little critters have two pair of antennae, a hard shell, pincerlike claws and four pairs of legs.

So why does a crayfish live in a hole? Well according to our friends at Animal Planet, these mud mounds show up when water is low and the crayfish's mudflat is exposed. These smart creatures dig a hole down to water level, going deeper every time the water recedes. The result is that this muddy ring appears at ground level.

As you most likely already know, crayfish are a popular delicacy among Cajuns and other Southern folks. However, did you realize that crayfish aren't just indigenous to the South? In fact, they are found around the globe. There are about 500 species, with 350 of those found here in North America. So no matter where you go, we bet you'll be able to satisfy your cravings for these yummy mudbugs.
