On a recent trip to Mississippi, I stopped to look at a freshly killed roadkill snake (I didn’t hit it). It turns out it was a speckled kingsnake (Lampropeltis getula holbrooki). The snake is black with flecks of yellow through and a yellow belly. They can reach up to 132 cm long (51 inches). The one I found looked almost green. They are also called the salt-and-pepper snake for their unique coloration and commonly kept as pets due to their beauty. Apparently, you can buy one online for 60 dollars. However, they often bite and it’s unclear if their populations in the wild are steady. They will also rattle their tail when threatened to mimic a rattlesnake, and spray musk from their scent gland. This musk is actually used to let other snakes in the area know that there is danger.
It’s one of the eight subspecies of the eastern kingsnake (Lampropeltis getula). Kingsnakes are a type of racer snake, and kill their prey via constriction which you would be able to guess if you looked at their heads and how small their jaws are. They are found throughout the united states and even in Baja Mexico. They prefer to live in grassland, swamps, and near streams. They have really varied diets and will even eat other snakes. They have evolved to clamp down on the jaws of other snakes to avoid being bitten by a venomous one but even if they are bitten they are immune to the venom as well. Because they eat and kill venomous snakes people tend to really like kingsnakes and even state they are protecting the neighborhood. Snakes also help to reduce the populations of rodents and other “nuisance” animals.
Interestingly, the Alabama Department of conservation and natural resources says there is a high conservation concern for the snake as the past 30 years have led to rapid declines in populations for unknown reasons. It is suspected that red ant prey on the young and eggs of the snakes and contributed to their decline. Declines are also thought to be related to the logging of hardwood trees in the area. The Mississippi deparmtent of wildlife, fisheries, and parks did not have any information on the snake. Kingsnakes are also eaten by alligators, striped skunks, and possums.
