The Mexican black kingsnake is a sleek, jet-black member of the common kingsnake group from northwestern Mexico. Its mirror-like scales and bold appetite have made it one of the most recognizable kingsnakes in the hobby. This guide covers what to expect as an owner and how to choose a healthy-looking, well-started snake.
Adult Mexican black kingsnakes are solid black from head to tail, with a high-gloss sheen that shows blue or purple highlights in good light. The belly is usually black or very dark gray. Hatchlings sometimes show faint light flecks or traces of a pattern, which typically darken and disappear with age.
They belong to the common kingsnake complex, and you will see them listed as Lampropeltis getula nigrita or simply Lampropeltis nigrita, depending on which classification the seller follows.
In the wild, these kingsnakes live in the arid and semi-arid lowlands of northwestern Mexico, with a range that reaches toward the Arizona border. Their dark coloring stands out against the pale desert-edge landscape, and they are most active around dawn, dusk and after rain.
Adults usually measure 3 to 4 feet in length and have a solid, muscular build. They grow steadily for the first few years and then slow down once mature. With good husbandry, a Mexican black kingsnake commonly lives 15 to 20 years.
That long lifespan makes simple record-keeping worthwhile. Husbandry.Pro is a handy way to log feedings, sheds and weights, so you have a clear history if your snake's appetite or growth ever changes.
Give your kingsnake a secure enclosure with a warm side, a cooler side and a hide at each end, plus a sturdy water bowl. Kingsnakes are strong and persistent, so a well-latched lid is essential. Moderate humidity works well, and a humid hide helps with shedding.
In the wild, Mexican blacks eat rodents, lizards and other small vertebrates. In captivity they do well on frozen-thawed mice and later larger mice or small rats, and they are known for eager feeding. As with all kingsnakes, house them alone, since they will eat other snakes. Young snakes may be jumpy at first, and regular, calm handling usually produces a steady adult. The ReptileAds care guide has detailed ranges and schedules.
Because Mexican blacks look so similar, focus on the information behind each listing. Check the hatch date, sex and feeding notes, and look for clear photos that show a clean shed and bright eyes.
Use built-in chat to ask the seller how many meals the snake has taken and what they know about the parents. Review seller profiles and reviews, and save a Hit List alert if you want to hear about new listings. If you would like to compare other kingsnakes, the California, Eastern, Gray-Banded and Other Kingsnakes categories are close by.
