- Scientific Name
- Lampropeltis getula nigrita.
- Species Name Meaning
- Part of the “kingsnake” group—named because they can eat other snakes, even venomous ones; “black” refers to their jet-black, glossy coloration.
- Size & Lifespan
- 3–4 feet on average, occasionally up to 5 feet. Lifespan 15–20+ years in captivity.
- Native Range
- Found in Sonora and Sinaloa regions of northwestern Mexico.
- Habitat
- Arid desert, scrublands, rocky areas, and semi-dry forests.
- Behaviors
- Curious, active, strong feeders. Can rattle tail, musk, or bluff-strike when stressed.
- Social Structure
- Solitary—only together for breeding.
- Activity Cycle
- Diurnal with crepuscular tendencies, more active early morning and late afternoon.
- Why They Look This Way
- All-black coloration helps regulate heat quickly in cooler desert mornings and provides camouflage.
- Fun Facts
- Known for immunity to some venom; excellent escape artists; one of the most popular kingsnake morphs due to their solid, sleek black look.
Enclosure
- Ideal Size
- Minimum 40-gallon (36”x18”x18”) for adults; larger preferred due to activity level.
- Substrate
- Cypress mulch, aspen, or a mulch blend that allows burrowing. Cypress is safe and helps maintain humidity.
- Temps/Humidity
- Basking spot 88–90°F. Cool side 72–75°F. Warm hide 80–82°F. Humidity 40–60%. Provide a humid hide for shedding. UVB optional but beneficial for natural rhythms.
- Temperature Tolerance
- Ideal ambient range 75–85°F. Can tolerate brief drops to 68–70°F and short peaks to low 90s, but avoid extremes.
- Notes
- Secure lid—excellent escape artists. Provide hides on both warm/cool sides and climbing branches.
Diet and Hydration
Feeding Schedule
- Juveniles (under 2 ft)
- 1 appropriately sized mouse every 5–6 days.
- Subadults
- 1 adult mouse every 7 days.
- Adults
- 1 small rat or XL mouse every 10–14 days.
- Avoid overfeeding—MBKs grow fast and can become overweight.
Food Options
- Staples
- Frozen-thawed mice, rats.
- Treats
- Quail chicks, reptilinks, small birds, occasional eggs (rare).
- No Feed/Toxic
- Wild-caught rodents, live prey (unless necessary), lizards from outside sources.
- Hydration
- Fresh clean water daily in a sturdy bowl large enough for soaking.
- Supplements
- None typically needed—whole-prey diet provides complete nutrition.
- Diet Behaviors
- Kingsnakes may display aggressive feeding response; open enclosure slowly during feeding days.
Health
Concerns
- Common reptile parasites (worms, mites) if hygiene is poor.
- Inclusion Body Disease (rare in kingsnakes but possible via exposure to boas).
- Respiratory infections if kept too cool.
- Stomatitis (“mouth rot”) if humidity/temp are off.
Overall a hardy species if husbandry is correct.
Handling
- Temperament
- Generally handleable and calm when accustomed to people. Juveniles may be flighty or musky.
- Stress
- Can stress if overhandled daily; short frequent sessions help tame them.
- Handling Tips
- Support full body, avoid fast movements, let snake move through your hands. Do not handle during shed or right after eating.
- Show Suitability
- Yes—Mexican Black Kingsnakes are one of the BEST show snakes. Calm, not too big, visually striking, rarely messy, great with kids once accustomed to handling.
Requirements for Show Animals
- Friendly & handleable
- Yes
- Not messy
- Usually very clean; low poop frequency
- Can do 5+ shows/day: Yes
- Can be boxed over a day
- Yes, with ventilation and proper temps
- Good with heat
- Yes, as long as temps stay 75–90°F
