Mexican Black Kingsnake
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 & 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.
