Species description
Geographical Origin and Habitat: Crotalus mitchellii (commonly known as Speckled Rattlesnake) is native to Southwestern United States and Baja California in Mexico, where it inhabits rocky desert slopes, arid canyons, and boulder-strewn hills.
Taxonomy and Genetics: Belongs to the family Viperidae, genus Crotalus. It is studied for its unique venom genetics and specialized physiological adaptations.
Behavior and Habits: Predominantly terrestrial, solitary, and nocturnal. It spends most of the day camouflaged in leaf litter or under shelters waiting for prey.
Morphology: Adults reach an average size of 95.0 cm. Males typically exhibit longer tails than adult females.
Care, breeding and tankmates
Terrarium Setup: Requires an escape-proof terrarium of at least 200 liters with natural loose substrate and secure hiding spots.
Lighting and Heating: Carnivorous diet consisting of properly sized rodents fed via long feeding tongs. Supplement with vitamins.
Humidity and Hydration: Keep ambient temperatures at 18.0-32.0°C with a basking spot of 33.0°C. Provide low UVB.
Feeding and Supplementation: Solitary species, must be housed individually. Keeping multiple snakes together leads to severe stress.
Compatibility: Breeding is difficult in captivity, requiring a cooling period and careful introduction under supervision.
Health and Common Diseases: Prone to respiratory tract infections if ventilation is poor, and blister disease if the substrate is excessively wet.
