SPECIES IN DETAIL
Gray-Banded Kingsnake
Lampropeltis alterna
CONSERVATION STATUS: Least concern
CLIMATE CHANGE:
At the Aquarium
The gray-banded kingsnake is one of the Aquarium’s animal ambassadors brought out periodically for meet-and-greet sessions.
Geographic Distribution
This species is found in Southern New Mexico, northern Mexico, and the Trans-Pecos/Chihuahuan Desert area of southwestern Texas.
Habitat
These snakes live in arid, hot, rocky, mountainous habitats.
Physical Characteristics
The gray-banded kingsnake is a medium-sized snake averaging 3 feet (91 cm) in length. It has a rather wide head compared to other kingsnake species and two large, protruding eyes with round pupils. There are two main color morphs: “blairi” has wide red-orange banding, and “alterna” has thinner orange-red banding. Both have a gray background with black and/or white accenting. Many variations from these basic morphs have been found in both captive and wild specimens, with some lacking the red or range banding completely.
Size
Average length for this species is 3 feet (91 cm). Some may grow up to 4 feet (120 cm) long.
Diet
This snake feeds mainly on lizards. It will also feed on frogs, small rodents, other snakes, and eggs of ground-nesting birds.
Reproduction
Gray-banded kingsnakes exhibit little sexual dimorphism. They breed after winter hibernation. The breeding process typically takes about thirty days to produce eggs. The female usually lays between four to thirteen eggs which will hatch in approximately nine weeks. Hatchlings range from 7 to 12 inches (18 to 30 cm) in length.
Behavior
This secretive, nocturnal snake is rarely seen by humans due to its nocturnal nature and often inaccessible habitats. They have a non-aggressive, docile demeanor.
Adaptation
The gray-banded Kingsnake withdraws to underground homes during long, hot, drought-filled summers to prevent dehydration.
Longevity
This snake lives fifteen to twenty years.
Conservation
IUCN lists this species as Least Concern.
