The common kingsnake (Lampropeltis getula) is distributed throughout North America, ranging from Oregon to Mexico in the western portion of the continent and from New Jersey to the Florida panhandle in the eastern portion of the continent (Krysko, 2002). There are several subspecies of L. getula, which differ in geographic location and appearance. These include L. g. californiae from California, L. g. nigrita and L. g. splendida from northern Mexico and the southwest United States, L. g. holbrooki from Colorado, L. g. nigra from the eastern United States (Bartlett and Tennant, 2000), L. g. floridana from Florida (Krysko, 2002), and L. g. getula ranging from New Jersey to Florida (Krysko and Judd, 2006).

The common kingsnake is a member of Colubrinae. Colubrinae is a diverse grouping of snakes that includes more than 150 genera and 700 species. Colubrines are cosmopolitan except for Australia and live in a variety of habitats, although no species are classified as marine or true burrowers. Colubrines vary greatly in size; the smallest is less than 20cm in length, and the largest is over three meters in length (Pough et al., 2004).

The common kingsnake varies from 76cm to two meters in length. Eastern subspecies are typically longer than western subspecies. Their diet includes turtle eggs, young turtles, snakes (including venomous species), lizards, frogs, salamanders, bird eggs, and small mammals. The species is not poisonous and uses constriction to kill its prey (Bartlett and Tennant, 2000). Although prey suffocate under the pressure of constriction, some authors have suggested that constriction also induces circulatory and cardiac arrest in mammalian species (Moon, 2000). The common kingsnake is capable of eating other snakes that exceed its own body length through bending the vertebral column of its prey into waves (Jackson et al., 2004)!

Reproduction in the common kingsnake is oviparous. Females lay at least one clutch every year. Clutches average between two and 24 eggs with an incubation period of 45-60 days (Bartlett and Tennant, 2000). The common kingsnake is a seasonal breeder with the mating season occurring between March and June (Krysko, 2002).

About the Species

This specimen is a frozen captive bred Lampropeltis egg. Growth was terminated 54 days following oviposition. It was made available to The University of Texas High-Resolution X-ray CT Facility for scanning by Dr. Travis LaDuc of The University of Texas at Austin. Funding for scanning and image processing was provided by a National Science Foundation Digital Libraries Initiative grant to Dr. Tim Rowe.

About this Specimen

This specimen was scanned by Matthew Colbert on 24 October 2003 along the coronal axis for a total of 795 slices. Each slice is 0.0688 mm thick, with an interslice spacing of 0.0688 mm and a field of reconstruction of 32.5 mm.
