speckled kingsnake

The speckled kingsnake (''Lampropeltis holbrooki'') is a nonvenomous species of kingsnake endemic to the United States.

Description

The speckled kingsnake usually grows up to in total length (including tail), but the record total length is . The common name is derived from its pattern, which is black, with small yellow-white specks, one speck in the center of almost every dorsal scale. It is also known as the "salt-and-pepper snake".

Geographic range

The speckled kingsnake is found in the central and southern United States from southern Iowa to the Gulf of Mexico. Its range overlaps that of the desert kingsnake, ''Lampropeltis splendida'', and it is known to intergrade with that species.

Habitat

The speckled kingsnake prefers wetter habitats than other kingsnakes, such as swamps and rivers, but it does commonly venture to dry areas such as woodlands and grassy fields.

Diet

The diet of the speckled kingsnake consists of mammals, birds, rodents, frogs, lizards, and other snakes. It kills by constriction.

Behavior

When threatened, the speckled kingsnake shakes its tail like a rattlesnake to deter predators. It frequently expels musk and feces or bites when threatened. It is usually docile, often striking only one or two times after capture, and is frequently kept as a pet. It is commonly captive bred.

Taxonomy and etymology

This snake was first described by American herpetologist John Edwards Holbrook in 1842. At that time, he called it ''Coronella sayi'' under the mistaken impression that it was the species previously described by Schlegel as ''Coluber sayi''. In 1902, Stejneger pointed out that because ''Coluber sayi'' is a different snake, ''Pituophis catenifer sayi'', the name ''sayi'' could not be applied to this snake. Therefore, he proposed the name ''Lampropeltis holbrooki'', honoring Holbrook.Beolens, Bo; Watkins, Michael; Grayson, Michael (2011). ''The Eponym Dictionary of Reptiles''. Baltimore: Johns Hopkins University Press. xiii + 296 pp. . (''Lampropeltis getula holbrooki'', p. 125). It was for many years considered a subspecies of ''L. getula'', but has been elevated to full species status as ''L. holbrooki''.
