Cemophora coccinea

Species of snake

Cemophora coccinea, commonly known as the scarlet snake, is a species of nonvenomous snake in the family Colubridae. The species is native to the southeastern United States. There are two subspecies of C. coccinea that are recognized as being valid. The Texas scarlet snake (C. lineri) was previously considered a subspecies.

The scarlet snake is relatively small, growing to a total length (including tail) of 14 26 inches (36–66 cm) at adult size. The dorsal pattern consists of a light gray ground color, with a series of black bordered red, white or yellow blotches down the back. The belly is either a uniform light gray or white color. The dorsal blotches can extend down the sides of the body, appearing somewhat like banding or rings, which sometimes leads to confusion with other sympatric species such as the venomous coral snakes or the harmless scarlet king snake. The similar pattern exhibited by these three snakes is a form of mimicry known as batesian mimicry. This is a phenomenon in which members of a palatable species gain protection from predation by resembling or mimicking the defensive signaling of an unpalatable or defended species.

The generic name, Cemophora, is derived from the Greek words Kemos, meaning "muzzle", and phoros, meaning "bearing", referring to the pronounced rostral scale characteristic of members of the genus.

C. coccinea is found only in the United States. They are endemic to peninsular Florida, and found in southeastern Texas, eastern Oklahoma, Arkansas, parts of Louisiana, Mississippi, Alabama, Georgia, South Carolina, North Carolina, Tennessee, Kentucky, Illinois, Indiana, Virginia, Maryland, and Delaware; with disjunct populations in New Jersey and central Missouri. The species is more commonly found throughout most of the Atlantic coastal plain areas. They prefer open forested areas with sandy soil, ground litter, and organic debris. In New Jersey, the scarlet snake has been recommended by the New Jersey Endangered and Nongame Advisory Committee that it be put on the threatened status for this species within the state, but no formal rule proposal has been filed to date. The Threatened status is largely due to population declines and habitat loss. Reasons for the decline in their population are a loss of habitat, illegal capture for the pet trade, road mortality, and direct killing.
