Farancia is a genus of colubrid snakes. It consists of two species, one commonly referred to as the rainbow snake (F. erytrogramma) and the other commonly referred to as the mud snake (F. abacura). Both species are native to the southeastern United States.
Description
Adult specimens of Farancia species are usually to 36-54 inches (92–137 cm) in total length (including tail).[1] They are usually dark brown or black dorsally, with a brightly colored underside that is red or orange. Rainbow snakes exhibit red striping down their backs.
The body of Farancia species is cylindrical, robust, and muscular. The smooth, shiny, and iridescent dorsal scales are arranged in 19 rows at midbody. The tail is short, ending in a spine.[2]
Behaviour
Snakes of the genus Farancia are semiaquatic, living in the muddy edges of slow moving, permanent water sources.
Diet
The diet of Farancia species consists primarily of amphiumas, eels, and sirens.
Reproduction
In Farancia breeding occurs in early spring, and eggs are laid in a burrow near the water in early summer. The clutch incubates between 8–12 weeks, and hatches in mid-autumn.
