The buttermilk racer is a thin-bodied snake, capable of attaining a total length of 1.52 m (60 inches). Its color is a unique pattern of black, greens, yellows, greys and even sometimes blues, flecked with white or yellow. Their underside is white or cream-colored.
Other common names for Coluber constrictor anthicus include the following: ash snake, blue racer, brown racer, Louisiana black snake, spotted black snake, spotted racer, variegated racer, and white oak racer.[1]
Racers are diurnal, active predators. They are fast moving, and are often quick to bite if handled. They generally eat rodents, lizards and frogs, but as juveniles they will also consume various kinds of soft-bodied insects. They are fairly nervous snakes, and as such, do not typically fare well in captivity. For protection, they release a foul-smelling scent when caught to deter predators. They also thrash around to escape and can unknowingly injure themselves.
