The eastern yellow-bellied racer is a thin-bodied snake, capable of attaining a total length of 1.5 metres (60 inches). As an adult, its color is an olive grey-green with a yellow underside. As a juvenile it is remarkably different, having a tan or cream-colored body with brown or grey blotches. The color gradually changes as the snake ages, becoming solid olive grey-green. Authors disagree as to when this transformation is complete, from 1½ to three years old, and from 18 to 30 inches (46–76 cm) in total length.[4]
Coluber constrictor flaviventris is listed as an endangered species in the province of Saskatchewan.[6]

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.[7]
