The Copperhead Racer is one of the many common snakes that are found in the forests, rural areas, and paddy fields. It is distinguished from other Malayan racer snakes by its copper-colored head lined with three streaks. Its body is grayish or yellowish-brown with distinct four black stripes at the anterior part of the body. It is a diurnal reptile which hunts actively for birds, lizards and other smaller snakes during daytime. The snake can grow to 230 cm long and produces several clutches of about 5−12 eggs annually with hatchlings measuring 25−30 cm long.

The Copperhead Racer goes into defense when vaguely threatened. It straightens its neck, inflates its throat and vigorously strikes to defend itself. The adult snake has the capability to extend its body to a considerable striking range. However, like other snakes, the Racer is likely to flee rather than fight. When fleeing or fighting are futile, the snake may either play dead or writhe, roll over and partially open its mouth to extend its tongue.
