Chironius carinatus may grow to 3 meters (9.8 feet) in length. Their body color can range from brown to deep yellow or gold, with the tail being generally darker than the body. The belly is often a bright shade of yellow or orange. In most specimens, body scales have lightly colored centers with darker edges. A light colored stripe runs down the length of the body, fading at the tail. The dorsal scales are in 12 rows.[2]
