Adult corn snakes have a body length of 61–182 cm (2.00–5.97 ft).[11] In the wild, they usually live around six to eight years, but in captivity can live to an age of 23 years or more. The record for the oldest corn snake in captivity was 32 years and 3 months. They can be distinguished from copperheads by their brighter colors, slender build, round pupils, and lack of heat-sensing pits
