Mexican black kingsnake
In the wild, most kingsnakes are moderately sized, reaching an average length of 90-120 Centimeters (3–4 feet), and tend to be plump and stocky in girth. However, in captivity, some kingsnakes can exceed 1,5 Meters (5 feet). This is most likely attributed to the larger and more stable diet they receive in captivity, compared to what they might receive in the wild. These snakes can weigh up to 1,3 Kg (3lbs). as they reach adulthood (dependant on their size), and can live anywhere between 20 and 30 years.
