Sumatran short tailed python are found on Sumatra in the western and southern parts of the island. They range in color from dusky/light brown to jet black with black or grey heads. Hatchlings are often more light in color and darken up with age. Healthy adults can reach lengths up to 180-220cm and weigh up to 10-20kg. They are a very “heavy-bodied” snake and truly impressive.
