Meet the Black-headed or Royal Rat Snake

This is an adult Royal Rat Snake. By Dick and Patti Bartlett Of the Diadem Snakes, it is Spalerosophis atriceps the Black-headed or Royal Rat Snake that is most sought by hobbyists. A pretty but quietly colored snake, the ground color may vary from sand gray to orange. It has irregular dark blotches and spots both dorsally and laterally. The spotting may be reddish on juveniles but darkens as the snake ages. The head may be black or black and tan dorsally and the face may be orange to red, with or without black. The belly may be unmarked white or small dark blotches may be present. These snakes are weak constrictors at best, and often smother live prey, such as a mouse, by grasping and holding it by the nose while laying body coils atop the rodent. This snake may bite if carelessly restrained or otherwise frightened. Adults may exceed 6 feet by a few inches. Hatchlings are 12 to 14 inches long. Once commonly bred in the USA, the Royal Rat Snake is now rather infrequently seen. Many who have successfully bred this species have provided a several weeks winter brumation with temperatures in the mid 50sF. A clutch normally contains between 3 and 12 eggs. India and Pakistan comprise the range of this snake.

The amount of black pigment can vary both individually and with age.
