How to Identify a Beauty Rat Snake: Appearance and Description

The beauty rat snake is quite long, reaching nearly 6 feet long among some subspecies. There are even one subspecies that can grow up to 7 or 8 feet long. The biggest one on record was just under 9.2 feet long, named Obi One Kenobi. The body of the beauty rat snake ranges from yellowish-brown to an olive green hue, though the tail is darker than the head. Along the back, you’ll see two pairs of black spots, though the head and neck have no pattern. In a crisp line that starts at the back corner of the eye, the stripe goes all the way across the mouth to the same place on the other side of the head. The mouth instead is a pale cream color.

With so many different species, their coloration can change between the species. The Chinese beauty snake, for example, is usually on the yellow side, but it may be white or albino as well. The Japanese rat snake, however, is completely white, featuring the typical red-eye associated with albino snakes.
