The beauty rat snake (Elaphe taeniura), also called the beauty ratsnake, the beauty snake, or the cave racer, is a species of snake in the family Colubridae. The species is native to the eastern and southeastern regions of Asia. It is a long, thin, semi-arboreal species of snake with several recognized subspecies. This constrictor feeds on rodents, and though it is favored in some locations as a natural pest control or pet, it is also considered an invasive species in other locations.
Living about 15–25 years, the average length of the beauty rat snake (including the tail) is about 4–6 feet (1.2–1.8 m). The overall ground color is yellowish-brown to olive, becoming darker at the end of the tail. The skin on the back of the neck and head are uniform in color and the back is typically marked with two pairs of round black spots that meld together. Starting at the back corner of each eye, a black stripe reaches back to each corner of the mouth which is pale cream around the upper labial area.
Subspecies of this species include: Chinese beauty snake (Elaphe taeniura taeniura) – Native to China. This subspecies... Wikipedia →
