About the Dog-toothed Cat Snake

Boiga cynodon, commonly known as the dog-toothed cat snake, is a nocturnal species of rear-fanged colubrid snake endemic to Asia. It is a large snake, reaching more than 2 m (6+1⁄2 ft) in total length. The front teeth of the upper jaw and the lower jaw are strongly enlarged. The anterior palatine teeth are significantly enlarged, while the posterior chin shields are larger than the anterior ones.

The dorsal scales are smooth and arranged in 23 or 33 rows at midbody, with the scales in the vertebral row being notably enlarged. The species has 248 to 290 ventral scales and 114 to 165 subcaudal scales. Boiga cynodon can be distinguished from other similar species by several key characteristics. It is slender and laterally compressed. Notably, it has a post-ocular stripe that is distinctly wavy or irregular, unlike the more even or nearly even upper and lower lines found in other similar species. Although coloration can vary, B. cynodon typically features a yellowish or pale reddish-brown dorsal coloration with dark brown or black transverse spots or crossbars. It also has a dark postocular streak of irregular thickness on each side of the head, and its belly is yellowish... Wikipedia →
