Boiga cynodon

It is a large snake, reaching more than 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, sometimes uniformly colored or marbled with brown. This species may possess a potent neurotoxic venom; however, the effects have shown to be reversible with neostigmine, suggesting that envenomation from this species is treatable with anticholinesterase therapy. ==Diet==

It feeds mainly upon small vertebrates such as birds and bird eggs but may also take lizards and small bats. ==Reproduction==

Boiga cynodon is an oviparous species, with sexually mature females laying eggs, 6-12 per clutch. In this species, it is suspected that improper incubation temperature and/or humidity can result in the death of embryos or the emergence of young with spinal deformities. == Habitat ==

The dog-toothed cat snake is found in a wide range of habitats, from primary and secondary forest to cultivated areas, rural gardens and urban areas. It is often found in coconut plantations. In forested areas, it is known to live in the canopy. Boiga cynodon is occasionally killed by vehicles, as evidenced by reports of roadkill incidents. It has also been recorded being sold in some online groups in the Philippines. ==Geographic range==

Boiga cynodon is a widespread species in Southeast Asia, ranging from southern Thailand into Peninsular Malaysia (including Pulau Tioman) and Singapore, extending south into Indonesia as far as Bali (including the Mentawai Archipelago, Sumatra, Nias, the Riau Archipelago, and Java). It is also found on Borneo (Brunei, Kalimantan, Sabah, and Sarawak) and throughout the Philippines, including the islands of Basilan, Culion, Dinagat, Leyte, Luzon, Mindanao, Palawan, Polillo, Sibutu, Panay, Samar, and the Sulu Archipelago. Records from the Lesser Sundas east of Bali, including Sumbawa and Flores, refer to the closely related Boiga hoeseli. It is typically found from near sea level up to around 600m in the Philippines. The presence of this species in Myanmar is uncertain. ==References==
