Identification:
This snake species is small in size. It has a flattened head with two barbels, each approximately 1 cm long, located anteriorly. The scales are smooth, and the belly is relatively small. Coloration and patterns are highly variable, often featuring dark brown blotches on the body. The ventral surface is typically yellowish-brown, particularly in still freshwater habitats with acidic conditions. Some individuals exhibit a pale yellow color with faint stripes on the flanks and two dark stripes running along the dorsal side.
Habitat and Ecology:
This snake inhabits lowland areas, wetlands, and environments abundant with ponds and marshes. They are typically active and forage during the day. They often lie motionless, using their barbels, which extend from their snout, to lure prey. They ambush small prey, including fish, shrimp, and other small animals, which they wait to approach. Each brood contains 5-13 offspring. Newborn snakes measure 20-24 cm in length and resemble adults.
Distribution:
- Vietnam: Song Be (Thu Dau Mot), Tay Ninh, Long An (Tan Thanh, Long An), Kien Giang (Ha Tien)
- Global: Southern part of the Indochinese peninsula, including Cambodia and Malaysia.
Conservation Status:
The species is still relatively common in the Mekong Delta. However, it is experiencing increased capture and trade, which places its population at risk.
