Xenochrophis piscator, commonly known as the water snake or the Indian water snake, is a non-venomous species found primarily in freshwater habitats across South and Southeast Asia. It belongs to the family Colubridae and is characterized by its slender, elongated body, which can reach lengths of up to 1.5 meters. The coloration typically features a combination of dark brown or grayish scales, often with lighter mottling or bands, providing effective camouflage in its aquatic environment.

This species is adept at swimming and is often seen basking near the water\'s edge. Its diet mainly consists of fish and amphibians, which it captures using its agile movements and sharp reflexes. Xenochrophis piscator is primarily diurnal, active during the day, and prefers habitats such as rivers, lakes, and marshes.

Reproductively, it is oviparous, laying eggs in moist environments, which hatch into fully formed young. While generally non-aggressive, the water snake may exhibit defensive behaviors if threatened. Its ecological role as a predator helps regulate fish populations, contributing to the health of freshwater ecosystems. The adaptability and widespread distribution of Xenochrophis piscator make it an important species in its natural habitat.
