This species is medium-sized, with a slender body covered in keeled (ridged) scales that give it a rough texture. Its coloration typically varies from brown to olive, with dark patterns running along its body. These markings provide excellent camouflage in its natural habitat.
The rough-scaled water snake is primarily found in slow-moving or stagnant freshwater bodies such as rivers, lakes, marshes, and rice fields. It thrives in humid environments with abundant vegetation, offering both shelter and hunting opportunities.
Being a carnivorous species, Xenochrophis asperrimus primarily feeds on small fish, amphibians, and aquatic invertebrates. It uses its agility and quick reflexes to catch prey in the water, often ambushing unsuspecting victims with swift strikes.
Like many water snakes, Xenochrophis asperrimus relies on its cryptic coloration to blend into its surroundings and avoid predators. When threatened, it may flatten its body and display defensive behaviors such as hissing or striking. If necessary, it can quickly retreat into the water for safety.
This species is oviparous, meaning it lays eggs. The female typically lays a clutch of eggs in hidden, moist locations near water. After hatching, the young snakes are independent and begin hunting small prey almost immediately.
As a predator of small aquatic animals, Xenochrophis asperrimus helps regulate populations of fish and amphibians in freshwater ecosystems. It also serves as prey for larger predators, contributing to the food web.
There is limited information on the conservation status of Xenochrophis asperrimus, but habitat destruction and water pollution pose potential threats. Protecting wetland environments is crucial to ensuring the survival of this species.
The rough-scaled water snake is a fascinating yet often overlooked species that plays a vital role in freshwater ecosystems. With its unique appearance, efficient hunting techniques, and adaptability to aquatic habitats, Xenochrophis asperrimus remains an important part of the biodiversity in its native regions.
