Melanochelys tricarinata

The Tricarinate Hill Turtle is a medium-sized freshwater turtle distinguished by three prominent ridges (keels) running along its dark brown to black carapace. Adults typically measure 15-20 cm in length, with females generally larger than males. The species exhibits semi-aquatic behavior, spending time both in water and on land, feeding on aquatic vegetation, fruits, insects, and small fish.

As both predator and prey, these turtles play an important role in maintaining aquatic ecosystem balance.

This species inhabits permanent rivers and streams across parts of South Asia, with populations documented in Bangladesh, northeastern India, and Nepal. They prefer slow-moving waterways with muddy bottoms and abundant vegetation, often in hilly or mountainous regions that give the species its common name.

The Tricarinate Hill Turtle faces severe pressure from multiple human activities. Intensive hunting and trapping for local consumption and traditional medicine use represents the primary threat. Habitat degradation through logging operations along waterways destroys nesting sites and reduces food availability. Additionally, fishing activities and general harvesting of aquatic resources disrupts their ecosystem and can result in incidental capture.

Conservation efforts remain limited, with the species protected under various national wildlife protection acts in its range countries. Some populations exist within protected areas, though enforcement of hunting restrictions proves challenging in remote regions.

The species' outlook remains concerning, with continued population declines across its range. Without enhanced protection measures and reduced exploitation pressure, the Tricarinate Hill Turtle faces an uncertain future.
