THE Chinese softshell turtle (Pelodiscus sinensis) is a medium-sized turtle with a distinct softshell carapace. Its shell, with a pliable and leathery texture, varies in coloration but is typically brown or olive, often adorned with intricate patterns. Its head is relatively large and features a long snout. Its webbed feet help it move swiftly in water.

They are primarily found in freshwater habitats like rivers, lakes, ponds and marshes. In Shenzhen, these turtles can be seen basking on rocks or on submerged logs along the banks of water bodies, such as those along the Dasha River or in Wutong Mountain. They prefer areas with abundant vegetation and ample sunlight, where they can nest and bask.

Having a diverse diet, they primarily feed on aquatic plants, insects, crustaceans, small fish, amphibians and mollusks. Their long snouts help these efficient hunters to swiftly snatch prey from the water. Their varied diet contributes to their adaptability and survival in different ecosystems.

Breeding season is usually during the warm months, typically from April to August. Females lay their eggs in sandy or gravelly areas near water. A single clutch can contain up to 20 eggs, depending on the size and maturity of the female.

This turtle plays a crucial role in the local ecosystems. As an omnivorous species, it helps maintain the ecological balance by controlling populations of aquatic plants, insects, and small vertebrates. These turtles serve as prey for larger predators, contributing to the food chain dynamics within their habitats. Their presence is an indicator of a healthy aquatic ecosystem.

However, some introduced turtle species pose a potential threat to the local turtle population, competing against them for food and nesting sites. Another concern is the possible interbreeding between native and introduced species, which leads to hybridization and potentially harms the genetic integrity of the local population.
