Soft-shell turtles are a unique group of turtles known for their flexible, leathery shells instead of the hard, bony shells found in most turtles. They belong to the family Trionychidae and are primarily found in freshwater habitats like rivers, lakes, and ponds. Their soft shells help them move more easily in the water and can also provide some camouflage against predators. These turtles have long necks and can breathe through their skin, allowing them to stay submerged for extended periods. Soft-shell turtles are omnivorous, feeding on a diet that includes aquatic plants, insects, and small fish. They play an important role in their ecosystems by helping to control the populations of their prey.
