Mischling-shrimps are small, freshwater crustaceans that are native to the rivers and streams of Central Europe. They are similar in appearance to shrimp, but have a flattened, curved body. They are light brown in color with dark spots, and have two pairs of antennae. The body is covered by a hard exoskeleton, which provides protection from predators. They feed primarily on algae and other small organisms, and can be found in shallow areas of rivers and streams. They are a popular food source for many different kinds of fish, and can be collected by hand or with nets.
