Ostracods are small, bivalved aquatic crustaceans that secrete shells of low magnesian calcite. Adults are typically 0.5 to 3 mm long. Ostracods are common in all types of non-marine waters with neutral to alkaline pH. They are frequently abundant and well preserved in lake sediments. Ostracods may also occur in slightly acidic waters, but their shells are rarely preserved in the sedimentary record in such environments.
