They are commonly found in freshwater habitats such as ponds and lakes, where they feed on planktonic organisms like zooplankton and small crustaceans. The nautilus shell, often called the fish body, is composed of a layer of calcium carbonate. The nautilus has four pairs of legs, which it uses to swim through water. Naethes
