The Order Notostraca, also known as the Tadpole Shrimp, is a group of crustaceans that are characterized by their long, flattened bodies and their large, round eyes. These animals are found in freshwater habitats around the world, and they are known for their ability to survive in dry conditions by entering a state of suspended animation. Synonyms for the Order Notostraca include the Anostraca, which includes the fairy shrimp, the Conchostraca, which includes the clam shrimp, and the Laevicaudata, which includes the tadpole shrimp. All of these groups share similar characteristics and lifestyles, making them important subjects for scientific study and conservation efforts.
