Paraprososthenia Levayi
†''Paraprosostenia'' is a fossil genus of prehistoric freshwater snails, Aquatic animal, aquatic gastropod mollusks in the family Pomatiopsidae. Species Species within the genus ''Paraprosostenia'' include: * ''Paraprosostenia minuta'' Annandale, 1919 - type species, fossil of Pleistocene of Namma in northern Burma,Davis G. M., Kuo Y.-H., Elaine Hoagland K., Chen P.-L., Yang H.-M. & Chen D.-J. (1981). "''Kunmingia'', a New Genus of Triculinae (Gastropoda: Pomatiopsidae) from China: Phenetic and Cladistic Relationships". ''Proceedings of the Academy of Natural Sciences of Philadelphia'' 136: 165-193JSTOR The length of the shell is 6 mm. It was found in freshwater lake beds, so it is presumed to be a freshwater species as is the case in all other Triculinae. Davis (1979) classified also four extant species within the genus ''Paraprosostenia''. Later Davis (1981)Davis G. M. (1981).

Animalia
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and the deuterostomes, containing the echinode ...
