''Austropyrgus'' is a genus of minute freshwater snails with an operculum (gastropod), operculum, Aquatic animal, aquatic gastropod molluscs or micromolluscs in the Hydrobiidae family (biology), family. ''Austropyrgus'' species are endemism, endemic to Australia, where they are found in virtually all freshwater habitats, from high mountain streams to isolated Spring (hydrology), springs in the arid zone. Species With 76 recognized species, ''Austropyrgus'' is the largest genus of Australian freshwater molluscs and is the most widespread of the Australian freshwater ''Hydrobiidae'' genera. ''Austropyrgus'' species include: * ''Austropyrgus abercrombiensis'' Clark, Miller & Ponder, 2003 * ''Austropyrgus angasi'' (E. A. Smith, 1882) * ''Austropyrgus aslini'' Clark, Miller & Ponder, 2003 * ''Austropyrgus avius'' Clark, Miller & Ponder, 2003 * ''Austropyrgus buchanensis'' Clark, Miller & Ponder, 2003 * ''Austropyrgus bullerensis'' Clark, Miller & Ponder, 2003 * ''Austropyrgus bungoni ...

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 ...
