Hauffenia Sp. Nov.
''Hauffenia'' sp. nov. is an as yet Undescribed taxon, undescribed (in 2013)Horsák M., Juřičková L. & Picka J. (2013). ''Měkkýši České a Slovenské republiky. Molluscs of the Czech and Slovak Republics''. Kabourek, Zlín, 264 pp. p. 44-45 (in Czech and English). species of freshwater snail that lives underground, an aquatic gastropod mollusk in the family Hydrobiidae. This species is found in List of non-marine molluscs of Slovakia, Slovakia. Taxonomy The genus ''Hauffenia'' is taxonomically problematic.Čejka T., Dvořák L., Horsák M. & Šteffek J. (2007). "Checklist of molluscs (Mollusca) in the Slovak Republic". ''Folia Malacologica'' 15(2): 49-58. Šteffek et al. (2011) confirmed that the snail from Slovakia appears to belong to the genus ''Hauffenia'', based on the morphology of the penial characters. However, molecular phylogeny research based on sequences of mitochondrial Main subunit of cytochrome c oxidase, cytochrome-c oxidase I (COI) genes appears to demon ...

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 ...
