Juga Orickensis
''Juga'' is a genus of freshwater snails with a gill and an operculum, aquatic gastropod mollusks in the family Semisulcospiridae. These snails are native to the rivers of the northwestern United States and adjacent British Columbia. Several species are endemic to isolated large springs in the American Great Basin.Strong, E. E., & Whelan, N. V. (2019). Assessing the diversity of western North American Juga (Semisulcospiridae, Gastropoda). Molecular Phylogenetics and Evolution, 136, 87-103. The most abundant and widespread species, ''Juga plicifera'', attains a height of up to 35 mm. It is sculpted with fine spiral ridges and variably developed ribs that frequently disappear in parts of the shell made as the animal matures. Species The following species and subspecies are recognized: Subgenus ''Juga'' s.s. * ''Juga hemphilli'' (J. Henderson, 1935) ** ''Juga hemphilli dallesensis'' (J. Henderson, 1935) ** ''Juga hemphilli maupinensis'' (J. Henderson, 1935) * ''Juga pl ...

Animal
Animals are multicellular, eukaryotic organisms in the Kingdom (biology), biological kingdom Animalia. With few exceptions, animals Heterotroph, consume organic material, Cellular respiration#Aerobic respiration, breathe oxygen, are Motility, able to move, can Sexual reproduction, reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of Cell (biology), cells, the blastula, during Embryogenesis, embryonic development. Over 1.5 million Extant taxon, living animal species have been Species description, described—of which around 1 million are Insecta, insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have Ecology, 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 Symmetry in biology#Bilate ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ...
