Perennibranchiate

from Wikipedia, the free encyclopedia

Perennibranchiat is a term from zoology that describes that an organism retains gills ( branchae in Latin ) as respiratory organs during its entire life cycle . This is generally true of several amphibian species such as the spotted newt ( Necturus maculosus ). In some cases only a small fraction of the population is perennibranchial. However, it also happens that the trait is predominant within the population. In the case of the rough-skinned yellow-bellied newt ( Taricha granulosa ) in the cascade chain, 87… 100% of the population are perennibranchiatric.

The opposite term (the organisms lose their gills in the course of their life cycle) is caducibranchiat .
