Series (biology)

from Wikipedia, the free encyclopedia

In biology, a series is understood to be a level of the classical system inserted between conventional ranks such as class and superclass , which is occasionally introduced when no other ranks are available. An example are the terrestrial vertebrates (Tetrapoda), a taxon that is pushed between the superclass of the jaws (Gnathostomata) and the classes of the amphibians (Amphibia), reptiles (Reptilia), birds (Aves) and mammals (Mammalia), around the latter groups to part from the fish .
