The smallest taxon in biological classification is species. It consists of individuals that are capable of interbreeding and producing fertile offspring.
Species within the class Cephalaspidomorphi, which includes the lampreys, comprise the smallest number of species among vertebrates, with around 38 recognized species.
The highest taxon that contains all others listed is the kingdom.
The species is the smallest and most significant taxon in biological classification. It refers to a group of organisms that can interbreed and produce fertile offspring. Each species is unique and plays a distinct role in ecosystems.
Kingdom is the real taxon that has a clear biological identity as it contains all the organisms.
The order of the Monotremata contains the fewest species, with only five extant species. These species include the platypus and four species of echidnas.
Starting with the Domain, the fifth taxon group is the Order. The taxon groups in order from largest to smallest are Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species.
taxon
The Order is the third smallest taxon in the Linnaean system, ranking below Phylum and Class.
The smallest group into which an organism is classified is species. Species is the most specific level of classification in the Linnaean system of taxonomy and represents a group of organisms that can interbreed and produce fertile offspring.
Species.
The taxon that includes only organisms that can successfully interbreed is called a species. Members of the same species are able to mate and produce viable, fertile offspring.
