It is classified between family and class. In biological classification, the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. An immediately higher rank, superorder, is sometimes added directly above order, with suborder directly beneath order. An order can also be defined as a group of ...
In his landmark publications, such as the Systema Naturae, Carl Linnaeus used a ranking scale limited to kingdom, class, order, genus, species, and one rank below species. Today, the nomenclature is regulated by the nomenclature codes. There are seven main taxonomic ranks: kingdom, phylum or division, class, order, family, genus, and species.

Generally accepted members of this infraorder include the living tarsiers, [1] the extinct omomyids, two extinct fossil genera, and two extinct fossil species within the genus Tarsius. [3] As haplorhines , they are more closely related to monkeys and apes than to the strepsirrhine primates, which include lemurs , galagos , and lorises .
Lemuriformes is the sole extant infraorder of primate that falls under the suborder Strepsirrhini.It includes the lemurs of Madagascar, as well as the galagos and lorisids of Africa and Asia, although a popular alternative taxonomy places the lorisoids in their own infraorder, Lorisiformes.
Scincomorpha is an infraorder and clade of lizards including skinks (Scincidae) and their close relatives. These include the living families Cordylidae (girdled lizards), Gerrhosauridae (plated lizards), and Xantusiidae (night lizards), as well as many extinct taxa.
The infraorder Astacidea comprises five extant superfamilies, two of crayfish (Astacoidea and Parastacoidea), one of true lobsters (Nephropoidea), one of reef lobsters (the genus Enoplometopus), and a number of fossil taxa. [6] As of 2009, the group contains 782 recognised species, over 400 of which are in the crayfish family Cambaridae. [6]
The hierarchy of biological classification's eight major taxonomic ranks.Intermediate minor rankings are not shown. In biological classification, [1] a subfamily (Latin: subfamilia, plural subfamiliae) is an auxiliary (intermediate) taxonomic rank, next below family but more inclusive than genus.
