जीव बिज्ञान के वर्गीकरण में, रैंक जीव सभ के समूहन के आपसी तर-ऊपर क्रम की हिसाब से बँटवारा क लेवल या स्तर बाटे।
जीव बिज्ञान में प्राणी सभ के बर्गीकरण खातिर केतना प्रकार के टैक्सोनौमिक रैंक सभ प्रचलन में बा ई संख्या कौनों निश्चित संख्या नइखे। काहें से कि, अगर जरूरत पड़े, टैक्सोनॉमिस्ट लोग नया रैंक के भी गढ़ लेला, हालाँकि, नया रैंक के नाँव रखे खातिर जरूर कुछ सीमा तय कइल गइल बा जेवन कि नामकरण कोड (nomenclature code) के अनुसार होखे के चाहीं।
एही कारण नीचे दिहल रैंक सभ एक ठो सभके समाहित करत बिधि से बनावल गइल बाटे जे रैंक सभ के आपसी तरऊपरिया स्थिति बतावे भर खातिर दिहल जात बाटे (नोट देखीं):[2]
These are movable ranks, most often inserted between the वर्ग and the लेजियन or कोहॉर्ट. Nevertheless, their positioning in the zoological hierarchy may be subject to wide variation. For examples, see the Benton classification of vertebrates[मुर्दा कड़ी] (2005).
In zoological classification, the कोहॉर्ट and its associated group of ranks are inserted between the वर्ग group and the ordinal group. The कोहॉर्ट has also been used between इन्फ्राorder and family in saurischian dinosaurs (Benton[मुर्दा कड़ी] 2005). In botanical classification, the कोहॉर्ट group has sometimes been inserted between the बिभाग (phylum) group and the वर्ग group: see Willis & McElwain (2002: 100–101), or has sometimes been used at the rank of order, and is now considered to be an obsolete name for order: See International Code of Nomenclature for algae, fungi, and plants, Melbourne Code 2012, Article 17.2.
The supra-ordinal sequence gigaorder-megaorder-capaxorder-hyperorder (and the microorder, in roughly the position most often assigned to the parvorder) has been employed in turtles at least (Gaffney & Meylan 1988), while the parallel sequence magnorder-grandorder-mirorder figures in recently influential classifications of mammals. It is unclear from the sources how these two sequences are to be coordinated (or interwoven) within a unitary zoological hierarchy of ranks. Previously, Novacek (1986) and McKenna-Bell (1997) had inserted mirorders and grandorders between the order and सुपरorder, but Benton (2005) now positions both of these ranks above the सुपरorder.
Additionally, the terms biovar, morphovar and serovar designate bacterial strains (genetic variants) that are physiologically or biochemically distinctive. These are not taxonomic ranks, but are groupings of various sorts which may define a bacterial subप्रजाति.
