Order (biology)
In biological classification, the order (Latin: ordo) is
Example: All owls belong to the order Strigiformes
What does and does not belong to each order is determined by a taxonomist, as is whether a particular order should be recognized at all. Often there is no exact agreement, with different taxonomists each taking a different position. There are no hard rules that a taxonomist needs to follow in describing or recognizing an order

De Candolle System
The De Candolle system is a system of plant taxonomy by French (Swiss) botanist Augustin Pyramus de Candolle (1778−1841).

Fishes
Tetrapods
Fish are the gill-bearing aquatic craniate animals that lack limbs with digits. They form a sister group to the tunicates, together forming the olfactores. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Tetrapods emerged within lobe-finned fishes, so cladistically they are fish as well. However, traditionally fish are rendered paraphyletic by excluding the tetrapods (i.e., the amphibians, reptiles, birds and mammals which all descended from within the same ancestry). Because in this manner the term "fish" is defined negatively as a paraphyletic group, it is not considered a formal taxonomic grouping in systematic biology

International Code Of Zoological Nomenclature
The International Code of Zoological Nomenclature (ICZN) is a widely accepted
convention in zoology that rules the formal scientific naming of organisms treated as animals. It is also informally known as the ICZN Code, for its publisher, the International Commission on Zoological Nomenclature (which shares the acronym "ICZN"). The rules principally regulate:
  • Which name must be used in case of name conflicts
  • How scientific literature must cite names
  • ---> Zoological nomenclature is independent of other systems of nomenclature, for example botanical nomenclature. This implies that animals can have the same generic names as plants. The rules and recommendations have one fundamental aim: to provide the maximum universality and continuity in the naming of all animals, except where taxonomic judgment dictates otherwise

    Prefix
    A prefix is an affix which is placed before the stem of a word. Adding it to the beginning of one word changes it into another word. For example, when the prefix un- is added to the word happy, it creates the word unhappy

    Boreoeutheria
    Boreoeutheria (synonymous with Boreotheria) (Greek: βόρειο "north" + ευ "good" + θεριό "beast") is a clade (magnorder) of placental mammals that is composed of the sister taxa Laurasiatheria (most hoofed mammals, most pawed carnivores, and several other groups) and Euarchontoglires (Supraprimates)

    Simiiformes
    The simians (infraorder Simiiformes) are monkeys and apes, cladistically including: the New World monkeys or platyrrhines, and the catarrhine clade consisting of the Old World monkeys and apes (including humans). The simian and tarsier lines of haplorhines diverged about 60 million years ago (during the Cenozoic era). Forty million years ago, simians from Africa colonized South America, giving rise to the New World monkeys

    Catarrhini
    Catarrhini is one of the two subdivisions of the simians, the other being the plathyrrhine (New World monkeys). The Catarrhini contains the Old World monkeys and the apes; the latter of which are in turn further divided into the lesser apes or gibbons and the great apes, consisting of the orangutans, gorillas, chimpanzees, and humans. The Catarrhine are all native to Africa and Asia

    Suffix
    In
    linguistics, a suffix (sometimes termed postfix) is an affix which is placed after the stem of a word. Common examples are case endings, which indicate the grammatical case of nouns or adjectives, and verb endings, which form the conjugation of verbs. Particularly in the study of Semitic languages, suffixes are called afformatives, as they can alter the form of the words. In Indo-European studies, a distinction is made between suffixes and endings (see Proto-Indo-European root). Suffixes can carry grammatical information or lexical information. An inflectional suffix is sometimes called a desinence or a grammatical suffix or ending

    Mineral
    A mineral is a naturally occurring chemical compound, usually of crystalline form and not produced by life processes. A mineral has one specific chemical composition, whereas a rock can be an aggregate of different minerals or mineraloids. The study of minerals is called mineralogy. As of March 2018, there are more than 5,500 known mineral species; 5,312 of these have been approved by the International Mineralogical Association (IMA). Minerals are distinguished by various chemical and physical properties. Differences in chemical composition and crystal structure distinguish the various species, which were determined by the mineral's geological environment when formed. Changes in the temperature, pressure, or bulk composition of a rock mass cause changes in its minerals

    Plant
    Plants are mainly multicellular, predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, plants were treated as one of two kingdoms including all living things that were not animals, and all algae and fungi were treated as plants. However, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants"), a group that includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, mosses and the green algae, but excludes the red and brown algae. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color
