There are 9 classes of animals. Coelenterates, Echinoderms, Crustacea, Arachnids, Fish, Amphibia, Reptiles, Birds & Mammals.
Answer
Animals are heterotrophic, multicellular, anisogamous, nucleated organisms that lack cell walls. The animal kingdom (Kingdom Animalia) may contain 30 000 000 species or more. The kingdom is divided into about 30 phyla (singular- phylum). Each phylum is divided into classes, each class into cohorts (if applicable), each cohort into orders, each order into families, each family into tribes (if applicable), each tribe into genera (singular- genus) and each genus into species. There are also subdivisions (if applicable) such as superorder, suborder, infraorder, superfamily etc.....
It is hoped that the final classification of animals shall reflect their evolutionary history. In other words each taxon (eg phylum, class, family etc) should be a monophyletic group. This means that all the entities within a group should have a single common ancestor and thus be true descendants of that one species and thus be true representatives of the group. Below is an overview of some phyla.
Phylum Porifera (sponges - usually considered the most primitive of all truly animalian phyla - loose aggregations of cells comprise a sponge with silica spicules embedded).
Phylum Cnidaria (jellyfish, corals, cube jellies)
Phylum Platyhelminthes (flatworms, tapeworms)
Phylum Rotifera (rotifers)
Phylum Nematoda (nematodes - worms such as roundworms)
Phylum Kinorhyncha (no common name technically - sometimes called 'mud dragons')
Phylum Tardigrada (related to arthropods)
Phylum Onychophora (related to arthropods)
Phylum Arthropoda (invertebrates with jointed legs and an exoskeleton - classes often defined according to number of legs eg Class Insecta have ecreatures with 6 legs while Class Arachnida have creatures with 8 legs - classes further divided into orders - insects divided into Orders Coleoptera, Hemiptera, Hymenoptera, Lepidoptera, Isoptera, Diptera and many others - arachnids divided into fewer orders such as Orders Araneae, Scorpiones and Solifugae).
Phylum Annelida (segmented worms such as earthworms (Class Oligochaeta) and leeches (Class Hirudinea) - the classification is unsettled as to the position of polychaetes in relation to other annelids)
Phylum Echinodermata (starfish, sea cucumbers, sea urchins, brittle stars)
Phylum Hemichordata (acorn worms)
Phylum Priapulida
Phylum Sipuncula
Phylum Brachiopoda
Phylum Echiura
Phylum Ectoprocta
Phylum Entoprocta
Phylum Chaetognatha
Phylum Loricifera
Phylum Micrognathozoa
Phylum Cycliophora (3 species so far discovered such as Symbion pandora)
Phylum Chordata (this phylum contains both invertebrates and vertebrates but all possess a notochord at some stage)
I will cover the chordates in more detail below:
Class Urochordata (sometimes considered a phylum - tunicates/sea squirts - sedentary organisms with free-swimming larvae)
Class Cephalochordata (lancelets, which give clues as to the origin of fishes)
Classes Myxini and Cephalaspidimorphi (lampreys and hagfish - both jawless, but true vertebrates)
Class Chondrichthyes (sharks and rays - possess true jaws and a cartilagenous skeleton)
Classes Actinopterygii and Sarcopterygii (bony fish - the Sarcopterygii give clues as to the origin of lunged and legged creatures such ie the amphibians)
Class Amphibia (frogs, toads, salamanders, caecilians)
Class Reptilia (snakes, crocodiles, lizards, tortoises, turtles)
Class Dinosauria (extinct, terrestrial reptile-like comprised of theropods, ornithopods, ceratopsians, stegosaurs, sauropods, prosauropods and ankylosaurs)
Class Aves (evolved from the Dinosauria - feathered oviparous, flying vertebrates)
Class Mammalia (evolved from predinosaurian reptiles called mammal-like reptiles - suckling, hair-possessing animals with differentiated teeth).

Describe the structure of the modern classification system?
The modern classification system uses homologies to group species into larger and more general categories. A speciesis a group of organisms that is capable of breeding with each other. Species with many of the similar characteristics are grouped in the same genus (plural: genera). Similar genera are grouped in the same family. A group of related families is called an order. A group of related orders is called a class. A phylum (plural: phyla) is a group of related classes. A kingdom is a group made up of similar phyla.The order from most specific to most general is:SpeciesGenusFamilyOrderClassPhylumKingdom
What are phylums divided into?
The term phylum is one of seven major categories that are used to classify organisms. In order of broad to specific, these seven categories are: Kingdom, Phylum, Class, Order, Family, Genus, and Species. Carolus Linnaeus developed this system of classification in the 18th century. answered by a 10 year old
What is the largest most general type of group in a classification system?
It is Domain.
Linnaeus based most of his classification system on?
In plants he used no of stamens , in general classification was based on similar characters .
What system was used before the Dewey Decimal system?
Before the Dewey Decimal system, libraries used classification systems such as the fixed location system, the Cutter Expansive Classification, and the Brown Classification system. These systems were used to organize library materials based on specific categories and sequences.
What are the 7 classification categories from general to most specific?

What is the hierarchical system of classification used in biology?
The hierarchical system of classification in biology is called taxonomy. It starts with broad categories like domain and goes down to specific categories like species. The main levels are domain, kingdom, phylum, class, order, family, genus, and species.

How organisms are organized?

What are the library of congress classification system?
The Library of Congress Classification System (LCC) organizes materials into 21 branches of knowledge. These basic categories (labeled A - Z, with the exceptions of I, O, W, X and Y) are then divided into more specific subclasses by incorporating additional letters.
What is difference in purpose between taxonomic key and classification system?
Taxonomy is the science of classification, or a given organism's specific scientific classification. Classification is simply the act of putting things in different categories, though it may be used as a noun (e.g. 'an animal's classifcation') in which case it is basically the same as taxonomy.
What do meant by classification and codification?
Codification is a system of classifying items by their groups. The classification of items is classifying these items into categories of groups.
What is the Dewey decimal system classification?
The answer is: a system used by libraries to classify nonfictional publications into subject categories
What is the Henry system of classification and how does it work?
The Henry system of classification is a system used to classify fingerprints based on patterns within the ridges. It categorizes prints into three main groups: loops, whorls, and arches. By analyzing the specific patterns of these categories, fingerprints can be further distinguished and matched for identification purposes.
What is the general and therefore the largest classification group called for the body?
Organism is the general and therefore largest classification group for the body. The next smallest classification is the organ system.
