Classification of animal kingdom

Classification of living organisms Linnaean system of classification Living organisms are classified into groups depending on their structure and characteristics. This system was developed in the eighteenth century by Carl Linnaeus. The classification of species allows the subdivision of living organisms into smaller and more specialised groups. Kingdoms The first division of living things in the classification system is to put them into one of five kingdoms . The five kingdoms are: • animals (all multicellular animals) • plants (all green plants) • fungi (moulds, mushrooms, yeast) • protists (Amoeba, Chlorella and Plasmodium) • prokaryotes (bacteria, blue-green algae) Further divisions Living things can then be ranked according to: • phylum • class • order • family • genus • species Phylum follows Kingdoms and has many different organisms, including three examples below: • Chordata, which have backbones • Arthropod, which have jointed legs and an exoskeleton • Annelids, which are segmented worms Class is an additional sub-division, which for example, results in the Chordata phylum being divided into: • Mammals • Birds • Amphibians • Fish • Reptiles Order follows class and as an example, mammals can be further sub-divide into a variety of different groups such as: • Carnivores • Primates Orders are broken down into families. Here are a few examples of which carnivores can be divided into: • Canidae - dogs • Felidae - cats Genus, the Felidae family can be further sub-divide...

The animal kingdom is separated into nine taxonomic ranks: Life > Domain > Kingdom > Phylum > Class > Order > Family > Genus > Take the lion, for example. Below is the Kingdom: Animalia Phylum: Chordata Class: Mammalia Order: Carnivora Family: Felidae Subfamily: Pantherinae Genus: Panthera Species: Panthera leo Another example is the blue whale, whose animal classification is as follows: Kingdom: Animalia Phylum: Chordata Class: Mammalia Order: Cetacea Family: Balaenopteridae Genus: Balaenoptera Species: Balaenoptera musculus The ranking system is based on a fixed number of levels such as kingdom, family, or genus. The order goes: Animal classification is based on an organisms decent from a common ancestor. Accordingly, the most important traits for classification are those inherited from a common ancestor. An example would be birds and bats, which both can fly, but this characteristic is not used to classify them into a class because they did not inherit this from a common ancestor. Despite their differences, both bats and whales feed their offspring milk, therefor this feature is used to classify them both as mammals. Examples: Whale: Kingdom: Animalia Phylum: Chordata Class: Mammalia Subclass: Eutheria Order: Cetacea Bat: Kingdom: Animalia Phylum: Chordata Class: Mammalia Infraclass: Eutheria Superorder: Laurasiatheria Order: Chiroptera *Note the similarities in bat and whale classification.

• Classification attempts to impose a hierarchy on the complex and dynamic variety of life on Earth by describing how different species group together and how they are related to one another or not. • 'Domain' is the highest rank and 'kingdom' is the second highest rank in the sequence of classification. • Classification groupings have evolved over time in light of new scientific findings. Carl Linnaeus was a Swedish scientist and explorer who specialised in taxonomy and developed his system of classification in the eighteenth century. This is known as 'binomial nomenclature'. The classification of species allows the sorting of living organisms into smaller and more specialised groups. NARRATOR: Manfred, Azumi, Farooq, Gabriela... no wait that's Farooq – or is that Callum. No, that's Callum. Hmm, this is difficult. Well, it doesn't matter. They are fish. They're all fish. That's much more straightforward. There is so much amazing and diverse life on planet Earth that looking at it all can be a big job. So when we study the natural world it can be very useful to group animals together. When we study nature we classify living things into different groups we do this in order to try and make sense of all the incredible bio-diversity on our amazing planet. As we're already here, let's start with fish. I bet all of you could tell me that these animals are fish. You knew that already, right? But why? How did you know? They all look different from each other they have different sh...

• • • • • Animals have different characteristics that call for classification into multiple categories. This animal kingdom classification is important—not just to learn about the different species, but the relationship shared by all. The system was created by a Swedish botanist named Carl Linneaus. It was termed the Linnaeus method or the Linnean method, and it is essentially used to group animals in a hierarchy known as taxa. This method also serves to give species binomial names by fusing the genus and species. This is often known as the binomial nomenclature. The primary method of classifying animals includes domain, kingdom, phylum, class, order, suborder, animal families, genus, and species. Conclusion Animal Kingdom Classification – Animalia Domains The domain is often called the least specific category of classification, and it regroups all of life. There are three main domains: • Bacteria: for cells that don’t contain a nucleus • Archaea: for cells that don’t contain a nucleus and have a cell wall that’s different from bacteria. • Eukarya: for cells that contain a nucleus. The bacteria and archaea domains are quite similar in that they have no nucleus and are both composed of organisms that have only one cell. The organisms also reproduce asexually by dividing into two. The domains are distinguished by the material that makes up their cell walls. The bacterial cell wall is made up of polysaccharide peptidoglycan which the archea doesn’t have. The latter also thriv...

What is Animal Classification? Key Points • Every species is defined based on nine branching categories. • Animals are a kingdom of complex multi-celled organisms that do not produce their own food. This kingdom contains all living and extinct animals. • Every animal family is further divided into small groups known as a genus. Animal kingdom classification is an important system for understanding how all living organisms are related. Based on the Linnaeus method, species are arranged and grouped based on shared characteristics. This system of animal kingdom classification was developed by Swedish botanist This method of giving scientific names to animals is typically rooted in Latin by combining the genus and species. For example, homo sapiens while canis lupus. The more features that a group of animals shares, the more specific that animal classification group is. Every species is defined based on nine branching categories. The primary method of animal classification is: • Domain • Kingdom • Phylum • Class • Order • Suborder • Animal Families • Genus • Species Animal Classification Chart for Water snake (Nerodia Sipedon) ©EreborMountain/Shutterstock.com Animal Classification: The Six Different Animal Kingdoms All living organisms can be placed in one of • Animal – A kingdom of complex multi-celled organisms that do not produce their own food.

Instructor: Reed Hepler Reed Hepler received an M.L.I.S. from IUPUI, with emphases in Digital Curation and Archives Management. He received a Bachelor’s in History from USU, with minors in Religious Studies and Anthropology. He also earned a Certificate in Museum Studies. He has worked in museums, libraries, archives, and historical sites for the past four years. There is only one animal kingdom; this is one of the five kingdoms of life. The other kingdoms in biological taxonomy were created alongside the animal kingdom by Carl Linneaus and his successors in taxonomic biology. Taxonomy is the process of systematically categorizing all animals into specific species. All of these species are organized into specific and broad groups. Kingdoms are the broadest of these taxonomic groups. Examples of organisms contained within the animal kingdom include: • Fish • Coral • Deer • Dogs Organisms that the animal kingdom does not contain include: • Trees • Shrubs • Moss • Bacteria Related to kingdoms and taxonomy is the concept of domain. Domains are at the highest taxonomic level. They are so large that they are often not considered when specifying the taxonomy of a species. The first two domains contain no animals; these are Archaea and Bacteria. Archaea include individual cells, while Bacteria are the most common form of celled organisms, and they are single cells. The third and last domain is Eukarya, or eukaryotic organisms, which includes all animal life. Eukarya consists of ...

Eschrichtius robustus) breaching. In size animals are outdone on land by plants, among whose foliage they may often hide. In contrast, the photosynthetic algae, which feed the open oceans, are usually too small to be seen, but marine animals range to the size of whales. Diversity of form, in contrast to size, only impinges peripherally on human awareness of life and thus is less noticed. Nevertheless, animals represent three-quarters or more of the species on Earth, a diversity that reflects the flexibility in feeding, defense, and reproduction which Animals move in pursuit of food, mates, or refuge from predators, and this movement attracts attention and interest, particularly as it becomes apparent that the behaviour of some creatures is not so very different from
