Reference of classification of animals
Answers
Answer:
This system of animal kingdom classification was developed by Swedish botanist Carolus (Carl) Linnaeus in the 1700's. The Linnaeus Method, also known as Linnaean Taxonomy, creates a hierarchy of groupings called taxa, as well as binomial nomenclature that gives each animal species a two-word scientific name.
Answer:
This system of animal kingdom classification was developed by Swedish botanist Carolus (Carl) Linnaeus in the 1700's. The Linnaeus Method, also known as Linnaean Taxonomy, creates a hierarchy of groupings called taxa, as well as binomial nomenclature that gives each animal species a two-word scientific name.
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
All living organisms can be placed in one of six different animal kingdom classification. The characteristics of each animal kingdom are:
Animal – A kingdom of complex multi-celled organisms that do not produce their own food. This kingdom contains all living and extinct animals. Examples include elephants, whales, and humans.
Plants – Complex and multi cellular autotrophic organisms, meaning they produce their own food through photosynthesis. Examples include trees, flowers, and grass.
Fungi – Multi-celled organisms that do not produce their own food, unlike plants. Examples include molds, mushrooms, and yeast.
Protista – Single celled organisms with more complexity than either eubacteria or archaebacteria. Examples include algae and amoebas
Eubacteria – Single celled organisms found in everything from yogurt to your intestines. This kingdom contains all bacteria in the world not considered archaebacteria.
Archaebacteria – The oldest known living organisms. Single-celled and found in hostile and extremely hot areas like thermal vents or hot springs
Animal Phylums Explained
After animal kingdom, animal species usually fall into one of seven different phylum, or phyla:
Porifera – Marine animals more commonly known as sponges and found in every ocean on earth.
Cnidaria – Mostly marine animals that include over 11,000 species. Examples include coral, jellyfish, and anemones
Platyhelminthes – Typically parasitic flatworms. Lacking in any respiratory or circulatory systems, oxygen pass through their bodies instead in a process known as diffusion. Examples include tapeworms and flukes.
Annelida – More complex than Platyhelminthes, these are segmented and symmetrical worms containing a nervous system, respiratory system, and sense organs. Examples include the common earthworm and leeches.
Mollusca – The second largest phylum by species count, and the largest marine phylum. Invertebrates with soft unsegmented bodies. It is estimated almost a quarter of marine life fall in this category. Examples include clams, mussels, and snails
Arthropoda – Invertebrate animals with an exoskeleton and segmented bodies. Contains insects, crustaceans, and arachnids. This is the largest phylum by species count. Examples include scorpions, butterflies, and shrimp
Chordata – Vertebrates. Animals that develop a notochord, a cartilaginous skeletal rod that supports the body in embryo and can often become a spine. Most animals we are familiar with, including dogs, horses, birds, and humans fall in to this category.
Animal Classes
The phylum group is then divided into even smaller groups, known as animal classes. The Chordata phylum splits in to these seven animal classes:
- Agnatha (jaw-less fish)
- Chrondrichtyes (cartilaginous fish)
- Osteichthyes (bony fish)
- Amphibia (amphibians)
- Reptilia (reptiles)
- Aves (birds)
- Mammalia (mammals)
Different Animal Orders
Each class is divided into small groups again, known as orders. There is no universally accepted breakdown for the class Mammalia. Some outline as many as 26 different orders for the class mammalia.
Animal Families
In every order, there are different animal families which all have very similar features. The Carnivora order breaks into animal families that include Felidae (Cats), Canidae (Dogs), Ursidae (Bears), and Mustelidae (Weasels).
Animal Genus Types
Every animal family is further divided into small groups known as genus. Each genus contains animals that have very similar features and are closely related. For example, the Felidae (Cat) family contains genus including Felis (small Cats and domestic Cats), Panthera (Tigers, Leopards, Jaguars and Lions) and Puma (Panthers and Cougars).
Animal Species Names
Each individual species within the genus is named after its individual features and characteristics. The names of animals are based in Latin and consist of two words. The first word in the name of an animal will be the genus, and the second name indicates the specific species. This method of organizing scientific names of animal species was developed by Carl Linnaeus in the 1700’s. As an example, a dolphin species name is Delphinus Delphis. A red fox is Vulpes vulpes.
