Which is the largest phylum of Kingdom Animalia?
Arthropod, any member of the phylum Arthropoda, the largest phylum in the animal kingdom, which includes such familiar forms as lobsters, crabs, spiders, mites, insects, centipedes, and millipedes. About 84 percent of all known species of animals are members of this phylum.
What is the largest phylum of invertebrates?
The largest animal phylum is also included within invertebrates: the Arthropoda, including insects, spiders, crabs, and their kin. All these organisms have a body divided into repeating segments, typically with paired appendages.
What is the smallest group into which an organism can be classified?
The smallest taxon is the species, which we have already defined as a group of organisms that can breed with each other and produce fertile offspring. A species is made up of the most closely related organisms. For example, humans belong to the human species, Homo sapiens.
Are insects the largest group of animals?
Insects also probably have the largest biomass of the terrestrial animals. The largest numbers of described species in the U.S. fall into four insect Orders: Coleoptera (beetles) at 23,700, Diptera (flies) at 19,600, Hymenoptera (ants, bees, wasps) at 17,500, and Lepidoptera (moths and butterflies) at 11,500.
What are the 7 classifications of animals?
There are seven major levels of classification: Kingdom, Phylum, Class, Order, Family, Genus, and Species. The two main kingdoms we think about are plants and animals. Scientists also list four other kingdoms including bacteria, archaebacteria, fungi, and protozoa.
What two major phyla are animals classified?

What are the 7 Phylums?

What are examples of phylum?
Example Phylum: Chordata. You are a member of a phylum Chordata. It contains all of the vertebrate animals (fish, birds, reptiles, amphibians, and mammals), as well as a couple of invertebrate ones.
What are the 7 taxa of classification in order from largest to smallest?
Taxonomy is based on a hierarchy of classification; the lower you go in the hierarchy, the more closely related the living things are. These groups, from largest to smallest are Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species. There are 3 domains: Archaea, Bacteria, and Eukarya.
What are the 8 levels of the modern classification system?

Which is the correct order of classification from largest group to smallest?

What is the largest group in the animal kingdom?
Phylum Arthropoda is the largest of all the phyla of animals according to the number of species in this particular group. Arthropods are characterized as animals with jointed legs and a hard external skeleton made of chitin. Animals in this group include spiders, insects and crustaceans.
Why Arthropoda is the largest phylum?
Answer: Phylum Arthropoda has almost a million species described to date. It accounts for 80% of known animal species. So phylum Arthropoda is the largest phylum in the animal kingdom.
Which is the smallest phylum in animal kingdom?
