How are organisms classified in the animal kingdom?
All organisms are categorized into kingdoms. There are kingdoms associated with plants, fungi, animals, bacteria, and protists. Animals belong to the Animalia Kingdom. From there, animals are divided based on their features and characteristics. Animals are classified as two main groups in the animal kingdom: vertebrates and invertebrates.
How are animals classified according to their features?
Here, animals are grouped by their main features. Animals usually fall into one of five different phylum which are Cnidaria (invertebrates), Chordata (vertebrates), Arthropods, Molluscs and Echinoderms. The phylum group is then divided into even smaller groups, known as classes.
How are vertebrates divided into different classes of animals?
The phylum group is then divided into even smaller groups, known as classes. The Chordata (vertebrates) phylum splits up into Mammalia (Mammals), Actinopterygii (Bony Fish), Chondrichthyes (Cartilaginous Fish) , Aves (Birds), Amphibia (Amphibians) and Reptilia (Reptiles). Each class is divided into small groups again, known as orders.
What different groups of animals are called?

Whenever animals gather in groups, they are formally called: Apes: a shrewdness. Badgers: a cete. Bats: a colony or a camp. Bears: a sloth or a sleuth. Bees: a swarm.
How are living things classified into groups?
All living organisms are classified into groups based on very basic, shared characteristics . Organisms within each group are then further divided into smaller groups. These smaller groups are based on more detailed similarities within each larger group. This grouping system makes it easier for scientists to study certain groups of organisms.
How do people classify animals?
Classifying an Animal Based on its Scientific Name Start with an animal’s scientific name. The final two taxonomic ranks, genus and species, which are are the most specific of all the ranks, are used for an animal’s scientific name. Use the animal’s scientific name as a starting point for research.

Animals are primarily classified according to morphological and developmental characteristics, such as a body plan. One of the most prominent features of the body plan of true animals is that they are morphologically symmetrical. This means that their distribution of body parts is balanced along an axis.

Which is the largest group in the animal kingdom?
The scientific classification system is divided into seven major groups, (1) kingdom, (2) phylum or division, (3) class, (4) order, (5) family, (6) genus, and (7) species. The kingdom is the largest group and a species is the smallest. In the Animal Kingdom, the term phylum is used, and it is the second largest group.
What are two groups of animals that do not have a backbone?
Animals can be broadly divided into two groups: invertebrates and vertebrates. Invertebrates are animals that do not have a backbone. They make up nearly 97 per cent of all animal species.
