The category used to classify organisms based on similar characteristics ranking below phylum and above order is called “class.” In biological taxonomy, the class is a taxonomic rank or category that groups together organisms with shared characteristics. It is one of the hierarchical levels used to organize and classify the diversity of life on Earth.

The classification system is based on the principle of grouping organisms based on their evolutionary relationships and shared traits. The classification system allows scientists to organize and study the vast array of different organisms, making it easier to understand and communicate about them.

In this hierarchical system, the highest category is the domain, followed by kingdom, phylum, class, order, family, genus, and species. Each level is characterized by increasingly specific characteristics and relationships among the organisms within it.

The class level focuses on organisms that share more specific traits than those within the same phylum but are not closely related enough to be grouped into the same order. Organisms within the same class share certain common characteristics and evolutionary history, which allows scientists to study them together.

For example, in the animal kingdom, the phylum Chordata is divided into several classes, such as mammals (Class Mammalia), birds (Class Aves), reptiles (Class Reptilia), amphibians (Class Amphibia), and so on. Each class includes organisms that share specific characteristics such as skeletal structure, reproductive methods, or other traits.

Classifying organisms into classes helps in organizing and understanding their diversity, as well as facilitating further research and study. It allows scientists to make predictions about an organism’s behavior, anatomy, and physiology based on its classification, and helps in identifying new species and discovering evolutionary relationships among different groups of organisms.
