Animal - Classification, Taxonomy, Phylogeny: Because the aschelminths have not been studied adequately by modern methods, there is no consensus on their classification. The classification in this article is based on morphological work carried out in the late 1980s and remains to be tested by RNA sequence studies and other comparisons.
Scientists have developed a classification scheme that categorizes all members of the animal kingdom, although there are exceptions to most “rules” governing animal classification (Figure 1). Animals are primarily classified according to morphological and developmental characteristics, such as a body plan. One of the most prominent features ...

Scientific classification (or taxonomy) is the process of grouping animals into different categories. These categories are based on similarities or shared characteristics, such as diet ( carnivore, herbivore etc.), habitat, anatomy, or behavior. Scientists use animal classification to help them study and understand the natural world.
At a very basic level of classification, true animals can be largely divided into three groups based on the type of symmetry of their body plan: radially symmetrical, bilaterally symmetrical, and asymmetrical. Asymmetry is a unique feature of Parazoa (Figure 27.2.2 27.2. 2 ). Only a few animal groups display radial symmetry.
In biology, taxonomic rank is the relative level of a group of organisms (a taxon) in an ancestral or hereditary hierarchy. A common system of biological classification ( taxonomy) consists of species, genus, family, order, class, phylum, kingdom, and domain. While older approaches to taxonomic classification were phenomenological, forming ...
