About Animals

Animals by Scientific Class Names

The scientific names of animals are named and classified using the binomial nomenclature system of biology. This system is based on a series of hierarchical structures, from the broadest to the most specific, including kingdom, phylum, class, order, family, genus, and species. The following is the general structure of the scientific names of animals:

ClassnameExample
KingdomAnimaliaHomo sapiens、Canis lupus familiaris
PhylumChordataBalaenoptera musculus、Aves
ClassMammaliaPanthera tigris、whale
OrderPrimatesGorilla gorilla、Macaca mulatta
FamilyHominidaeHomo sapiens、Gorilla
GenusHomoHomo sapiens、Homo neanderthalensis
SpeciesHomo sapiensModern humans only

This classification method helps biologists clearly understand and study the relationship between species, and promotes various biological studies.
