which includes dogs and cats. Phylum: The group of classes with similar distinctive characteristics constitute a phylum. The classes Pisces, Amphibia, Reptilia, Aves and Mammalia constitute the next higher category, phylum Chordata. These classes share some common features like presence of a notochord and a dorsal tubular nerve cord hence included in the phylum Chordata.

The scientific name ensures that each organism has only one name. Binomial nomenclature (L. Bi -two; Nomen -Name) Biologists follow universally accepted principles to provide scientific names to known organisms.
Each name has two components, a generic name and a specific epithet. This system of naming the organism is called Binomial Nomenclature which was popularised by Carolus Linnaeus and practised by biologists all over the world.
