What does class mean in science?
Class is a taxonomic rank (a taxon) consisting of organisms that share a common attribute; it is further divided into one or more orders. In the biological classification of organisms, a class is a major taxonomic rank below the phylum (or division) and above the order.

The level of differentiation we are going to examine in this program is the broad taxonomic classification “class.” The phylum chordata (animals with backbones) is divided into five common classes: fish, amphibians, reptiles, mammals and birds.
Are order and class the same?
The order ranks below the class and above the family in the taxonomic hierarchy. The groups in an order have more in common with each other than they do with other members of the same class.
What’s the difference between class and phylum?
Phylum is at a higher rank than class. Number of species in a phylum is much higher than that in a class. Class is more specific than phylum. The probability of describing a new phylum is lower than class.
