In biological taxonomy, the next smallest classification group after Order is Family. This is part of the classification system that ranges from broad categories to more specific ones, which include Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species.
In the biological classification system, the next smallest group after Order is Family. This refers to the hierarchy of taxonomic ranks in biology, where organisms are classified from broad categories to more specific ones. The sequence of ranks from broad to specific is: Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species. Each rank gets more specific as you go down the list. So, if you're looking at the rank just beneath Order, it would be Family. For instance, in the Order Carnivora (carnivores) one of the Families is Felidae (cats).
