Infraspecific is a taxonomic rank below species. It is used to classify populations or groups within a species that have distinct characteristics but are not different enough to be considered a separate species. The most common infraspecific ranks are subspecies and variety.

A subspecies is a geographically isolated population of a species that has developed distinct physical characteristics. For example, the Bengal tiger and the Siberian tiger are considered subspecies of Panthera tigris because they are geographically separated and have noticeable differences in size and coat patterns.

A variety is a group of organisms within a species that share common characteristics, but these characteristics are less pronounced than those of a subspecies. Varieties are often used in plant classification. For instance, within the species *Lycopersicon esculentum* (tomato), there are many varieties with different fruit shapes, sizes, and colors, such as the 'Beefsteak' tomato or the 'Cherry' tomato.

The use of infraspecific ranks is a matter of taxonomic judgment and can sometimes be debated among scientists. The decision to classify a group as an infraspecific taxon depends on the degree of divergence and the biological significance of the differences observed. It helps in understanding the evolutionary relationships and biodiversity within a species.
