The smallest stratum refers to the most basic, discrete level of classification within a stratified system, often used in statistics, geology, or social sciences. In statistical sampling, a stratum is a subset of a population that shares specific characteristics, and the smallest stratum would be the most narrowly defined group within that population. For example, in a study of a city's residents, the smallest stratum could be defined by a specific demographic like age or income level.
mammals are the smallest group of vertebrates

Species is the most specific group in taxonomy with Kingdom being the broadest group.
