The Linnaean Taxonomic Hierarchy
Captions available
The idea
The Linnaean system classifies organisms into nested categories: domain, kingdom, phylum, class, order, family, genus, and species.
In practice
A dog's classification moves from the broad domain Eukarya through kingdom, phylum, and class to the genus Canis and species lupus.
Where people slip
Each level nests inside the one above it — a phylum places an organism within one domain and kingdom, not alongside them.
