All Species

Species is the atlas widest category by count and the one this structure wave laid a sub category tree under first: individual organisms, one species per entry, drawn from across the tree of life rather than one kingdom. See the species sub categories for how the tree divides, by taxonomic class for animals, by division for plants, and by kingdom for fungi and protists.
