GNSS are separated into 23 species following the letters of the alphabet, with only J, L, and T missing. Many species are further separated into subspecies. For example, a species D GNSS can be DA subspecies, DB subspecies, or no subspecies (Pure D). This guide will cover examples and common traits of each species starting with the rarest and ending with the most common.

While the species trait is important, each GNSS is a 1/1 generative work of art with many other traits. There are several other quirks in the collection, including "drip", an unsortable trait that I have attempted to compile in the Driplist Gallery
