A species in the game Stick Ranger is an organized category of enemies. Each species contains a set of enemies that have similar appearances or movements, and all enemies belong to exactly one species. This makes it easy to distinguish similar types of enemies from each other, thus it is used as part of enemies' names. Enemies of the same species need not necessarily be found in the same area.
