“Relative” means that the classification is made in relation to a broader genus.
Human → animal: human is a species under animal.
Animal → growing body: animal is a narrower kind under growing body.
Thus being a relative species describes a hierarchical relation. A concept can be a species relative to something above while also being genus relative to what lies below.

The Five Predicables: Genus, Species and Hierarchy of Genera
“Relative” means that the classification is made in relation to a broader genus.
Human → animal: human is a species under animal.
Animal → growing body: animal is a narrower kind under growing body.
Thus being a relative species describes a hierarchical relation. A concept can be a species relative to something above while also being genus relative to what lies below.
