Animal encompasses different species-natures such as human, horse and sheep. It is therefore not a real species for that whole collection: the individuals do not all agree in one species-essence.
However, animal is a relative species under the broader growing body, which also includes vegetation in the classical hierarchy.
Being a relative species does not therefore automatically make a concept a real species.
