Philosophers of biology have been contending over the metaphysical status of species for some time now. The dominant view, Species-as-Individuals (SAI), has it that species are concrete particulars composed of organisms. Though popular, the view faces myriad metaphysical difficulties familiar from the study of mereology and ontology. In response, SAI-ists will sometimes claim that they are dealing with a different, biological notion of parthood which evades the difficulties. I examine this response, contending that even if it is coherent, it is unlikely to salvage the view. I articulate a more promising deflationary approach to the metaphysics of species that draws upon recent work on plural reference and predication.
