Yup so taking Genus only there are 21 Planatary bios ?Odyssey added 90 unique species, which have their own models, and variants are just different colours on the same model. It goes like this: Genus -> Species -> Variant. For example, Osseus -> Osseus Discus -> Osseus Discus - Red.
So 1 Osseus , which has 6 species then multiple variants . 1 bacterium , 1 tussock etc .
