Not sure how plastics would be integrated into organisms' lives unless they were used as temporary habitats like a hermit crab would use objects for shells. In evolutionary terms, I don't think integration would happen because plastic decomposes over a few hundred years and adaptations generally arise over millions. Additionally, plastic as a refined material doesn't really make much sense as being integrated into fish bones/organic forms because none are able to synthesize it. Actually, cartilage seems like it's already able to provide the few benefits, like flexibility and compression-resistance, that plastic could in organic forms.
