Description:
The remaining bony fish, with a bony skeleton and specific skeletal and gill structures, split into ray-finned fish and lobe-finned fish. The former possessed bony, spiked sorts of fins, while the latter had more fleshy counterparts. The aforementioned lobes connect to the undersides of their bodies, separate from the backbone.Ajouté au bande de temps:
