On page two of the chapter, we said the main division of Teleostomi was between the ray-finned and lobe-finned fishes. To this point in the chapter, every fish has been a ray-fined fish in the superclass Actinopterygii. This page explores the lobe-finned fishes in the superclass Sarcopterygii. It is important to note that every other animal, through chapter 38, is also in the superclass Sarcopterygii. This is another view of the breakdown of Teleostomi:

  • Teleostomi
    • Actinopterygii (previous pages in this chapter)
    • Sarcopterygii
      • Coelacanthimorpha
        • Coelacanthiformes - Coelacanths
      • Dipnotetrapodomorpha
        • Dipnomorpha
          • Ceratodontiformes - Lungfishes
        • Tetrapoda - Four-Limbed Animals (following chapters)
