| Many small and some large tetrapods with no obvious arboreal features can get into trees. |
| The limbs and appendicular musculature of tetrapods are a further elaboration of the non-axial musculature. |
| In other tetrapods, haemal arches do not begin for several vertebrae posterior to the sacrum. |
| The labyrinthodonts, parareptiles and theromorphs were among the most ancient tetrapods. |
| The fins are very flexible and potentially useful for supporting the body on land, as in lungfish and tetrapods. |
| Evolutionists sought the ancestry of the tetrapods among the lobe-finned fishes. |
