Adults of the invertebrate species in the Phylum Chordata look and behave exactly like fish, but have completely flexible bodies because they lack backbones

 Bony fishes as a group are more morphologically diverse than the cartilaginous fishes as a group. 

Gas exchange in many sharks depends on 

Vertical zonation patterns in the distribution of prominent space-occupying species is due to differences among species in their ability to tolerate air exposure at low tide
