It’s all a matter of which fish we evolved from and what solution evolution came up with, in the development from that water-breathing creature to air breathers. It could have produced separate air and foodways, as it did for whales and dolphins. But the blind idiot has no foresight and it can’t get there from here any more.
Dolphins and whales have the same fish ancestors we do; they’re former terrestrial mammals who returned to the sea and share the same common ancestors of all mammals.
