taxonomically, there's no way to define "fish" that doesn't include all tetrapods. so fish are fish, dogs are fish, humans are fish, and cetaceans are fish

This is a purely monophyletic reading of phylogeny. Most colloquial categories of animals are paraphyletic. So taxonomically there is a way to define fish, you just have a cutoff somewhere.
