>the biological reality of those animals
They ALL share a common ancestor at the very first first vertebrate. "Fish" is the subphylum/clade Vertebrata minus the tetrapods.
>Hagfish
Originally, 'Craniata' was used to describe fish to include hagfish, but now it's thought they simply lost their spine through evolution. They are classified as vertebrate species. This is the same way a snake is classified as a tetrapod. All this and you didn't even answer the question because I asked for an animal NOT considered a fish.
