I'm surprised to learn that it is surprising that eels are fish. I mean, they live in water, they have fins, they're generally fish-shaped... What's more surprising is their incredible life cycle and reproductive journey. I'm surprised the author didn't put that in the title.

Oh, but you should not classify living beings according to their habitat and behaviour; classification based on the degree of the phylogenetical relationship is obviously superior and the only truly reasonble one.

I can't tell if you are being facetious or not.

I am; for a more serious take see [0].

    Now, there’s something wrong with saying “whales are phylogenetically just as closely related to bass, herring, and salmon as these three are related to each other.” What’s wrong with the statement is that it’s false. But saying “whales are a kind of fish” isn’t.
