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.

You should classify living beings according to a system that is helpful to understand and discuss the livings beings in a given context. "Fish" isn't a specific taxon in the standard biological taxonomy, but is rather a description of a specific set of common physical attributes and behaviors that is helpful to differentiate some organisms from other organisms. Regardless of official taxonomy, for 99.99% of people it's helpful to describe eels as fish.
