If you look at the Wikipedia pages for many of these animals, they’ll use terms like, “true eel,” “true goat,” and “true cobra.” I guess that’s how they generally handle animals that share common names despite not technically being in the correct family or whatever.
If you really need to be specific the scientific name or phylogenetic genus is there if you need to avoid the popular morphological name. Trying to fit the two together will always cause problems. For an example, see “fish.”
