Coralliophilidae and Muricidae are side by each in Vaught's taxonomic
work - the first two families in the superfamily Muricoidea (order
Neogastropoda, subclass Prosobranchia, class Gastropoda, Phylum
Mollusca, Kingdom Animalea (ending??), which are all eukaryotes), which
also includes Buccinidae, Columbellidae, Nassariidae, Melongenidae,
Fasciolariidae, Volutidae, Harpidae, Vasidae, Olividae, Marginellidae,
Mitridae, Volutomitridae and Costellariidae - it's a real Super Superfamily!!!
