As it bears no resemblance whatsoever to a hippopotamus, the peculiar common name of Paracanthus hepatus probably derives from a long-standing mispronunciation of its scientific name.
Blue Hippo Tangs, Paracanthurus hepatus, are found dispersed throughout the waters of the Indo Pacific region. Its common name "Hippo" is a reference to the similarity in sound between the scientific name "Hepatus" and the animal "Hippopatamus."
