common name: translation
the vernacular name of a species, varying from place to place, by language and over time. Scientific names, in contrast, are in Latin or latinised Greek world-wide and are subject to rules of usage that cannot apply to common names. Some common names of rare or deepsea species are artificial "book names" as these species are never seen by the general public. They are coined simply to provide a consistent format in books where common names are used or to provide a means of communication with people unfamiliar or uncomfortable with Latin names
