are different scientific names that pertain to the same taxon, for
example two names for the same species. One basic principle of zoological
nomenclature is that the earliest correctly published and available name
(the senior synonym) takes precedence and must be used for the taxon, if
no other restrictions interfere.
Common name:
A common name of an organism (also known as a vernacular name, colloquial
name, trivial name, trivial epithet, country name, or farmer's name) is a
name in general use within a community; it is often contrasted with a scientific
name.
