Form (zoology)

In zoology, form (Latin: forma) is a strictly informal term that is sometimes used to describe organisms. Under the International Code of Zoological Nomenclature the term has no standing (it is not accepted). In other words, although form names are Latin, and are sometimes wrongly appended to a binomial name, in a zoological context, forms do not have any taxonomic significance; such names are unavailable, do not have authors or dates, and do not compete for homonymy.
