Having upper and lower jaws that are unequal in size or shape; characterized by anisognathism.
From Greek 'anisos' (unequal) + 'gnathos' (jaw) + '-ous' (adjective suffix). The adjective form describes organisms or individuals with this jaw condition.
Some fish species are naturally anisognathous as an adaptation—an upper jaw that's longer helps them catch prey in specific ways that straight-jawed fish can't manage!
