Describing organisms or structures where the two sides are unequal or asymmetrical.
From Greek 'anisos' (unequal) + 'pleura' (side/rib). This anatomical term emerged in biological sciences to describe asymmetrical morphology.
Flatfish like flounder are anisopleural in an extreme way—one of their eyes actually migrates to the same side of their head as they grow, making them completely lopsided!
