A taxonomic group of birds characterized by having toes of unequal length, where three toes point forward and one points backward.
From Greek 'anisos' (unequal) + 'daktylos' (finger or toe) + Latin plural '-i'. This zoological term was used to classify birds based on their toe structure differences.
This scientific name reveals how biologists literally use words to describe body parts: 'aniso-' means unequal and 'dactyli' means fingers/toes, so it's basically 'birds with unequal-length toes'—taxonomy is just careful description!
