An alternative form of anisodactyl; an animal with unequal or asymmetrical digit arrangement.
From Greek aniso- (unequal) plus dactyle (variant spelling of dactyl, finger/toe). This is a variant spelling used in some older zoological texts.
The spelling anisodactyle versus anisodactyl is like how we spell 'donut' and 'doughnut'—both are correct, but one form eventually becomes preferred, and scientists gradually shifted toward the -il ending for consistency with other zoological terms.
