In biology, dactyly is the arrangement of digit (fingers and toes) on the hands, feet, or sometimes wings of a tetrapod animal. It comes from the Greek word δακτυλος, meaning "finger".

Sometimes the ending "-dactylia" is used. The adjectival forms end with "-dactyl" or "-dactylous".

By number


Pentadactyly is the condition of having five digits on each limb. All land vertebrates are descended from an ancestor with a pentadactyl limb, although many groups of species have lost or transformed some or all of their digits. Despite the individual variations, listed below, the relationship to the original, five-digit 'model' can be traced. This phenomenon featured in the work of Charles Darwin: "What could be more curious than that the hand of man formed for grasping, that of a mole, for digging, the leg of a horse, the paddle of a porpoise and the wing of a bat, should all be constructed on the same pattern and should include similar bones and in the same relative positions?"
