Relating to, having, or moving toward a tail; of or pertaining to tail-like structures or movement in a caudal direction.
From Latin cauda (tail) plus the adjectival/noun-forming suffix -atory (denoting relation, tendency, or function), creating an adjective describing tail-related qualities or functions.
This is another example of Latin suffixes getting piled onto each other—'-atory' usually describes what something does or tends toward, so 'caudatory' would suggest something that moves or tends tailward, which is wonderfully specific.
