One unusual variant of gargoyle dwells not amid buildings and ruins but under the waves of the sea. These creatures are known as kapoacinths—they have the same basic statistics as normal gargoyles, save that they have the aquatic subtype and their wings grant them a swim speed of 60 feet (but are useless for actual flight).
Kapoacinths dwell in shallow, coastal regions where they can shamble up from the surf to prey on those that reside there. They are more likely to form wings, as kapoacinths prefer group living to a solitary lifestyle.
