Notes 

• The Gill Man is a number of aquatic-based humanoids that dwell off the coast of the ocean and in the brackish rivers in the known world. Their physiology including gills, webbed appendages, and naturally toughened flesh allows them to dwell beneath the surface with little need to appear, however, in addition to gills, these creatures possess a set of air sacs that allow it to dwell for temporary periods on land without suffocating.
• While not necessarily malicious, The Gill Man along with the rest of his kind are territorial and will defend regions that they deem theirs. Any mutual attraction that these creatures have to beautiful human women (and possibly men) is still not understood by scientists. The Gill Man does have an ability to project almost supernatural empathy to create an attraction.
• Has an environmental weakness to drying out. This does require a Gill Man to regularly become submerged, preferring salt or brackish level water over pure fresh water, but any liquid will ultimately suffice in keeping its skin and sensitive organs properly moist.
