Characteristics of Marine Beastmen They are hermaphroditic. Only the upper body has male or female characteristics. Both male and female reproductive organs, along with the digestive tract, are tucked inside a "slit" located near the pubic bone on the ventral side (lower abdomen). They generally resemble merfolk, with gills on their flanks and necks. They have no human legs. From the waist down, they have a tail fin. They are capable of both lung and gill breathing. They can crawl on land, but this causes abrasions on their waist area. Using a wheelchair is the best method for land travel. Their singing has the power to charm and captivate humans who hear it. They go into heat once every few months. The tank is glass-walled on all four sides. They have no legs; below the waist is a complete tail fin. There are no leg bones; the tailbone is highly developed into a large tail fin.
