A species with green fins established a colony on the gas giant called Yorn Skot. These humanoid beings possessed skin ranging from a vibrant green to an olive hue, marked by darker green mottled patterns on their heads and arms. Distinctive small green fins adorned the posterior aspects of their forearms and calves. While some members of the species exhibited cranial hair, they were generally hairless. Both sexes displayed diminutive ears and gill-like formations along the sides of their necks, and females possessed breasts. Their eyes were characterized by a circular shape and a sizable round pupil, and their teeth were notably pointed.
Clode Rhoden, Madam Rhoden, and Buck belonged to this particular species.
