The Maruna are a serpent like species that live in shallow oceans. They are vicious hunters catching their prey and trapping them with their tentacles. Their chests are covered in scales and smooth skin, on their back they have 1 fin to aid in steering in the water. 
Their tentacles are also very helpful during mating to hold their partner exactly where they want. Their genitals consist of smooth scales wrapped in a very large soft skin.
