Myth of Seahairs

There is neither ground nor soil in this habitat covered with a clear liquid resembling water. The liquid's bottom isn't visible, because there is none. The liquid's surface separates below and above, and both are endless.  

During hours of the day, there is no light source other than bioluminescent plants. At night, the moon is the only light source, and seahairs absorb the moonlight for their bioluminescence to be active during the day. 

Seahairs are depicted as gatherings of hair, almost looking like untied ponytails. Roots and foliage are visibly different only through the daytime. The roots, which are under the water start to have bioluminescent qualities until there is moonlight again. The foliage floats on the liquid's surface, and as they slowly grow out, the roots grow out too in the opposite direction. 

Under the moonlight, the entire plant is one color, and they variegate in shades of brown and gray. Rarely, a white variety is produced, and according to the myth, a milk-flower grows out of it, chemically balancing the clear liquid as it dies and dissolves. 

Seahairs are primitive in their way of reproduction, they multiply and divide, then gather with help of the liquid's flow. Hours of the day is when plants get their nutrition. By sensing the bioluminescent roots, they feed off of the light. They can completely sustain this ecology without needing any additional source.
