Eodeasensis iuvatquecomaii

From OurFoodChain

As Eodeasensis folufusus populations faced intraspecific competition for space. Lower depths were less crowded due to lower light penetration. This pressure favored individual E. folufusus with taller stems and larger leaves that could absorb more light as a result. This would give rise to an entirely new species.

4 meters tall
Originated in Zone 15(10+ meters deep)

Eodeasensis iuvatquecomaii has several things in common with E. folufusus and E. gelidabulbus. For instance, E. iuvatquecomaii reproduces sexually by dropping seeds or asexually via carpeting and the rooting of broken stems. They have a greater amount of fronds with greater leaf density per stem to absorb sunlight. Due to the lower parts of the water column having less light from sediment upheaval and light penetration, E. iuvatquecomaii's stems have grown to double the length of their ancestors' to reach higher to areas with greater light penetration. The leaves towards the top have become slightly larger to increase the surface area for light absorption, being longer by about 2-3 centimeters. With all of the energy needed for this growth, with the lower leaves absorbing less sunlight, E. iuvatquecomaii has developed the ability to kill their lower leaves when they expend more energy then they gain by degrading chlorophyll within lower leaves. The energy released by the degraded chlorophyll is then reused for growth and maintenance.

With the strong flow in the main river threatening to tear the polyph out of the substrate, E. iuvatquecomaii has developed deeper and more extensive roots to anchor itself. While the upper stems may being torn by the flow, the high abundance of said stems means they can survive and replace lost stems. Meanwhile, the ripped off stem can eventually land somewhere else in the river root. These several different adaptations allow E. iuvatquecomaii to thrive in the main river in Zone 15 living in depths of 10 meters and lower.
