Transparent Gildron

Splitting from its ancestor, the transparent gildron has simplified its body plan even more and has, as its name suggests, become transparent to such a degree that a central cluster of specialized, spore-producing cells are partially visible. This is due to a thinner shell that requires less silica to create, thus it can spend more energy on reproduction as a means to stay near the surface. Spreading throughout the global ocean of Mason, the transparent gildron has become extremely successful, forming vast plankton blooms that tint the water a faint yellow.
