Filtering Gildron

Splitting from its ancestor, the filtering gildron has evolved a unique body plan. Moving about with the aid of cilia, it possess' a very primitive complete digestive tract consisting of little more than a opening in its body filled with specialized cilia dedicated for sifting detritus for the organism to use as a source of nutrients. Swimming blindly about, it lives a simple, short life, occasionally releasing spores through it rear opening.
