Case Mucusworm
M. faceroglutinus evolved from populations of Mucosa bitentaculum that moved north to zone 1. They reach around 3cm in length. They have adapted to live with Aquaplortatus invictus. M. faceroglutinus uses its mucus as a cement to make a case of sand on the bark-like part of A. invictus. It will sit in its case when not feeding. The anus it still just below the head so they can release waste without have to extend very far out of their case. It will emerge, exposing up to 2/3rds of its body, to feed by sweeping particulate matter, plankton, and algae caught on the leaf with its appendages into its mouth. Their reproduction is similar to M. bitentaculum, they release sperm into the water, the sperm will be caught on the leaves of A. invictus where other M. facerglutinus will take the sperm into a special tubule connected to the digestive tract that leads to a chamber where eggs are stored. Once fertilized the eggs move down a tubule that opens into an atrium where nutrient rich fluids, produced by the parent, are released. The young stay in their parent until they develop the paired appendages and they resemble the adult but smaller. Once they have reached this stage they leave the atrium through a tubule that opens into the anus where they emerge from the parent and swim away to find a place to create their own case and live.
