Sack Foi

The Sack Foi has split from the Foi and has adapted to filter-feeding in the tropical coast. It has adapted a "belly-sac" that used to be its digestive surface. Close to the opening of the chamber are 2 feelers uses to detect the sandy bottom. Its eyes have become more advanced and can make out colors. Its "Skirt" around the middle of its body is uses for locomotion by waving it up and down. Its nervous system has also improved. It is blue in color to blend in with the clean blue waters. Along with now having a primitive mouth it also has an anus at the end of its tail. Its esophagus, stomach and intestine are all one big sack.

The sack foi has a new reproduction method for a more complex creature. When it reproduces, the end of its body grows extensions that grow clusters of buds. The extensions that the buds are attached to supply nutrients to the clusters. Each cluster grows several thousand offspring that detach when nourished enough. The clusters produce so much offspring because the young are defenseless. Only a few survive to adulthood.
