The sudline is a hybrid of beadline and sudisflutans It has replaced both ancestors. It's both a cytovore and a detritivore. It has inherited most of the sudisflutans' cell structure while gaining the digestive tract of the beadline. It has lost one flagellum but gained cilia to bring in food. It uses the sudisflutans' reproductive system to reproduce now. It lives in all of the ocean and all the tropical and temperate coasts.
