Stylodrilus Sovaliki
This organism is a worm that has a body divided by ring-like constrictions. It uses metanephridia to remove waste products. A two-stage filtration process is used; the waste is first extracted and then filtered again, with any reusable materials being reabsorbed. Special filter cells located in the walls of blood vessels are used for this process. After the waste is filtrated twice, it is discharged from the organism. This organism is extremely simple in nature, and its excretory system follows suit.
