Sun Eater Lungeworm 

Lungeworms are limbless Lungefish that began evolving around 225 MYH. They are highly distinctive animals with worm-like bodies with only four tiny spurs that remain of their fins being present as juveniles which are reabsorbed into the body as they mature. They are very small half the length of a human arm and very terrestrial for Lung Fish hatching their eggs in shallow water and living in the leaf litter of forest floors although they are most diverse in the Coastal Lowlands where they evolved as a whole.
