👉 Pelobiontida is a group of organisms classified into two main groups, the Pelobionids and the Oligobionids. The Pelobionids are characterized by their large, flattened bodies, while the Oligobionids have more slender, elongated forms. These organisms are known for their unique adaptations such as the presence of a large, flat body that can support an extensive network of structures and organs, including lungs, hearts, and digestive tracts.
