👉 Exoderms are a class of organisms that are characterized by their ability to form and retain multiple layers, often referred to as "surfaces" or "layers." They typically have an inner layer that is made up of cells that produce proteins, which are then used in the outer layers. Exoderms can be found on the surface of planets, moons, asteroids, and other celestial bodies. Some exodermic organisms also live on the surface of Earth.
