This is one of the largest sea creatures of Sagan 4 and originated from the evolution of the starmouth. Accustomed to feeding on sea creatures, it increased its size and developed diverse coats in its body, covering its back, tail, and mouth. In the mouth, they play an important function, assisting in olfaction, filtering of water, and capture of only the foods that interest it. These coats also make them very quick. Its main strategy of hunting is to involve the prey, making many turns around its body until it dies. The great "sea dragon" is the larger predator in the ocean.
