Approximately 3.5 billion years ago, an extraordinary array of primitive life began to manifest itself on planet Vesta. A single cell, called Ryon, first appeared in the warm waters of the Sea of Madrone and the Manitcore Ocean. This warm stable environment permitted life to have a chance of coming forth and then evolving. After billions of years of the perfecting of the aquatic plant life, this environment was ready to host aquatic animals and support their many evolutions.

Water animals on Vesta originated from three different types of single cells, called the Sion cell, the Teon cell, and the Paon cell. These cells all broke off from the parent cell, called the Ryon cell. In time, these unicellular life forms of water animals evolved into multicellular life forms. The multicellular life forms evolved into simple water animals, which then began to form different species of modern water animals. There is a wide variety of water animal species because the oceans offered a wide variety of living environments. Species adaptations and behaviors changed many times over time as the hand of evolution pressed each species to improve, adapt or disappear.

We will only explore the descendents of the Sion, Teon, and Paon cells and their three major living habitats. Therefore, this chapter will investigate the rocky shore habitat, the kelp forest-like habitat, and the coral reef-like habitat of planet Vesta.
