Corona's great ocean covers about 80 per cent of the planet. The ocean contains 92 per cent of all the water on Corona. Corona's ocean serve as a source of food, energy, and minerals. The continents divide the ocean into three major parts. The Videlia Ocean, Lehcar Ocean, and the Bluaqua Ocean. Corona's average depth is 13, 200 feet. Some parts reach up to 38,200 feet and others only 10,320 feet. The surface temperature varies from about 32°F-90°F. In addition, ocean temperature falls as the depth increases. Corona's ocean provides many major resources such as food, energy, mineral and medicines. The ocean's great size and little temperature change have an influence on the temperature of Corona's temperature. All these factors add to the incredible variety of living things residing in the ocean and topography of the oceans. 
 

 
Corona has many beautiful seashores. Corona's seashores can be classified into three categories: sandy shores, muddy shores and rocky shores. They are constantly changing. As the sea rolls in at high tide, most of the shore becomes part of the ocean. At low tide, the sea retreats and the same area again becomes part of the land. Corona's different seashore support a great variety of living things.Corona's seashore are an important contributor to the life and existence of many ocean plants and animals. Many of these organisms live nowhere except along the ocean's edge. Life on rocky shores is more plentiful than on any other type of seashore. A tiny organism that grows along all seashore is Sylum. These organisms swim or float on the ocean tide. Some grow into larger animals of the seashore but most remain the same. Many seashore animals feed on Sylum.  
 
 
 
 
 
Lake Augusta is the largest lake in Corona. It empties out to the the  Kuway river. The river passes through tropical forest, and marshes along its course to the sea. Lake Augusta is home to many species, some are unique to this great lake. Many species originated in the ocean. Many of its more than 100 species of fish are found only in the Lake Augusta.  
 
 

Sealoch is located in the continent of Na'im. It opens up into the ocean and is salty. It runs inland for about 4 miles. Its depth ranges from 5- 120 feet deep. Sealoch is home to a range of marine life. Its inhabitants benefit from being more sheltered than animals in the ocean.  
 
 

 
 
 
Black sea is part of trench that stretches for miles along the west coast of Soleyi. It reaches depths of 9 miles. At these depths, survival is very difficult for the small number of inhabitants that must eat bacteria or each other in order to survive. Corona's scientist believe that the trenches were formed by the continuous movement of the Corona's crust. Many unusual sea creatures have developed their own unique methods for survival in the extreme cold and darkness of the deep Black Sea trench. Many deep sea species are blind and have adaptations that allow them to detect prey in the dark. The Fizotail fish for example has a long tail with sensors that detect movement. The quadpod fish uses its four fins to prop itself up above the muddy sediment so it can smell prey. Some deep sea animals produce light. Plants cannot live in the dark trenches because they need light. Thus, the only available food for the trench animal is the remains of dead material. 
 
 
 
 

Clear Reef is home to many beautiful and unique animals and plants. In its distinct area lies different types of marine life and habitats. Clear Reef is home to the greatest variety of habitats because it contains the greatest water movement, variations in temperature, and saltiness. It stretches for 20 miles along the coast of Kapei. Scientist like to refer to Clear Reef as the jewel of the Bluaqua.
