Ocean Environment (Salt Water) Oceans are large bodies of salt water divided by continents. Since ocean water is constantly moving, the characteristics of the waters are constantly changing. The amount of sunlight varies by depth. Because of this, the temperature also varies by depth. The amount of salt, other minerals, and other matter in the water varies based the ocean’s location, on what lives in the water, and what pollution has been placed in the water. Most organisms live in the shallow part of the ocean because sunlight can reach down to keep the water warm and food plentiful. Some examples of organisms that live in the shallow parts of the ocean include drifters (jellyfish and seaweed), swimmers (fish), crawlers (crabs), and those anchored to the sea floor (corals). Some organisms live in the open ocean near the surface of the ocean or in the deep ocean bottom. Plankton, tiny plants and animals, float in the upper regions of the water. Some organism swim to the surface for food or air (whales, turtles, dolphins), while others stay closer to the bottom of the ocean floor (octopus). Make a Food Chain
