Habitats
Sea turtles can be found in all the world’s oceans, from the warm waters of the tropics to the cooler waters of the temperate zones. Each species has its preferred habitat, which ranges from coral reefs to open ocean and from shallow coastal waters to deep-sea trenches. (See Also: What Are The Types Of Turtles)
Leatherback sea turtles are found in the open ocean, where they feed on jellyfish and other soft-bodied organisms. They are known to dive to depths of up to 1,000 meters (3,300 ft) in search of food.
Green sea turtles are found in shallow coastal waters, including coral reefs, estuaries, and mangrove swamps. They are herbivores and feed on seaweed, seagrass, and other marine plants.
Kemp’s ridley sea turtles are found in the Gulf of Mexico and the Atlantic Ocean, where they feed on crabs, shrimp, and other crustaceans.
Olive ridley sea turtles are found in the warm waters of the Pacific, Indian, and Atlantic Oceans, where they feed on crustaceans, mollusks, and other marine animals.
Loggerhead sea turtles are found in the temperate and subtropical waters of the Atlantic, Pacific, and Indian Oceans, where they feed on crustaceans, mollusks, and other marine animals.
Hawksbill sea turtles are found in coral reefs and rocky coastlines, where they feed on sponges, sea anemones, and other marine animals.
Flatback sea turtles are found in the shallow coastal waters of the Indo-Pacific region, where they feed on crustaceans, mollusks, and other marine animals. (See Also: What Do Arrau Turtles Eat)
