It's unique marine animal in many ways, including their choice of habitat. Instead of clear, coastal waters, flat backs live in turbid coastal waters. Flatback sea turtles are endemic to Australian waters and are found nowhere else in the world. Flatback sea turtles are usually found in bays, shallow, grassy waters, coral reefs, estuaries and lagoons. They inhabit the coastal waters of western, northern and eastern Australia.

The Flatback sea turtle is smooth, waxy skin is very thin and easily damaged. The shield of the average adult is 90 inches long. It is low arched, the edge is reversed, and has four pairs of ribs scales, less than other sea turtles. The upper parts are olive-gray, while the more pale ventrally. A few scales are located on the front of the head, which also distinguish this species. The Flatback sea turtle eats a variety of organisms such as sea grass, marine invertebrates such as mollusks, jellyfish and shrimp, but also fish. It also uses soft corals, sea cucumbers and other soft-bodied creatures.


Flatback sea turtle's hatchlings are the largest of a turtle. Hatching is the most dangerous time for flat backs. Led by the low, open horizons, newborns dash for the sea. Only safety in numbers protects them against birds and crabs. However, even the sea is not safe. Sharks and fish patrol shallow waters, preying on boy waiting. Flatback sea turtles are threatened by saltwater crocodiles, dingoes, foxes, rats and lizards fall guy. Along the coast, sea eagles and herons are known to prey upon them as well. 

Although Flatback sea turtle move fast in the ocean, they are slow and defenseless on land. Male Flatback sea turtles almost never out of the water. Female sea Flatback sea turtles leave the ocean only to eggs and, for most species, nest only at night to explain. A female may nest every two to three years.

Nests can be between one and three hours. After a female drags herself on the beach, she hollows out a hole with her hind legs and deposits fifty to two hundred eggs the size of golf balls. When the last egg is laid, the turtle covers the eggs with sand, Tamps down the sand with her plastron, and flings more sand about with her flippers to erase signs of the nest. 

After about two months the hatchling turtles at night. The light reflects off the water from the sky guides them to the sea. These days, car headlights, street lights or lights on buildings near the beach, causing hatchlings to travel in the wrong direction. Waiting herons make fast meals of the other boy. All babies are on the beach in the morning are easily picked by predators or die in the hot sun. It is thought that when the surviving young adults, they return to the beach where they hatched to lay their eggs.
