Chelodina longicollis

The Eastern Long-necked Turtle or Snake-necked Turtle is very common in eastern Australia and into south-eastern SA. They have a long neck and live in freshwater environments in bodies of slow-moving water like farm dams, rivers and lakes. In Drouin they can be seen at Alex Goudie lake, McNeilly wetlands and Crystal Waters.

They have shells to around 25cm long with necks almost as long. The shell is red-brown or black on the upper shell and a creamy-yellow lower shell. Dark brown markings along the shell are also very common. They also have incredibly strong jaws and webbed feet.

Eastern Long-necked Turtles are armed with defensive scent glands above each leg, turtles can squirt a liquid with a stinking and persistent odour.

Long-necked turtles are extremely tough, sometimes living in some pretty unappealing places, such as polluted creeks and even sewage treatment plants. They can also survive horrific injuries and infections, such as near-total loss of the shell, thanks to an unusual immune system but urbanization is adding to their vulnerability.

Like Sea Turtles, they come onto land and dig burrows in some soft earth into which they lay their eggs. They can lay up to two dozen eggs.

The hatchlings are completely independent. They can have a life span of more than 30 years. Eastern Long-necked Turtles eat small fish, crustaceans, molluscs, frogs, worms and insects.
