Detailed explanation-2: -Australian snake-necked turtles, sometimes called common or eastern long-necked turtles, are named for their long, narrow necks. This semi-aquatic turtle is dark gray or brown with a yellow underside and is native to southeastern Australia.

Detailed explanation-3: -Oblong turtles found wandering on land may be dehydrated and will be stressed. Please rescue the turtle and call the Turtle Oblonga Network immediately. Don’t leave the turtle where it is, or put it into the water, as even minutes later it is unlikely we will be able to find the animal again.

Detailed explanation-4: -Eastern long-necked turtles are carnivores with a diverse and opportunistic diet depending on what is available at the time. They feed predominantly on small aquatic animals such as crustaceans (including zoo-plankton and yabbies) and water insects.
