In NSW the Long-neck Turtle is a common sight.
The species is classified as a snake neck turtle; however, the adaptation is merely to help them opportunistically feed on their wide variety in their diet. The will eat insects, small fish, molluscs, frogs, and worms. Often fishermen will use a worm for bait and often catch a turtle by mistake, as they are so opportunistic. Often it is referred to as the sea-food diet: if they see it they will eat it.
Due to the size of the neck, they have adapted a way to curl their neck into the front of the shell. Often to the right side, rather than retract into the shell like other turtles.
Their neck also serves as a vital way to flip themselves back over, when not in the water. These turtles can be found wandering quite far between ponds, and occasionally in the middle of busy roads!
As a point of difference, their shell colour is dark brown, if not completely black in colour. The colour of slime and algae from the ponds where they reside in, later helps camouflage them in their environment.
