George Grey, Journals of Two Expeditions of Discovery in North-West and Western Australia…
“ The habits of the turtle are to swim lazily along near the surface of the water, about half immersed, biting and smelling at the various aquatic plants which they pass, and turning their long ungainly necks in all directions. When alarmed by the approach of a native the turtle instantly sinks to the bottom like a stone, and its pursuer, putting out his foot, the toes of which he uses to seize anything, just as we do our fingers, gropes about with it in the weeds, until he feels the turtle, and then, holding it to the ground, plunges his hands and arms in and seizes his prey. ”
