Habitat and Diet
Eastern freshwater cod are found in clear, flowing rivers and streams with rocky beds and deep holes within the Clarence River system, to significant altitudes. The size of the rivers and streams they inhabit range from very small to very large. Eastern freshwater cod are territorial and aggressive. The bulk of their diet is based on crustaceans (the large, clawed Macrobrachium shrimp and the small, clawless Paratya shrimp) and other fish, but they are powerful opportunistic predators and are also known to take insects (e.g. cicadas), frogs, snakes, lizards, birds and small mammals.

Famous quotes containing the words habitat and/or diet:
“Neither moral relations nor the moral law can swing in vacuo. Their only habitat can be a mind which feels them; and no world composed of merely physical facts can possibly be a world to which ethical propositions apply.”
—William James (1842–1910)
“I learned from my two years’ experience that it would cost incredibly little trouble to obtain one’s necessary food, even in this latitude; that a man may use as simple a diet as the animals, and yet retain health and strength.... Yet men have come to such a pass that they frequently starve, not for want of necessaries, but for want of luxuries.”
—Henry David Thoreau (1817–1862)
