Bears differ from other carnivores in that the special molar teeth they possess are not specially adapted to tearing meat, but to grinding vegetation. However, to successfully sustain such a large animal on a predominantly vegetarian diet, the Black Bear must spend an enormous amount of time eating and is known to consume tens of thousands of nuts and berries per day. Because they spend about half their day looking for and eating food, the average Black Bear eats a nut or berry every second.
