Males are generally larger tan females averaging 130 to 150 pounds in weight and ranging in length from 72 to 90 inches. Females average 65 to 90 pounds. Pads on the forefeet are larger than those on the hind feet. Heel pads on both the fore and hind feet have a distinctive three-lobe appearance. Claw marks seldom show in the tracks of this species.
Deer are their favorite prey.
They have also been known to prey on beaver, porcupines, rabbits, skunks, domestic livestock, pets, and other small mammals, birds, and even fish. Larger animals are usually killed by a bite to the back of the neck. Lions usually remove the viscera and eat the heart, liver, and lungs first. These food sources are generally fed upon until consumed or they spoil. Lions generally move the carcass and re-cover it after each feeding.
