Grizzlies can grow up to 8 feet long and weigh up to 800 pounds, with males being larger than females. They have a thick fur coat that ranges in color from light brown to almost black, and they have long curved claws that are well adapted for digging and foraging.
Grizzlies are opportunistic feeders, and their diet varies depending on what is available in their environment. They eat a wide range of foods, including fish, berries, nuts, roots, and even small mammals. They are also known to scavenge on carrion and to occasionally hunt larger prey, such as elk or moose.
Grizzlies are generally solitary animals, although they may come together in groups during mating season or when food is abundant. They are also known for their ability to hibernate during the winter months, during which time they can reduce their heart rate and metabolic rate to conserve energy.
