Bear is a type of mammal in the family Ursidae. There are currently 5 genera and 8 species, including the subfamily Panda and the subfamily Ursinae: Panda subfamily: Panda (giant panda); Urs subfamily: Spectacled bear (spectacled bear), Ursus Genus (Brown Bear, American Black Bear, Asiatic Black Bear, Polar Bear), Sloth Bear (Sloth Bear), Sun Bear (Sun Bear).
Among these bears, the largest is the polar bear, which is carnivorous, followed by the brown bear. Brown bears are divided into several subspecies, and the grizzly bear is one of them, and it is the largest of all subspecies. Brown bears that live in North America are called grizzly bears because their fur looks silver or gray.
According to statistics, an adult grizzly bear can weigh up to 450 kilograms, stand 2.5 meters tall, and in rare cases can grow to 700 kilograms. In front of humans, it is definitely a behemoth opponent. The grizzly bear looks bulky, but at critical moments, it can run as fast as 50 kilometers per hour. It can not only climb trees, but is also a good swimmer. It can be seen that if a grizzly bear pursues a human, it will be almost difficult for the human to escape without the help of other means of transportation. It is worth mentioning that bears also have three major weapons: bear paws, thick fat layer armor and powerful bite force. The grizzly bear is very strong. The average width of its forepaws is 28 centimeters, and the length of its claws can reach 15 centimeters. The shoulders are muscular and bulging, giving the grizzly bear greater strength in its forelimbs. If a palm is exerted with all its strength, it can exert more than a ton of force and easily break the spine. Even if the bones are not broken, the sharp claws will cause serious open wounds, which is very fatal. The canine teeth of grizzly bears are very long and their bite force is amazing, reaching 1160psi. In addition to being aggressive, grizzly bears also have strong defense capabilities. They have thick fat that can reach 25cm. This means that even if someone holds a gun, they may not be able to kill the grizzly bear if they do not aim at the vital parts.
