That is why bear deterrent spray only works if you use it *before* the bear goes into attack mode, and in such a manner as to not put the bear into attack mode. It has only tunnel vision, and whatever is in that vision has the complete attention of the bear until the brain activity of the bear returns to normal. Self-control and decision-making go out the window, and when a bear is in fight mode it (neurologically speaking) can neither hear nor feel The neurological activity becomes concentrated in a very limited portion of the brain-the part which deals with self-preservation. When a bear is angry, huge portions of its brain simply shut off. The heaviest gorilla recorded was a 1.83-metre (6.0 ft) silverback shot in Ambam, Cameroon which weighed about 266 kilograms (590 lb), although the latter area is within the range of the western gorilla, far outside that of the eastern gorilla.Bears have the most messed up brain-function in all of the animal kingdom. The tallest silverback recorded was a 1.94-metre (6.4 ft) individual shot in Alimbongo, northern Kivu in May 1938. A full-grown adult male Eastern gorilla weighs an average of 195 kg (430 lb) and stands 1.7 m (5.6 ft) upright and a female typically weighs 100 kg (220 lb) and stands 1.4 m (4.6 ft). The mountain gorilla is slightly smaller and lighter than the eastern lowland gorilla, but still slightly larger than the western lowland gorilla. The eastern lowland gorilla has a shorter, thicker, deep black fur, while the mountain gorilla has a more bluish color. This is why the older males are sometimes called Silverbacks. When the gorilla gets older, the entire fur becomes grayish, much like the gray hair of elderly people. The fur is mainly black, but adult males have a silvery "saddle" on their back. The face, hands, feet and breast are bald. The eastern gorilla is a large hominid with a large head, broad chest, and long arms. beringei) has only about 700 individuals. graueri) is the most populous, at about 5,000 individuals. At present, the species is subdivided into two subspecies. The eastern gorilla ( Gorilla beringei) is a species of the genus Gorilla and the largest living primate. One study found that the average weight for an inland female grizzly was around 136 kilograms (300 lb) and the average weight for a coastal female was around 227 kilograms (500 lb).Įastern Gorilla (coalition of 2) - Gorilla beringei Most adult female grizzlies weigh 130–180 kg (290–400 lb). In the Yukon River area, mature female grizzlies can weigh as little as 100 kg (220 lb).
The long guard hairs on their backs and shoulders often have white tips and give the bears a "grizzled" appearance, hence the name "grizzly." The correct scientific name for the species is “brown bear”, but only coastal bears in Alaska and Canada are referred to as such, while inland bears and those found in the lower 48 states are called grizzly bears. Their coloration is usually darkish brown but can vary from very light cream to black. Grizzly bears have concave faces and long claws about the length of a human finger. The grizzly bear is a large predator that is different from black bears due to a distinctive hump on its shoulders.
