Mating season for grizzly bears is from May to July, according to ADW. Fertilized eggs start to develop but implantation in the uterus is usually delayed until November, when the female is hibernating. After a gestation period of six to eight weeks, two or three babies, called cubs, are born.

When they do reach breeding age, females only breed every 3 or more years. Males compete with each other for breeding opportunities and seek females each year. Grizzlies should live to be 15 to 20 years of age, and a few survive for up to 30 years.

Siberian Tiger is far better hunter than North American grizzly bear. Both grizzly bear and Siberian tiger paw swipes are equally powerful but tiger is more technical than grizzly.

However, a gorilla is a mighty foe with more stamina and fearsome strength. It’s the will to fight will last much longer than a male lion’s and if it gets its hands upon a solid branch, it can put a beating on its feline combatant.

“Wherever they go they are in view,” says Redmond. “That adds to their stress.” Nevertheless, to Redmond’s knowledge there are no known instances of a captive gorilla killing a human.

There would be no fight. A gorilla would be just a prey for a tiger. A tiger is much heavier than a gorilla and though a gorilla can be strong very strong compared to the strongest men ever on earth still has canines bigger than a leopards but a tiger is a whole lot bigger.

But in the wild, they say, tigers and lions fight quite differently: A group of 2–4 female lions would have a similar advantage over a lone tigress. They conclude that while one on one, a tiger would certainly best a lion, in the wild the lion pride could hold their own against the solitary tiger.

The Endangered Species Act makes buying, selling, importing, or exporting tiger fur or body parts a federal crime punishable by up to a year in prison and $50,000 in fines. Despite conservationists’ efforts to protect them, a thriving global black market for tiger parts persists.

Brazilian wandering spider The Guinness Book of World Records considers the Brazilian wandering spider the most venomous in the world. Hundreds of bites are reported annually, but a powerful anti-venom prevents deaths in most cases.

They do not have venom glands, fangs or any other mechanism for chemically subduing their food. Therefore, they do not have injectable toxins. Some have defensive secretions that might be toxic to small animals if ingested. So, for these daddy-long-legs, the tale is clearly false.
