The Silverback gorilla can lift up to 10 times its body weight on average: a total of about 1,800 pounds, according to the Guinness Book of World Records. This makes them one of the strongest living animal species on Earth. Though they are feared, the Silverback gorillas will only use their strength when they feel threatened.

In the early 20th century, those who resided in North Frisia under Prussian rule were not allowed to raise the Danish flag. But some crafty North Frisians took action by breeding a pig, known as the Danish Protest Pig, to be red in color, with a large white stripe around its belly—thus creating an animal version of the flag. As they technically did not break the law, and because it wouldn't have been feasible to ban the breeding of pigs, the Danes successfully protested Prussia.

Benin, a country in central Africa, is notable for having the highest birth rate of twins in the world. While the world average is just 13 twins per 1,000 births, Benin more than doubles that rate, at nearly 30 twins per 1,000 births. There's no single factor that causes this, but genetics, diet, and even the mother's height are thought to play a role.
