In Play Fights, Girl Puppies Win
This is maybe similar to the last two Fun Facts. Male puppies often let female win. But, turns out it is just to let the female puppies play more. By doing this, the male puppies learn more about the female puppies.

Well, could this be similar to us, people, when we are playing together? Maybe sometimes a man let a woman win just to know her more :p. Or it is also possible because the man can't win anyway 😀
Dolphins have names for each other
This is a good lesson for anybody who plan to befriend a dolphin. Make sure to know his name first, or you will bound to call for the wrong dolphin. Though what kind of name will you name a dolphin?
From National Geographic, the answer is signature whistle. But I wonder, how does we differentiate a whistle? ._.
When playing with female puppies, male puppies will often let them win, even if they have a physical advantage.
Well, now we know that not only human does it but dogs also do. Maybe the difference is that male person did that because he is scared of the opposite sex? :p
If you lift a kangaroo's tail off the ground it can't hop - they use their tails for balance.
Kangaroos are largely found in Australia and you can try to lift their tails and see if they can hop away. Though, I suggest you be careful because they pack a powerful kick which can send you flying.
Sloths can retain their grip after death
Since they spend most of their time in trees, sloths’ muscles and limbs have been engineered to climb trunks to find food and escape predators. They spend so much time in the trees that the tree holds their life in the balance, sometimes even after they’ve died. The grip of a sloth is so strong that when they die, they are found clinging to the branch they were lounging from when they were alive!
