Hello my dear Steemians!

At times it feels that you know everything and seems as if you have all the knowledge and that nothing can surprise you, until you accidentally overhear someone reveal something you've never heard off. We bring you some unheard facts that will make you think twice.

1. Like the fact that a blue whale's heart is so gigantic that a human being can actually swim through its arteries. Weighing around 1300 lb it is the size of a small hatchback. Beating at a rate of 8- 10 beats per minute, it can be heard from over two miles away.

2. Despite having a huge heart its throat is as big as a saucer. During feeding season massive volumes of water can be taken in, which then passes through baleen plates trapping tiny food in them. Summer is the peak season when blue whales can feed up to 4 tones or more food everyday. That’s 40 million krill a day.

3. Hippopotamus's milk is pink. Yup, you heard that right! Hippos just like every mammal produces white or off-white milk. Hippos don’t have any seat glands, but they do carry mucus glands, which secrete an oily liquid also known as “blood sweat”. This secretion turns the milk to a baby pink color.

4. Honey never expires. Not in a year, not in 3 --- never. It may change color and turn to crystallized form, but will always be stay safe to eat. If your honey has crystallized, just place the jar in hot water with its lid removed until the crystals turn to liquid.

5. According to the ratio of ants to humans, there are around 1.6 million ants per human being in the world. the combined overall weight of all these ants and all the humans on the planet is equal. Ants being a biologically strong species have conquered all over the world. Ants are as old as dinosaurs and have survived the mass extinction some 65 millions years ago.

6. An octopus carries three hearts, nine brains and blue blood. Two hearts pump blood to the gills, while the third one circulates it around the body. It is also known as the “Escape master” because of its rather spooky skill. It can squeeze through the tiniest hole and flee.

7. It rains 'Diamonds' on Saturn and Jupiter. This is due to the high amount of crystal carbon present in the atmosphere of thee planets. Huge lightning storms turns methane into soot(carbon) which then falls down turning into lumps of graphite and then diamond. The biggest of them would be a centimeter in size, but big enough to make a ring out of it.

8. This is how our blue sky would look like if Jupiter and Moon were the same distance from the Earth. Pretty yet scary. The gravitational pull alone will produce massive waves around the Earth’s oceans which will sweep the land away. Huge asteroids will be directed towards the Earth destroying it completely.

9. There are ten times less cells than bacteria population in a human body. Being way smaller than cells, they share only 1%-2% of our total body mass. An average human being carries over 100 trillion microbes which makes 90% of our body.

10. The "Turritopsis Nutricula" a jellyfish is the only known life on Earth that is biologically immortal. Found mostly in the Mediterranean Sea and the waters of Japan. It can literally hit the reset button and slip back to the earlier development stages if injured or threatened.

11. Formerly, Feng shui was the art of choosing the right place for a grave. It was practiced in Chinese funeral traditions. Chinese believed the location of the grave is important in order to pass positive energy flow from the deceased to the ling family members.

12. The chances of you drinking a glass of water that contains a molecule of water that once passed dinosaurs is almost a 100%. The water on our Earth is the same as it was 5 billion years ago. Only a small amount have escaped into the space. No new water has formed since then.

13. Frankenstein was not a monster, but a creator. It is the creature that Frankenstein created became a monster. However , it was the misconception of the humans that led to the isolation of the creation and led him to be a monster.

14. Catfish have four times more taste buds than that of humans. A staggering 27000 of them. The taste buds are so sensitive that they pick up the slight tastes of different molecules. They are located all over its body but mainly its four whiskers around its mouth. The whiskers not only allow it to detect prey nearby but to get its exact location.

15. Sand looks beautiful under a microscope. Each sand grain is about one-tenth of a millimeter, the smallest thing a naked human eye can see. Every single grain is different. No two grains look alike.
