Hmmm, I'm not a walking encyclopedia. I go on gut feeling and stories. What I say here is therefore not per say scientific, but more anecdotal and through experience.

Many people, especially in professional capacity use tools and processes intended on increasing efficiency, but they do it wrong, achieving the opposite.

A Killer Whale Is not whale ,it's Actually a Dolphin. Despite the name, killer whales—or orcas—are not true whales. They belong to the dolphin family and are actually the largest members of the oceanic dolphin species. They're basically giant dolphins in dramatic black-and-white suits.

Don't swim away fast from sharks as they think you are prey then. 

Boop or push down on sharks head of they get too close. 

Cats will do whatever they want and they give 0 cares what you think. 

Piggy-backing on the Orcas - their pods are maternal, and each pod has a distinct language of clicks and vocalizations. They also, despite what some may think, do not mate for life. Males leave their family pod to find a mate. Afterward, the male returns home, leaving the mate and calf with their family pod. The male Orca has no hand in raising their offspring.

Ok

There are more trees in the world (on Earth) than there is starts in the Milky Way galaxy and that still blows my mind somehow. Wasteness of the galaxy versus trees on Earth.

Did you know, that the fattest animal is considered to be the Blue whale, weighing up to 190 tonnes.

Fiat currency always and forever eventually leads to a populist moment.  This is because the currency is backed by debt.  Debt requires printing money more money.  Printing money leads to inflation.  Inflation reduces purchase power.  Reducing purchasing power causes wealth inequality as people with the fiat currency's loses value and people with scarce assets retain their wealth.  This process hollows out the middle class and leads to the "Rich getting richer and the poor getting poorer".  When you are poor and you look across the way at your rich countryman many choose to  wallow in jealousy.  This leads to populism.

Did you know that Oxford University was founded centuries before the Aztec Empire?

By the time the Pilgrims settled at Plymouth Rock, Santa Fe, New Mexico, already boasted hotels and restaurants. The Old West was hopping even as the first colonists were just arriving on the East Coast.

as early as the late 1300s, large reserves of tom yum flavor-coated peanuts can be found registered in ship ledgers departing from western and northern europe, marking a radical departure from our traditional academic understanding of both soup and nut culture

Pizza is circle but always even frozen/fresh comes in a square box

cargo is sent on a ship, but shipment is usually sent to your address/mailbox

to say you slept like a baby means you were up all night, not sleeping peacefully

in ancient persia, instead of sitting in front of a fire place to get warm, you would sit in front of a wind place to cool down

Dolphins apparently have their own version of puff puff pass. They find a blowfish, wait for it to puff up, and then bat it around with some friends. The mild poison from the fish gives them a high-like feeling.
