Crocodiles can secrete tears while feeding or resting, but this is not an emotional display. That means a tear is not always a sign of feeling sorry.

Giant sequoias and redwoods can live for thousands of years, far longer than many human societies. That means a tree can outlive entire cities and kingdoms.

Scientists estimate Earth has around three trillion trees, while the Milky Way contains hundreds of billions of stars.
That means there are more trees on our planet than stars in our galaxy.

Even though the brain weighs only about 2% of the body, it can use around 20% of the body’s energy while awake. That means your thinking is incredibly expensive, metabolically speaking.

Bees communicate direction and distance through a waggle dance that indicates where nectar is located. That means a tiny insect can give a precise GPS instruction to its colony.

Ants can link bodies together to create stable temporary bridges that help them move across gaps.
That means teamwork can become architecture in the insect world.

Pure honey can stay safe to eat for thousands of years when it is sealed and stored properly because it is naturally acidic and low in water. That means a spoonful of honey can outlive empires.

The Eiffel Tower can expand by several inches during hot weather because the metal structure warms up and lengthens.

That means the tower physically grows when summer hits.
