Drinking 5 Liters of water can be deadly. On the hand, a fatal dose of caffeine is around 100 cups of coffee, but that can never happen because one would die first from too much water.
The Majority of Earth’s Oxygen Is Produced by Oceans
Marine organisms like plankton, algae, seaweed, and bacteria engage in photosynthesis, converting sunlight into vital oxygen molecules. Estimates vary, but experts suggest that anywhere from 50% to 80% of Earth's breathable oxygen originates in the sea.
Bananas are Radioactive
Bananas contain potassium, and because potassium decays, it becomes slightly radioactive. Eating 20 million bananas at one time might kill you due to radiation exposure. This is ofcourse unlikely to happen and even it did, radiatian might be the last reason to kill you.
A bolt of lightning is five times hotter than the surface of the sun and contains enough energy to toast 100,000 slices of bread.

Some snails can sleep up to three years straight.
The seemingly appealing extended nap of snails stems from less-than-ideal conditions and their need for moisture to survive. When faced with uncooperative weather, snails can enter an extended slumber lasting up to three years to conserve moisture.

Honey never spoils and can remain edible for up to 3,000 years.
Due to its remarkably high sugar content, it possesses natural antibacterial properties. Jars of honey dating back over 3,000 years remain perfectly edible. Archaeologists were able to find edible honey in ancient Egyptian tombs, which further validates this fact.
Honeybees can recognize human faces.
A number of experiments and studies have shown that honeybees, whom possess only 0.01% of the neurons found in humans, have the ability to distinguish and recall individual human faces.
Koalas have fingerprints that are almost identical to human fingerprints.
Octopuses have three hearts, nine brains, and blue blood
There is a primary central brain responsible for all the analysis and decision-making, accompanied by eight secondary brains situated at the base of each arm. These secondary brains serve as preprocessors for the information collected by the respective arms. About two-thirds of the octopus's neurons are located in its arms. This enables the arms to autonomously learn tasks like opening a shellfish, allowing the central brain to focus on other activities.
The first oranges weren't orange; they were green! Also the color "orange" comes from the fruit, not the other way around.

Rats laugh when you tickle them, letting out tiny high-pitched giggles in the process.
The human eye has a 576-megapixel resolution. However, we only see at about 150dpi, since that is more than enough visual stimuli for us to see objects.
Human saliva contains a painkiller called opiorphin that is six times more powerful than morphine.
