There are millions of majestic, mysterious and incredible species in the animal kingdom that are much smarter than you think.
These wonderful creatures that inhabit our planet will surely make you smile when you learn fascinating facts about them.
Well, let's get started. Here are our top ten fun facts about animals.
Squirrels have planted thousands of trees around the world
These furry animals are not very big in size, but they play a key role in the environment that you may not even realize.
Squirrels give life to thousands of trees around the world every year simply because they forget where they buried their supplies.
During mating, dragonflies create a heart-shaped figure with their "tails"
Dragonflies symbolize change, transformation, adaptability, and are a sign of spiritual growth and emotional maturity.
But that's not all: they also embody love in some esoteric currents.
This is probably due to the fact that during mating, dragonflies create a figure with their "tails" that looks very much like a heart. That's what love is like.
Rats laugh when they are tickled
A study was conducted at the University of Berlin to find out what happens in the human brain when tickled.
National Geographic writes that tests on rats have shown that they actually love being tickled, especially on the back.
When tickled, rats make a very high-pitched sound that is associated with laughter.
They even look for the experimenter's hand when he stops and "ask" to scratch some more!
Ducks love to surf
Ducks love to catch a few waves while on the surface of the sea or ocean.
They have been seen swimming through the ocean waves towards the shore and then returning again and again to repeat the act. Could this be their hobby?
Wild chimpanzees often get drunk
Like humans, chimpanzees love to drink (in the sense of alcohol).
Over the years, scientists have discovered an evolutionary link between human alcohol consumption and chimpanzees seeking naturally fermented alcohol.
It's called the "drunken monkey hypothesis." In the jungles of Guinea, these clever animals climb raffia palms to steal the alcoholic juice that humans collect in containers.
The total alcohol content of fermented palm sap averages 3%, which is equivalent to the alcohol content of beer, for example.
Cats only communicate with people by meowing.
Cats, our furry friends, love to spend their time lounging around us... or on us.
Have you noticed that they always meow when they are with us? It is a form of communication unique to the relationship between cats and humans.
You are unlikely to see our furry friends using this same form of communication to communicate with another cat, the only exception being kittens and their mother.
In addition, cats rub their heads against a person to make him feel safe.
Baby elephants soothe themselves by sucking their trunks
Like human babies, baby elephants are able to soothe themselves.
Babies use their fingers or a pacifier to do this, while young elephants suck on their own trunks.
The octopus has three hearts, nine brains and blue blood.
The seas and oceans are home to millions of species known and previously unknown to science.
However, the giant Pacific octopus is truly something majestic.
These eight-armed cephalopods are truly extraordinary: they have three hearts, nine brains and blue blood.
We already talked about this literally a couple of publications ago, but let's still refresh our memory of these facts.
One main octopus brain controls their nervous system, and eight other brains control each of the eight arms individually.
Two hearts pump blood to the gills, and one - the larger one - ensures blood circulation throughout the body.
In addition, octopuses are masters of camouflage while hunting and release toxic ink when threatened.
Male seahorses give birth to their young
Unlike any other living creature on our planet, seahorses are the only animals in which males become pregnant and give birth.
Male seahorses have sacs on their bellies that can hold up to 2,000 pups at a time.
Penguins use pebbles when proposing
If you've seen David Attenborough's famous film "A Life on Our Planet," you probably know that when penguins choose a mate, they stay together for life.
Just as humans propose to each other by exchanging rings, penguins use the same technique, only with a pebble.
When a penguin sees an individual he likes, he brings her a small stone to show the seriousness of his intentions.
Previously, we talked about whether it is possible to feed a dog and a cat the same food.
