There are many things that we don't know about animals, sometimes even species that live in our own backyards. In this article, facts about animals will be revealed and it will probably blow your mind.

Animals that can't sweat
There are a lot of animals out there that can't sweat. This might seem like a disadvantage, but it actually helps them regulate their body temperature in hot environments. These animals include camels, kangaroos, and elephants. So the next time you're feeling hot and sweaty, be thankful that you're not one of these animals!
Do animals sleep?
We all know that animals need sleep just like humans do, but did you know that some animals sleep more than others? For example, bats can sleep up to 19 hours a day! That’s more than most people. And while we all know that lions take naps, did you know that they can sleep up to 20 hours a day? That’s a lot of time spent sleeping!
Animal signs of depression
Animal signs of depression are often subtle and easy to miss. But if you know what to look for, you can help your furry friend feel better.
Here are some signs that your animal may be depressed:
- Changes in sleeping habits. If your animal is sleeping more or less than usual, it may be a sign of depression.
- Loss of appetite. Another common sign of depression in animals is a loss of appetite. If your furry friend isn’t eating as much as usual, it could be a cause for concern.
- Changes in energy levels. Depression can cause animals to become either more or less active than usual. If you notice a change in your animal’s energy level, it may be a sign of something more serious.
- Withdrawal from social interaction. Animals are social creatures, so withdrawal from family and friends is another symptom of depression. If your animal seems uninterested in playing or being around others, it could be a red flag.
- Unkempt appearance. Depression can lead animals to neglect their appearance. If you notice your animal isn’t grooming itself as much as usual, it could be a
Animal gestation periods
Did you know that the gestation period for elephants is 22 months? That's almost two years! And if you thought that was a long time, consider this: the longest recorded gestation period belongs to the beaver, at an incredible 105 days.
Other animals have much shorter gestation periods. For example, did you know that mice are only pregnant for about 19 days? And hamsters for only 16 days? So the next time you see a mother mouse with her babies, remember that she was pregnant for less than three weeks!
Sloths: the slowest animal in the world?
Did you know that sloths are the slowest animals in the world? That’s right, these little creatures move so slowly that they’re practically stationary! In fact, they move so slowly that algae can grow on their fur!
While this might seem like a negative trait, it’s actually quite beneficial for sloths. Their slow movements make it difficult for predators to spot them, and their furry coats provide excellent camouflage in the trees.
So next time you see a sloth, don’t be too quick to judge – they may be slow, but they’re also one of the smartest, most elusive animals around!
Animals with more than one stomach
Did you know that there are animals out there with more than one stomach? That's right, there are creatures walking (and swimming and crawling) around this earth with multiple compartments in their digestive system. And while you may think that having more than one stomach is just a way to store extra food, there's actually a lot more to it than that.
For example, did you know that cows have four stomachs? That's right, four! The first stomach is called the rumen and it's where most of the digestion takes place. The second stomach is called the reticulum and it's responsible for storing food. The third stomach is called the omasum and it helps to absorb water and nutrients. And finally, the fourth stomach is called the abomasum and this is where the final stage of digestion occurs.
So why do cows need four stomachs? Well, they're mostly herbivores which means they need to eat a lot of plants in order to get all the nutrients they need. And since plants are not very easy to digest, having multiple stomachs helps cows break down their food so they can absorb all the nutrients they need.

Animals that have become extinct
It is estimated that 99.9% of all species that have ever lived on Earth are now extinct. While some of these extinctions were due to natural causes, many were the result of human activity, such as hunting, habitat destruction, and the introduction of new species into an ecosystem.
Here are 3 animals that have become extinct in recent history:
1. The Passenger Pigeon
Once the most common bird in North America, the passenger pigeon was hunted to extinction by humans in the 19th century. Over a period of just a few decades, this species went from being one of the most abundant animals on the continent to being completely wiped out.
2. The Dodo Bird
The dodo bird was a native of the island of Mauritius, east of Madagascar. It was a big bird, weighing up to 40 pounds, but it was unable to fly. This made it an easy target for hunters and also for introduced animals such as rats and pigs, which preyed on its eggs. The last dodo bird is thought to have died in 1681.
3. The Great Auk
The great auk was a large seabird that once inhabited the coasts of North America
