The Amazon Rainforest is one of the largest and most well-known rainforests in the world. This fascinating and unique place is home to an estimated 40,000 plant species, including 16,000 tree types, as well as thousands of animal species. We know a lot of them, and many more are being discovered on a regular basis, meaning that there is still a lot we can learn about the most important place for the planet we live in.

For this reason, it's not too surprising that this place oozing with biodiversity has quite a few unusual plants, trees, and animals. From a lizard that can run on water to a plant that resembles a silly toupee, from a flower that camouflages itself to blend with pebbles to a bird that can stand motionless during the entire day, all of the most unusual plants and animals living in the jungle are put together in this list of the most unusual images ever caught in the Amazon Rainforest. Besides, there are also a lot of interesting phenomena happening in the jungle, some of which still require an explanation, and you'll learn all about them from this article, as well!

But be warned: if you've ever wanted to visit the Amazon Rainforest - this article might make you change your mind and just leave these bizarre creatures in peace...

25 Glass Frog

A glass frog is a unique creature that wouldn't need to do an X-ray to take a look at its inner organs.

Its head and limbs are lime green, but the abdomen of this unusual frog is completely transparent, so all inner organs in it can be clearly seen without any additional means.

This frog is very small (about 2.5-7.5 centimeters or 1.2 to 3 inches in length) and, according to Rainforest Cruises, it's considered that the transparent abdomen helps them take on the hue of the surrounding vegetation and hide from the predators.

24 Jesus Lizard

This lizard was called Jesus Lizard for a simple reason - it can walk on water while fleeing from predators or trying to catch a meal. The scientific name of this reptile is common basilisk and it lives near small water bodies, such as rivers, lakes, and ponds. The lizard can also swim, in case it accidentally submerges under the water.

But let's see how the Jesus Lizard walks (or should I better say runs?) on water.

The thing is, on its toes it has flaps of skin that create an air pocket, helping the reptile to enhance the surface tension and briefly support its weight on the water.

This way, it can run for about 20 meters! Amazing, isn't it?

23 Pink Dolphin

The pink dolphin, aka the Amazon River dolphin or boto, is one of the most famous residents of the Amazon. Scientists still don't know why these dolphins developed this kind of coloration, but according to one of the most common theories, it's due to blood capillaries located close to the surface of their skin.

Probably due to the large size of this dolphin (it can grow larger than a human), there is a legend about this species.

It's believed that in the evening, the pink dolphin turns into a man to seduce and hypnotize unsuspecting young women.

22 Basket Cocoon

No, it's not some kind of little sack created by human hands. This elaborate basket cocoon was woven by the urodid moth for its larva to grow to maturity. The silken string on which this cocoon dangles can be as long as 30 centimeters (1 foot). Probably, it prevents the larva from being eating by the ants.

And, on the other hand, its bright orange color serves as a warning to predators, hinting that the cocoon can be poisonous.

Doesn't it make you think that the way we, humans, grow into adulthood is kinda lame?

21 Lithops Julii

Lithops Julii, also known as living stones or pebble plants, are really weird plants found in the Amazon Rainforest. At first sight, they aren't different from stones and pebbles, among which they are growing. But if you look closer, you might notice that they're actually flowers camouflaging themselves to avoid being eaten.

It's interesting that Lithops were first discovered in South Africa by botanist and artist William John Burchell, who studied what he thought was a "curiously shaped pebble".

I can imagine how amazed he was to see a flower peeking out of this pebble one day!

20 Bullet Ant

The bullet ant is known as the largest kind of ants in the world. It can be as large as your pinky finger, but it's not the most horrible thing about this insect. The ant was given its name for its potent sting that can cause excruciating pain in the area it bites. According to the people who were bitten by it, this pain is equal to that of being shot by a bullet. And it doesn't go away quickly. Some victims report experiencing this horrible pain for as long as 24 hours!

I guess it's the kind of thing that can keep you far, far away from the Amazon Forest...

19 A 'Spaghetti' Passion Flower

We all know what a passion fruit is and most of us love the juice squeezed out of this tropical fruit. But did you know how it grows and how its flowers look like? Now you do - just take a look at the photo above!

In fact, the passion fruit is a vine that can stick to pretty much anything and grow up to 6 meters (20 feet) per year.

It's interesting that since it doesn't like too much sun and heat, it tends to grow toward the shade in extremely hot conditions.

Also note that the very passion flower you see in the photo above is the new species of this plant, found in Pará state, north-eastern Brazilian Amazon in 2013.

18 Potoo

Potoos live throughout the Amazon Rainforest. Being masters of disguise, these nocturnal creatures usually spend their days on the top of a dead branch in a lifeless pose, without a single motion, perfectly blending with the surroundings. This camouflage is so effective that it's really hard to spot the bird on the tree even to make a photo. It's easy to guess that this statue-like behavior in the daytime is supposed to protect the potoo from predators.

But at night the potoo wakes up and flies away to catch insects. And as soon as the day breaks, they come back to their motionless way of life.

17 Pitcher Plant

The Pitcher Plant is a carnivorous plant that catches its prey with the help of its foliage that looks like a pitcher. Inside of this pitcher, there is a sweet liquid that smells like nectar, attracting the insects to get inside. But once they crawl into the pitcher, they can't escape it and, eventually, they are going to be digested by the plant.

Interesting fact: the Pitcher Plant is also called the "Monkey Cup" because it's known that monkeys like to drink rainwater accumulated inside of it.

16 Spider-Shaped Decoys

According to Rainforest Cruises, this species of spider has been discovered only recently and it's a really amazing one. The spider itself is very small, reaching only about 5 millimeters (0.1 inches) in length, but the decoy it builds in its web is much larger. This fake spider, complete with multiple legs, is created with the help of dead leaves and debris.

Researchers are still trying to figure out why this spider does all this work to make it look like a large spider is sitting on its web.

But most likely, it does it to confuse predators and increase its chances for survival.

15 Kinkajou

Just look at this cute creature crawling down the branch! Isn't it lovely? If you agree with me and also feel like you're falling in love with this furry fellow, let me tell you a couple of things about it.

First things first, it's called a Kinkajou and it's a relative of a raccoon. It has golden fur and a long tail with which it can grip branches. Locals also call it a honey bear, because it likes to eat fruits. The Kinkajou has a long tongue that helps them to get a fruit hanging on a branch and even lick nectar from flowers!

14 The Boiling River

In the Peruvian Amazon, there is a river, where you certainly wouldn't want to take a dip. The temperature of water in this river can be over 93 degrees Celsius (200 °Fahrenheit) and steam often rises from its surface, as if warning all living beings about the danger. It is still unknown how this so-called boiling river appeared and why it has such an extreme temperature. According to one of the theories, a drilling company accidentally ruptured a geothermal system and released gasses from inside the Earth into the river.

But locals have another opinion, thinking that this river is a place of enormous power, so they often gather on its banks to pray and sing.

13 Vanzolini Bald-Faced Saki

Last year, Laura Marsh, a director of the Global Conservation Institute, gathered a team of scientists, photographers, conservationists, and local guides to take a 4-month-long expedition to the Amazon forest and find an elusive species of saki monkeys that hasn't been seen alive in 80 years. This species is called the Vanzolini bald-faced saki.

To the great happiness of Marsh, they found this monkey recognizable by its golden arms and legs and shaggy hair. When she first saw it after years of looking for it, Marsh burst into tears. "It was fantastic," she said later in an interview with National Geographic. "I was trembling and so excited I could barely take a picture." We can only imagine how much it meant to her!

12 Ancient Geoglyphs

Another recent discovery about the Amazon Forest doesn't concern any of the plant or animal species dwelling there. It concerns the very land on which the forests are growing.

Not long ago, a series of strange geoglyphs were found on the ground of the Amazon rainforest. So far, approximately 300 geometric designs carved into the ground were located there. According to TreeHugger, they were built by the ancient people inhabiting the area about 700 years ago. However, we still don't know why these geoglyphs were created and how it was done, because at that time there were no tools to create them.

11 Heliconia Flower

This unusually looking flower is commonly known as the Hanging Lobster Claw, but its scientific name is the Heliconia flower or Heliconia latispatha. This plant is rather large, ranging from 0.5 to nearly 4.5 meters (1.5–15 feet) in length, while their leaves can be about 15–300 centimeters (6 inches - 10 feet) in size.

Since Heliconia likes warm and humid conditions, it strives in the tropical climate of the Amazon Rainforest, perfectly coexisting with other species. Its nectar is food for hummingbirds, who, in return, serve as pollinators of the plant.

10 Solar Halos

Solar halos are an amazing phenomenon that has been spotted at least once above the Tambopata River in the Amazon Rainforest. According to Live Science, the halos are created due to the refraction and reflection of the sun's rays by ice crystals in cirrus clouds high in the atmosphere.

It's an incredibly rare optical event that can occur only in specific conditions, resulting in this impressive view.

So if you ever come to the Amazon Rainforest and get to see it, consider yourself an extremely lucky person!

9 Puss Caterpillar

From one angle, this weird thing resembles a tropical fruit. From another one, it looks like a very small and extremely furry mammal. And if you take a closer look at it, you might even think that it reminds you of a toupee of a very famous financier, who is now ahead of one very large country (if you know what I mean)...

But, in reality, it's none of it. It's a larva of a flannel moth, also called a puss caterpillar. Keep in mind that it only looks fluffy and attractive, while its spiny hair can be poisonous.

8 Victoria Amazonica

It seems that everything in the Amazon Rainforest is unusual because even the water lilies look like nothing else in this world. Named after Queen Victoria of the United Kingdom, the giant water lily Victoria Amazonica is so impressive that if you see it once during your jungle tour, you'll never forget it.

This plant can reach 3 meters (over 9 feet) in diameter and it supports quite a large weight, so even an average person can easily lie down on it. Just be careful, because Victoria Amazonica has thorns in its leaves that protect the flower from predators.

7 Peanut Head Bug

Here is another weird insect inhabiting the Amazon Rainforest. The most unusual thing about its appearance is a bulbous protuberance from its head that resembles an unshelled peanut. So its name is rather logical - it's a Peanut Head Bug.

Even though the reason for this appearance is uncertain, according to some researchers, this insect uses its peanut-like head to look like a lizard and confuse predators.

It makes sense because otherwise, the bug is completely defenseless. Let's hope that this kind of defense mechanism actually helps the poor insect to survive.

6 Walking Palm

Remember Ents, the walking trees from Tolkien's Lord of the Rings trilogy? It turns out that they have a real-life lookalike that grows in the Amazon Rainforest. Commonly known as the Walking Palm and scientifically known as Cashapona, these unusual trees have a 20-meter (65-feet) trunk supported by its outside roots that can reach up to 1.5 meters (3 feet) in length.

There is a theory, according to which, the Cashapona trees actually move through the forest, due to their roots growing toward sunlight and replacing the older ones. However, not all scientists support this theory.
