The results of a routine checkup at the Oregon Zoo in the United States caused a stir online when the X-ray images of some of their animals were shared on Twitter.
As part of the procedure, the animals are photographed and scanned to ensure they are in good health.
Mysterious images reveal that a beaver's tail has a bone that reaches to the tip and an x-ray of a snake reveals the hypnotizing vertebrae that curve and extend along the deadly python ball.
Other images show the difference between birds (an owl) and flying mammals (a flying fox) and a hedgehog with gas trapped in its stomach.

The flying fox of Rodrigues (pictured) is actually a species of bat called Pteropus rodricensis and is only found in the wild in Rodrigues, an island in the Indian Ocean that belongs to Mauritius. Exceptionally long fingers can be seen over the animal's arch, since the wings are indeed webbed hands, a remarkable difference between a bird and a flying mammal
The python ball (Python regius), also known as the royal python, is found in sub-Saharan Africa and kills its prey by contracting and crushing it. It is not poisonous and the name comes from a tendency of the animal to curl up in a ball when threatened or stressed.
The beaver's spine extends beyond the end of its body and far into its tail (pictured). The extended vertebrae help strengthen the tail that helps animals swim and build curses. Beavers have hind legs, a wide and scaly tail and can be very territorial
WHAT ANIMALS DO YOU SEE IN X-RAY IMAGES?
1. Rodrigues flying fox
2. Python ball
3. the beaver
7. Fat tail gecko
10. dwarf mongoose
12. wolf eel
13. Armadillo of three bands.
The Oregon Zoo shared the images for. Twitter this week and captivated people from all over the world who saw the animals in a new light.
One user said the zoo should sell copies of the images to raise money for the zoo.
Another was a step further and said: "I would totally buy a calendar of these shots."
A particularly observant admirer commented on the sinuous tail of a chameleon's tail.
Emma McArthur said: & # 39; The tail of the chameleons looks like a Fibonacci sequence.
A Fibonacci sequence is a series of numbers where a number is found by adding the two previous numbers.
When applied visually, it creates swirls that diminish and examples in nature include the Milky Way, the human body and even the appearance of pineapples.
Toucan play that game! This Toucan toucan is one of the most recognizable birds instantly in the world, but the X-ray images reveal that the structure has no bones and eliminates the iconic orange of the animal.
The Oregon Zoo houses a variety of animals including a turtle (left) and a tiger (right). The hard and dense shell of the turtle makes it difficult to see the internal bone structure as the X-rays struggle to penetrate, but the skin and coat of the tiger are easily removed to provide a removable view on the lethal legs of the large legs of the cat world
The fat-tailed gecko (Hemitheconyx caudicinctus) is a nocturnal gecko that lives on the ground. This specific type of gecko has mobile eyelids, vertical pupils and does not have adhesive sheets (sticky feet) as other types do.
Here you can see the surprisingly long legs of the owl (pictured), as well as the long & # 39; arms & # 39; which make up most of the feathered part of a bird's wings.
This chameleon had its skeleton represented while it was perched on a branch and its iconic coiled tail can be distinguished with the spine that continues to the tip of the tail. The chromatophores that allow the animal to change color are found on the skin of the camouflage expert.
WHAT ARE THE X RAYS?
The X-rays got their name from the mystery that surrounded them when they were discovered for the first time.
X-rays are a form of electromagnetic radiation that varies between 0.01 and 10 nanometers in length and are high in energy. The only electromagnetic waves with more gamma rays of energy and this allows X-rays to penetrate through most materials.
They bounce off the bone, but they go through most of the skin, fur and organs, and are often used to see the skeleton of a person or animal.
Wood and most other organic materials are not detected, but you can see metals and other dense shrapnel.
By responding to one of the 15,000 people who liked the initial thread on the social networking site, the zoo revealed how the images came to be.
He said: "We received the images from our veterinary staff, and in the mail, we intensified the black and white levels to increase clarity and reduce noise."
The zoo has yet to respond to the fervent reaction of social networks and repeated calls to get impressions of these amazing images.
The dwarf mongoose (pictured) is only eight inches (20 cm) long and weighs no more than 300 grams. These tiny creatures live in large social groups that can reach up to 40 members.
The long legs of a flamingo (in the image) can be seen in this X-ray image, with long feet and slender legs captured. The ring around the foot of the bird is probably an identification marker for the owners.
The wolf eel (pictured) is one of the ugliest animals in Oregon zoon and the sight of its skeleton seldom rescues its hideous reputation. These frightening creatures can grow up to 7 feet and 10 inches (2.4 m) in length and 41 lb (18.4 kg) in weight
The three-banded armadillos (pictured) are native to Brazil and live on a diet almost exclusively of ants and termites. The armor is made of non-superimposed keratinized scales, which are connected by flexible skin bands. When they feel threatened, they can snuggle in a ball with the vulnerable fragments of the animal protected by the armored sections.
Here you see a hedgehog with a dark spot: gas in the stomach and the pointy creature that fills the hedges looks very different when soft tissues are removed
