[Animals] The 10 most exotic animals that interest scientists

[SnO]

Scientists go far in the search for aliens and other extraterrestrial beings, although some forms of life on Earth are stranger than what humans might imagine from the strangeness of the inhabitants of distant worlds, and therefore the French magazine L'Obs presents a series of 10 animals with strange powers Or, at least, you can't imagine what it really is like by looking at it.

 

 

In an article written by Jean-Paul Fritz, the magazine gives a summary of these wonderful and strange animals at the same time, which are realistic beings that live in nature.

This small Mexican native that lives all its life in the water has a strange face with a bump of hairs behind its head that represent the gills, and remains most of the time in the larval state, without metamorphosing into its adult form, although this does not prevent it from reproducing.

This animal also has regeneration capabilities that have caught the attention of the scientific community, as it - says Emmanuel Cora Costa, a biologist at the University of La Plata (Universidad Nacional De La Plata) in Argentina - regenerates almost everything in its body; He regenerates limbs, heart, lungs, jaw, eyes, and even recreates part of his brain if it's damaged, all without scarring.

"This animal regenerates every organ that has been injured, if not fatally injured," says Parker Flowers of Yale University, who is part of a team studying the miracle salamander's genome, and is therefore invaluable to researchers interested in the human body's ability to repair itself. Unfortunately, it is threatened with extinction in its natural habitat.

The naked mole rat is a cold-blooded, furless mammal (Eurek Alert)
The rodent that lives like an ant
Scientists call it "heterocephalus", which means that its head is irregular in shape, but most people call it a "naked mole rat" because it is devoid of hair, and it is almost deaf and blind, but it has some amazing characteristics, the most important of which is its way of life, It lives in colonies in tunnels, with a very strict social hierarchy and under the authority of the queen, which means it is closer to the organization known to most insects.

This mole has a language or languages such as chirping, and recent studies have shown that each colony has its own dialect, and the mother is the one who decides the language that will be spoken in her colony.

The mouse has another amazing feature. It is a cold-blooded mammal that does not feel most forms of pain. It is also able to survive in almost oxygen-free environments by "transforming into a plant", or more precisely, by behaving in the same way that plants do. As the team of Professor Thomas Park of the University of Illinois explains.

What draws the attention of biologists and geneticists to this animal is its immunity to cancer, as researchers at Cambridge University discovered that these animals have the same susceptibility to cancer as other species, but the way their cells are organized in their bodies was a mechanism to combat this disease.

This animal was transferred to the International Space Station, studied, and is found all over the planet, and an Israeli probe that contained a few thousand of it crashed on the surface of the moon in April 2019, and it is very likely that these organisms survived, even in a state of hibernation.

Although the water bear cub is microscopic, it has enormous capabilities. It is a slow gait and can survive the vacuum of space, temperatures near absolute zero, boiling water, dangerous radiation and powerful impacts such as those of a rifle bullet.

This organism can survive in hostile environments, as it solidifies completely and then returns to life, but the only negative it has is that global warming will be harmful to it, as a group of scientists from the University of Copenhagen showed that water bears do not She loves high temperatures for long periods.

Blob is a single-celled organism that does not have a brain, but it has a high level of intelligence (French)
Blob.. a memory without a brain
The blob occupies the second place in human interest after water bears directly, and it is not an animal, plant, bacteria, mold, or virus. Made of interconnected tubes that can span several metres, it has no organs, let alone a brain, and is nonetheless capable of learning and communication.

The writer wondered: How is it possible to memorize without nerve cells? However, French researchers from the Animal Cognition Research Center explained in 2019 that "the blob learns to carry a substance by absorbing it," and a German team this year shed light on this puzzle, saying, "The structure of this object's network can serve as a memory of the past," said the professor. Karen Alim, co-author of this study.

An animal awakens after 24,000 years
The writer said that a microscopic animal woke up from a hibernation that lasted 24,000 years, as these microbes were discovered in the permafrost in Siberia by a Russian team, who were able to determine the history of the frozen soil layer in which they were present,
