1. Cold-blooded, long-lived, cancer-resistant --- saber-toothed naked mole rat
Cold-blooded, low metabolic rate, painless, visually absent, tolerant to high concentrations of carbon dioxide.
Saber-toothed naked mole rat
Naked mole rats can live up to 30 years, about ten times the lifespan of other rodents, and they never have a deteriorating body until they die, and they can reproduce until they die, and keep their appearance and brain tissue from aging. Scientists at the Wellcome Trust Center at the University of Oxford in the United Kingdom said that the naked mole rat gene will one day enable humans to achieve a longer lifespan and ensure strong reproductive ability.
If we understand the evolutionary development of organisms and can change them to some extent, then theoretically humans can live to be 200 years old. Naked mole rats have some strange features that scientists can't answer. They are not simply a cold-blooded mammal, but they can also fight cancer, they can eat poisonous plants at will, and they can cope with high temperatures. On the other hand, their eyesight is very poor, and most of their lives are spent in underground caves.
2. Giant pandas in the water --- white-tipped dolphins
White-tipped dolphin
White-tipped dolphins are endemic freshwater cetaceans in China, only produced in the middle and lower reaches of the Yangtze River, shy by nature, rarely jumping out of the water, known as "giant pandas in the water". The white-tipped dolphin is a family of its own, listed as a national first-class wild protected animal, and one of the 12 most endangered animals in the world. On 8 August 2007, a report was published in the royal Society's Journal of Biological Letterhead, officially announcing the functional extinction of the white-tipped dolphin.
3, the largest mammal - whales
Baby whales feeding
Whales are the largest animals in the world that live in the ocean. The whale is much like a fish in many ways, but it is not a fish, and he, like the man cow and horse, is a mammal. Whales live in the water all their lives, but they often have to surface to breathe air. Baby whales also grew up in their mother's belly, although they were born in the ocean, they were the size of elephants after birth, but after birth they still had to drink their mother's milk.
4. The smallest mammal- the shrew (qú jīng)
Shrews
Well, I also looked up the dictionary to know how to read it. They are generally only 4 centimeters long and weigh only 2 to 5 grams, which is not as big as a human thumb. Widely distributed and with a long history, they have lived on Earth for hundreds of millions of years and are the first animals to evolve a placenta.
The smallest of the shrews, the Etruscan shrews, weigh less than two grams, although small, but can eat, can eat two to three times their own weight every day, this is because the shrew metabolism is very fast, the heartbeat can reach more than 1000 times a minute.
5, the only mammal that can spread its wings and fly - bats
bat
Bats have wings, but they are not birds. Bats are mammals like humans, and the skeletal structure on the wings of bats is similar to that of human arms and hands. And they also have finger-like claws on their wings that can easily grasp objects. Bats have very weak eyesight and can hardly see anything, but bats emit an ultrasound, and with it, bats can fly unimpeded!
6. Monkey with Peking Opera face - Mountain Fish (shānxiāo)
mandrill
Because of its long face, the face is bright red and blue, the surrounding coat color is darker, the bright red nose bridge is slightly terrifying, in the ancient legend, it is a kind of monster, to see that I am actually more like born with a Peking Opera face.
The adult mountain fish has a violent, fierce and aggressive personality, can fight with medium-sized beasts, launch anger, even lions have to retreat, and sometimes attack animals such as poisonous snakes. The mountain fish also has a fairly high IQ, comparable to that of baboons, and is one of the most intelligent primates.
7, the strangest mammal - platypus
The "platypus" is considered to be the strangest mammal in the world because it has many strange features on its body: 1. No teeth in its mouth; 2. Sweat is like milk; 4, the hind feet are poisonous; 4, contains 10 sex chromosomes.
In 2008, scientists deciphered the entire DNA of the platypus, and the results were astounding: the platypus' genome contains genes from reptiles, birds, and mammals! One of the reasons platypus are classified as mammals is that they have mammary glands, hair, and three bones near their middle ears.
Platypus is a single-ampere, urinating, defecating, and sexual reproduction all in one hole.
Platypus are expert swimmers and like to look for insects and shellfish in rivers.
Platypus' mouths are covered with electrical sensors that can be used to locate prey in muddy riverbeds.
Male platypus have stingers behind each of their hind legs, which come in handy when fighting for territory.
Platypus fur comes with fluorescence. When placed under ultraviolet light, their brown fur reflects a blue-green color.
8, the most terrifying mammal - Mausaki
Mausaki
Also known as sangsaky because of its distinctive fur, Mausaki is a unique species in the Amazon that is rarely seen. These colorful monkeys spend almost all of their lives in trees, which avoids dangerous creatures, which is actually a good thing, because if you see it with your own eyes, you will also be scared half to death.
9, the mammals that sing in the middle of the night --- night monkeys
Night Monkeys
As the name suggests, it is the only nocturnal higher primate that lives in the rainforests of South America and lives most of the time in the canopy 30 meters above the ground. Night monkeys communicate primarily by calling. Its call is complex and surprising, not only can make a "chirping" scream, but also a thunderous "rumbling" sound, in addition to the gong-like "hissing" sound, people generally hear their voices first.
10、 Armadillo (qiú yú)
Armadillo
The armadillo is a species of armadillo, found only in Argentina, and is very small (about 12 cm). Due to its small size and ability to punch holes quickly, even the Argentine armadillo is very rare.
11. North American ring-tailed cat bear
North American ring-tailed cat bear
This species is not endangered. North American ring-tailed cat bears are found in the southern United States, but are not yet known elsewhere. North American ring-tailed cat bears include 'ring-tailed cats' and 'cat squirrels', both mammals. The name North American ring-tailed cat bear comes from Nahuatl," which literally means "mid-mountain lion."
12, the most incredible mammals --- people
Did you know that from the point of view of biological evolution, humans are also mammals? But man is a very special kind of mammal, the human brain is surprisingly large, the average animal walks on four legs, but man walks upright on two legs. Not only that, but humans also have complex languages and words to communicate with each other, and animals can't speak.
Human beauty
@Dream Moke hopes that the most incredible mammals can protect nature and protect the only earth suitable for our survival!
