The longest lived mammal, the longest lived mammal in the world is

The longest-lived mammal in the world is the bowhead whale.

The bowhead whale, named for its large and distinctive bow-shaped head, is a marine mammal belonging to the order Cetaceans, which can reach up to 21 meters in length (females are larger than males) and have a very heavy body.

It had an estimated lifespan of about 60 70 years, which is similar to that of other cetaceans. However, in 1999, the discovery of old ivory spear tips in whales triggered the study of the structure of whale eyes, so it can be reliably concluded that at least some individuals can live to be 150 200 years old.

Another study showed that female whales were still fertile up to 90 years old. Due to their long lifespan, females may also have the phenomenon of menopause.

The habits of bowhead whales

Bowhead whales swim slowly and are usually solitary or form small groups of up to six. In general, float on the surface of the sea for 1 to 3 minutes and jet 4 to 6 times. It is possible to dive to depths of more than 200 meters and stay in the water for up to 40 minutes, but is not an expert diver.

Bowhead whales usually do it alone, typically by jumping vertically out of the water, with the second half of the body usually remaining in the water and finally entering the water sideways. Most of the jumping waves occur during the spring migration.

The life span of mammals in the world: 5 years for porcupines, 19 years for seals, 10 years for slow loris, year of wild boars, 11 years for otters, 21 years for leopards, years of yellow sheep, 22 years for yaks, 12 years for bats, years of gibbons, 12-14 years of camels, years of marmots, years of orangutans, years of squirrels, years of wild horses, 15 years of martenes, 28 years of giraffes, years of great civets, 29 years of macaques, years of antelope, 30 years of lions, years of wolves, 34 years of bears, years of sambar, 40 years of chimpanzees, 19 years of red deer, year of hippos, 19 years of tigers, 47 years of rhinoceros, 19 years of argali, 69 years of elephants.

From the above preliminary statistics, it can be seen that elephants, rhinoceros, hippos, bears, lions, macaques, wild horses, etc., have relatively long lifespans, and most of them are giant animals. Some people believe that huge animals have strong defenses, strong vitality, and are not susceptible to natural predators. At the same time, it takes a long time to complete the various stages of development in life, for example, the young elephant takes 20 months to breastfeed, and it takes 30 years to reach real maturity, and its maximum lifespan can even reach 120 years.

In addition, it has been assumed that large animals not only help protect against the cold, but also consume relatively less heat than smaller animals in their lifetime, because the larger the size, the smaller the relative area. Incidentally, all animals tend to live longer in captivity than in nature. Because the living conditions in captivity are more favorable, and there are no predators and diseases in nature, at least the chances of suffering or getting sick are much less.

From 100,000 whys).

Most elephants live to be between sixty and seventy years old.

2.However, because wild places and captivity are different, there are also differences in the length of life, and the former has a shorter lifespan.

3.It is recorded that the long-lived elephants of the Golapagos lived to be between 180 and 200 years old.

Although human beings have always been obsessed with longevity, our life of about 100 years is obviously not enough in the real long-lived biological community. Some of them can even transcend history in their life cycles, from ancient times to the present, and some can live for half a century without saying a word.

Polar bears are the longest-lived mammals. Polar bears, also known as white bears, are a species of marine bears that are mainly found in the Arctic region. They can live up to 30 years and are generally about 500 kilograms long and weigh about 500 kilograms when they reach adulthood.

And the reason why they can live so long is mainly because they live in a special environment, there are almost no natural predators, and the genetic mutations in their bodies can help them better adapt to the extreme environment.

Polar bears are considered a threatened species. Human destruction of their habitats, climate change and overhunting all pose a threat to the survival of polar bears. However, because polar bears are carnivores and accumulate high levels of toxic substances in their bodies, overhunting by humans has been prohibited.

In addition, many countries are taking steps to protect their habitat to help protect this rare species.

It is worth mentioning that in addition to polar bears, there are also some animals that can live very long, such as elephant turtles, whales and sharks. The reason why these animals can live for a long time, or for hundreds of years, is also due to their unique species characteristics, as well as factors such as the environment and habits in which they live. This phenomenon provides us with an opportunity to better understand the animal world, so as to better protect them and build a more harmonious ecological environment.

The longest-lived mammal is the elephant.

Aside from humans, the longest-lived mammalian on land is the elephant, with an average lifespan of around 69 years. Elephants are the world's largest land-dwelling social mammals and generally operate in families. The main features of the elephant are its soft, muscular snout, fan-sized ears, large body and a pair of very intimidating tusks.

The trunk is almost the same length as the elephant's body, and it is cylindrical in shape, curved freely and very flexible. The trunk is almost entirely made of muscle, with nostril openings at the end and finger-like protrusions at the tip of the nose, which can pick up objects weighing up to 1 tonne as well as small objects.

Elephant habits

The herd is generally led by the female elephant, and the daily activity time, the movement route of the Min Na key, the place of eating, the habitat and so on are all commanded by the female elephant, while the main responsibility of the male elephant is to protect the family. Elephants mainly feed on young leaves, wild fruits, wild grasses, vegetables, young bamboos and other plants, and eat a lot of food, needing to eat more than 250 kilograms per day, and the life span is generally about 80 years.

Elephants can communicate through infrasound waves, and when they arrive, they travel along the soles of the feet through the bones to the elephant's inner ears, which are then amplified by the fat on the elephant's face. If there is no interference during propagation, it can generally travel about 11 kilometers. If the medium is uneven due to airflow sensitization on the way, it can only propagate for 4 kilometers.

In this case, the herd of elephants, if they need to communicate, stomp their feet together, producing a powerful roar.

1. In mammals.

, the longest-lived animal is the elephant.

It is said to live to be sixty to seventy years old. Of course, there is a difference between wild and captive-bred animals, and the former has a shorter lifespan. It is recorded that the long-lived elephants of the Golapagos Islands lived between 180 and 200 years.

The world's longest-lived animal, a large tortoise named Harriet, celebrated its 175th birthday on the 14th and also received a pink hibiscus flower.

Tortoise, born in 1830, weighs 150 kg.

3. It is a Guinness World Record.

Certified oldest living turtle and shelled reptile.

Steve Owen, an Australian animal conservationist, said: "It's certainly the longest-lived animal in the world. I think it will definitely live to be 200 years old. "Legend has it that it was once Darwin.

of pets. Darwin returned to England from his round-the-world expedition to "Beagle"**, bringing back several baby turtles. These baby turtles were both his pets and the subjects of his research, including Harriet, but historians have doubts about this claim.

5. For more than a century, it was mistaken for a male tortoise and named Harry. It wasn't until the 50s that Harriet was able to identify herself and become a female turtle named Harriet.
