Life expectancy of different animals: features and interesting facts

What is the life expectancy of different animals? What makes some representatives of the fauna able to exist over the centuries? What is the secret longevity of individual animals? All this will be discussed in our material.

How many dogs and cats live?

life expectancy of various animals

Dogs and cats are the most popular pets. Therefore, it is worth paying attention to these creatures, starting a conversation about how long the life of different animals is.

So, how are things with dogs? Each breed here has a different lifespan. For example, dogs such as bulldogs and Irish wolfhounds live an average of only 6-7 years. Otherwise things are with terriers, dachshunds, poodles. Their life expectancy is about 14 years. It is worth noting that you do not need to take the average for the maximum possible age.As practice shows, with proper care and maintenance of a pet's health, some four-legged human friends can live up to 20 years or more.

Providing information about the life expectancy of different animals, it is worth saying a few words about cats. For these pets, one of the determining factors that affects longevity is the way of existence. It is a question of whether the cat is left to itself on the street or is under the care of the owner at home. Outdoors, these animals die at the age of 4-5 years. This is often the result of injuries sustained in the struggle for survival, the lack of high-quality food, as well as all sorts of diseases. In turn, domestic cats, which are surrounded by the care of the owner, live much longer - from 12 to 18 years.

Bowhead whales

According to biologists, these huge creatures belong to the category of true centenarians among mammals. At one time, observations were made of the bowhead whale, known by the name of Bud, who died at the age of about 245 years. This case is an exception. Since the majority of the species live to a maximum of 60 years.

However, scientists have repeatedly recorded other similar cases. Researchers observed several other bowhead whales, whose age was close to a record high and ranged from 91 to 172 years. Harpoon tips with prescription of at least a century have been removed from the bodies of these animals.

Tortoises

We continue our conversation about the life expectancy of different species of animals. The glory of these champions here are turtles. As shown by the results of the study of this issue, on average, these creatures die at the age of about 150 years. Naturally, much also depends on the conditions of existence.

The oldest turtle known to biologists is an animal named Advaita. The latter was kept by the English military Robert Clive as a pet. After the death of the owner, the turtle was in the zoo of the city of Calcutta. Surprisingly, Advaita managed to live another 130 years here. The cause of the death of the animal was the formation of cracks in the shell. After the death of the turtle, scientists decided to establish its real age. To do this, the researchers used the method of radiocarbon analysis of tissues.The test results showed that at the time of death the age of the Advaita tortoise was a record 250 years with possible minor deviations in indicators.

Ocean venus

life expectancy of different types of animals

This marine mollusk leads a sedentary lifestyle, obtaining all the nutrients and oxygen that are necessary for its existence due to the filtration of water. In order not to become a victim of predators, such animals are immersed deep in the sand and remain there for a long time without the need for food. According to researchers, the Ocean Venus is capable of surviving to an unimaginable 400-500 years.

Antarctic Sponge

We continue the conversation about the life expectancy of different species of animals. The plant is exactly what the Antarctic sponge may seem at first glance. However, it is not. Sponges are animals, but almost motionless. Some of them move from one place to another in a few millimeters during the day. Such creatures are distinguished by extremely measured growth, owing to their longevity.

At the moment, biologists have registered about 50,000 species of sponges. The bulk of creatures in this category live only a few decades.However, an exception to the “rules” is the Antarctic sponge. Scientists managed to find samples that were older than one and a half thousand years.

Jellyfish

life expectancy of different types of animals and plants

The average life expectancy of different animals is not so great. As for creatures such as jellyfish, they are absolutely not “concerned” with the issue of aging. Recent observations of these animals shed light on fantastic abilities. So, jellyfish, which belong to the species Turritopsis nutricula, are among the most miniature creatures on the planet, whose size reaches only about 4 millimeters. They are unique because they have the ability to return to the "infant" age. Such jellyfish develop like any other representative of the fauna. However, upon reaching maturity, they can go back to the polyp stage, after which the maturation process is restarted. According to special studies, jellyfish Turritopsis nutricula potentially have immortality.

Life expectancy of various animals: a table

For how long can there be individual representatives of the fauna? I would like to bring to your attention a table in which the average and maximum life expectancy of different animals is marked:

Finally

So we looked at the life expectancy of different animals. As can be seen, among the representatives of the fauna there are both true long-livers, and creatures that nature has allotted not so much time. Despite the calculations of scientists regarding the average and maximum life expectancy of certain species, exceptional cases are often noted.
