10 animals with very high life expectancy
As a result of the development of medicine, society and science, our life expectancy is growing every day. More and more people live to 100 years and more than ever before. Diseases that were once fatal, are now nothing more than a nuisance, and with the advent of new technologies, many people hope that they will be able to prolong his life, or perhaps even find a way to live forever in the form of a computer. But while we think to live to 90 years, it's great, some members of the animal kingdom are laughing in our faces. Below are ten animals on whose birthday cake is not enough room for the candle.
10. Sea bass (Rougheye Rockfish)
Despite the fact that the redfish (Sebastes aleutianus) is considered one of the most long-lived marine creatures on this list, he is only the tenth place. they usually live at depths of 170 - 670 meters underwater in the Pacific Ocean. Along the lower edge of the eye they can be up to ten spikes. This fish grows very slowly, it is very late mature and can live up to 200 years, with most adult specimens were found 205 years.
9. The red sea urchin (Red Sea Urchin)
Red sea urchin (Strongylocentrotus franciscanus) exists on our planet for 450 million years, and is the largest of all sea urchins. It can reach 25 centimeters in diameter. Usually they remain at the same place, so they are covered with protective spikes. However, sometimes they are grouped and scouring (or rather crawling extremely slowly) in search of food. Though they do not often live up to 30 years if he is still fails, then they can live more than 200 years. 8. The Bowhead Whale (Bowhead Whale)
Some scientists believe that bowhead whales may be the oldest living mammals on Earth. It is believed that one whale named Bada (Bada) lived to be 211 years old, but maybe he really was not less than 245 years. Although the majority of bowhead whale dies at the age of 20 to 60 years, 4 more found Greenland whales were close in age to the Bud - according to the scientists, they were 91, 135 years, 159 years and 172 years. In these pillars 7 collectively found harpoon whose age is not less than a century.
7. Koi (Koi Fish)
The average age of koi carp does not exceed 50 years, which in itself is not bad. But this is not even close enough to get into this list. However, carp koi named Hanako, who died in 1977, was much more venerable age of 226 years, that is, he was born as early as 1751. This means that the koi carp born before Benjamin Franklin discovered electricity, and before anyone knew that mammoths had never existed. This means that he lived at the time of the signing of the Declaration of Independence, during the French Revolution, survived two world wars, and so on. Its age was determined by counting the rings on its scales, as well as in determining the age of the tree.
6. Pogonophora (Vestimentiferan Tubeworms)
Pogonophores (Lamellibrachia luymesi) is sessile creatures, which means that they are carried out on one and the same place all my adult life. This particular kind of rift dwells mainly in the northern Gulf of Mexico. They live at a depth of 762 meters under the water in the cold deep water creeks. Pogonophores maintain a symbiotic relationship with sulphide-oxidizing bacteria, which are their only source of food. Pogonophores grow to three meters in length and can live for a thousand species groups. Given the fact that they grow extremely slowly, they can live up to 250 years. 5. The European pearl mussel (Freshwater Pearl Mussel)
According to estimates about 90 percent of the population of the European pearl mussel (Margaritifera Margaritifera) lives around Scandinavia. They are considered very hardy creatures that can adapt to changes in their environment quite easily. They are not a problem of climate change, as well as geological, physical, biological or chemical changes. However, despite that their population is constantly decreasing. Those individuals who survive are the most powerful and most likely experienced more than one change of ecosystems, such as the age of the animals is more than 250 years, making it possibly the oldest existing in Europe.
4. Tortoises (Tortoise)
Tortoises (Testudinidae) are famous for the fact that they can live a very long time. On average, a healthy turtle can live up to 150 years, but still, of course, depends on the type of turtle. The oldest turtle known to science have lived much longer than 150 years. Advaita (Adwaita) was a pet of British general Robert Clive (Robert Clive) before she came to the zoo in Calcutta, where she spent the rest of his life 130 years.
Impressive already only that at the time of her death, the zoo did not work, none of those who worked in it, when it was only brought. The turtle died due to cracks formed in its shell. After her death, the scientists conducted radiocarbon analysis of shell and found that her age was 250 years old, although some sources indicate 255 years, and the other 257 years.
3. Ocean Venus (Ocean Quahog)
Oceanic Venus is a type of shellfish that live mainly around the coast of Scotland. As might be expected, they move little, buried in sand or silt, and use their gills to filter food and oxygen from water. In order to avoid being eaten, they bury themselves deep in the sea floor, and live there for long periods of time without the need for oxygen or food. Over the past few decades, ocean trawlers led to the fact that their population has declined by about 50 percent, as they are killed and more on what damaged their shells, making them vulnerable to predators. As a result, all the smaller amount of oceanic Venus live to old age. These molluscs can live up to 400 years old and the oldest discovered specimen was 500 years old.
2. Antarctic sponge (Antarctic Sponge)
Many people do not even realize that sponges are actually animals (but if they were not, there would be SpongeBob, is not it?). Naturally, the sponge is not very mobile creatures, and some of them are moving less than 1 millimeter per day, so it is not surprising that they grow very, very slowly, like many other animals from this list. It measured their height gives them longevity. In the world there are between five and ten thousand species of sponges, and most of them live from 3 months to 20 years. However, Antarctic sponges live much longer, and one of the scientists found samples had a long life, namely 1550 years.
1. Jellyfish (Jellyfish)
Most likely, this option will not surprise many people, because in the last few years of their extraordinary capabilities became more known. Kind of jellyfish called Turritopsis nutricula does not have any particular appearance. Newborn length is 1 millimeter, and they are born with eight tentacles, while in adults has feelers 90 and their body length is 4, 5 millimeters. These small jellyfish were originally native to the Caribbean, but now they can be found all over the world. However, things are not as good as it might seem at first glance, because they can grow and multiply. What makes them unique not only among the jellyfish, but also among all the living beings that they can return to adolescence. These jellyfish are born and grow up like any other animal, but when they reach a certain age, they can go back to the polyp stage and begin to grow again. In human terms it would be about as if the 50-year-old man returned to the baby's condition. This means that these jellyfish are potentially immortal.
