Your animals may outlive you

1. The parrot

You might be skeptical when you see "parrot".My family also had a parrot ah, did not think it longevity ah. Indeed, when it comes to the life span of parrots, it has to be realized that there are many kinds of parrots, and the life span of different kinds of parrots varies greatly, and the length of their life span is related to their body size. Our common budgie, peony parrot belongs to the small parrot, their life is more than 8 years, the highest can reach 25 years, if raised this kind of lovely small parrot, you should cherish and it get along with the time. Medium-sized parrots, like the jumbo Hairet, outlive puppies and cats, typically living for more than 20 years and up to their 40s. If you are a large parrot like the wise and studious macaw, its life span is as short as 50 years, the longevity can live to 80 or 90 years. It's a very long-lived parrot. According to British media, the world's oldest parrot was an Amazon parrot named Jamie, who was born on December 3, 1870, and died on November 5, 1975 at the age of 104. Why do parrots live longer than other birds? The scientists compared the genomes of parrots with those of 26 other bird species. They showed that parrots carry mutations in genes that support unusual longevity in small animals. They maintain telomerase activity, an enzyme that plays a role in DNA damage repair, cell proliferation, cancer and immune regulation, and antioxidant activity. If telomerase activity continues to increase, parrots live longer.

2. The tortoise

When you think of long-lived animals, the first one that comes to mind is probably the tortoise. It is indeed one of the longest-living members of the reptile family. When it comes to living long, it comes to the tortoises that are found in Africa, America, Asia, and some of the islands in Oceania. It is named "tortoise" because of its thick and strong legs. It is the "giant" of tortoises, among which the Galapagos tortoise can reach 1.8 meters in length. When it comes to the oldest tortoises, Geologist Jun has found different answers. One of them, Advita, an Aldabra tortoise, was born in 1750, during the reign of Emperor Qianlong of the Qing Dynasty. He died at the Kolkata Zoo in 2006. He lived to be 256 years old and had three generations of keepers in between. During his more than 100 years at the zoo, he did not like exercise, nor was he fussy about food. He particularly liked fruit. When the weather is hot, he likes to take a bath in the pool to cool himself off. Why do turtles live so long? Experts differ, say it contains special immune globulin inside the body, can resist all kinds of diseases; Also said that it has a large number of sod (superoxide dismutase), can effectively eliminate "oxygen free radicals" delay aging; Oh, and it's also said that it moves slowly, which makes its metabolism slow, which keeps it young forever. This last one has you wondering, is it true that life is static?

3. The clams

What? Clams are long-lived animals, too? Yeah, we just eat most of them before they get old. In 2006, scientists from Bangor University's School of Marine Sciences collected a large number of living Arctic clams from the Icelandic seabed in the northern Atlantic Ocean. They followed a sample collection procedure and froze the clams to bring them back to the laboratory for analysis, but the clams died in transit. When the researchers looked at the clams under a microscope in the lab to check their age, one clam turned out to be 405 years old. When scientists re-examined the shell of the Arctic clam, they found it was 507 years old because of an earlier miscalculation. Why does this Arctic clam live so long? Experts say the clam itself is long-lived, and Arctic clams over 100 years old have been found before. The secret to its longevity lies in the slow metabolism of its cells, which has not yet been determined, but probably has something to do with the cold environment in which it lives. The bowhead Whale When it comes to the long-lived animals that live in the Arctic sea, in addition to the Arctic clam, there is a much larger behemoth, and that is the bowhead whale. Among whales, bowhead whales are third in size after blue whales and fin whales. Adults can grow to 17 to 20 meters, and females are slightly larger than males. He looks like a fat, flexible man, but he doesn't swim very fast. The five existing populations of bowhead whales are found in the Bering-Chukchi Beaufort Sea region, in Greenland's Bavin Bay, in Canada's Hudson Bay, in Russia's Sea of Okhotsk, and off Svalbard. They are uniquely adapted to the cold of the Arctic. For example, in order to breathe through polar sea ice, they have huge heads, which can take up 30 to 40 percent of their body length.
