Ningxia found 1 3 meters over 50 years old wild salamander, how long is the life span of the salaman

The lifespan of the salamander is relatively long, and usually the lifespan of the salamander in nature can reach hundreds of years. <>

Recently, a giant salamander was found in the Liupan Mountain National Reserve in Ningxia, the total length of this wild salamander reached meters, and the weight was about 40 catties. In fact, wild salamanders are relatively difficult to find, mainly because this wild animal rarely goes out, and most of the time it inhabits the caves of streams. On the same day, a worker who treated the river found this giant salamander at the No. 6 dam, and later according to the staff's measurements, it was found that the width of the skull of this large salamander reached meters, and the age of this salamander is expected to be more than 50 years.

In fact, like this wild large salamander, itself is a national second-class key protected wild animal, so after the staff finished the surveying work, they took this large salamander directly to the upper stream of the Jing River to be released, because the fish and shrimp in this stream are more abundant, and it will be more convenient for this salamander to hunt if it lives here. <>

The reason why the baby fish is called the baby fish is actually because the sound of this fish is very special, like a baby crying. But in fact, the salamander does not belong to the fish, strictly speaking, this species should be an amphibian inhabiting freshwater, and the salamander is actually the largest amphibian, most of the salamander body length is about one meter, and the longest can reach about two meters. The normal weight of the baby fish is basically about 20 kilograms, and the largest can reach about 50 kilograms.

Now the wild large salamander is basically a critically endangered species, because this large salamander has very high requirements for water quality, once the water quality is polluted, it is difficult for them to move, after all, the migration ability of this species is indeed relatively poor.

The maximum lifespan of salamanders can reach 80 100 years, but the average salamander has a lifespan of only 50 60 years.

The salamander has the longest lifespan among amphibians, and can live up to 130 years in captivity. In the past, due to the large number of people who did not know how to protect wild animals, they were ruthlessly overfished, resulting in serious damage to the resources of many areas, and some areas were on the verge of extinction. Now, China has stipulated that the salamander must be protected.

The life span of the salamander is relatively long, the long one can live to be more than 130 years old, and it can survive for hundreds of years.

Ningxia found rice over 50 years old wild baby fish, baby fish life expectancy is generally 50 to 60 years, it is said that can survive up to 80 to 100 years, it is reported that in Zhangjiajie will be the largest baby fish in China "Ben Ben" declaration Guinness World Records, has been nearly 130 years old, body length of nearly 2 meters, is the largest baby fish found in China so far. The Chinese giant salamander is an amphibian that lives in freshwater. It is a precious wild animal that is a specialty of China, commonly known as "baby fish".

It takes 20 years for a 20-pound baby fish. Generally, it grows pounds a year.

"Baby fish" is the largest of the amphibians, with a total length of 1 meter or more, and the heaviest can weigh more than 100 catties, and the appearance is a bit similar to a lizard, but it is fatter and flatter in comparison. Recently, scientists have studied that baby fish use gills to breathe when they are young, and they use their lungs to breathe when they grow up.

In the Xia Dynasty document "Overseas Western Longitude", the salamander is called the arowana, and the salamander has a longer lifespan among amphibians, which can survive for hundreds of years.

Remember to adopt it.

50-60 years, some salamanders can live for 100-120 years, when long-lived aquatic animals. Seek adoption.

200-year-old because of Zhangjiajie, there is a 200-year-old baby fish.
