Scott Cross, a biologist at Rutgers University, described an unusual freshwater fish in North America who can live for more than 120 years without getting older.
It is about the big mouth buffalo, which lives in the lakes and rivers in the United States and Canada. The biologist mentioned that some large -mouth buffalo populations have had no new generation for more than half a century. In addition, as they grow old, they continue to evolve.
These fish have an olive color scales with black copper spots. They can grow over 122 centimeters in length and sing 36 pounds, reports Noi.md with reference to.
The biologist reminded that scientists who studied the population of these fish noticed that most of them were born before the middle of the 20th century. Of the 52 individuals observed between 2018 and 2021, only one hatched after 1997.
The main feature of the buffalo with the big mouth is that it has no signs of aging. The biologist mentioned that in these fish the immune system does not weaken, stress does not increase and no cell degradation occurs.
