The lifespan of Kulakant was thought to be about 20 years until now, but accordingly BBC, New estimates suggest that this fish is a century in the ocean along with sharks.
Researchers have used growth rings on fish scales, which, according to marine biologist Gelig Mahe, are from the French marine company Eframer, and the lead author of this week’s study is the current biologist – “Studying Tree Rings”.
Now, French researchers believe that these fish develop at a slower rate and reproduce only at the end of middle age, at the age of 55, when they reach sexual maturity.
Based on the fossil record, it is believed that these fish disappeared during the extinction of the dinosaurs at the end of the Cretaceous. However, in 1938 the fish was found alive off the east coast of South Africa.
Slow-growing fish produce few offspring, which are particularly vulnerable to destructive pressures such as climate change and overfishing. Bruno Hernandez of the University of Montpellier in France says knowing the biography of this fish will help impose even stronger safety and security measures.
“The most important framework for conservation measures is being able to estimate organism statistics,” he explained to the BBC. “With this new information, we can better evaluate it.”
Two people were found off the east coast of Africa and another on the coast of Sulawesi, Indonesia. African people were classified as endangered, with only a few hundred samples remaining.
“Our results suggest thus [o celacanto] This may be even more threatening than expected due to its bizarre biography. As a result, this new information on the biology and biography of the Kulacans is essential for the conservation and management of this species, “explains Golic Mahe.
Goyalkanth’s ancestors evolved 420 million years ago, escaping the catastrophe of asteroids destroying changing continents and dinosaurs, which can grow up to 1.8 meters and 200 pounds.
