Study published in Marine Science Journal Documented Regeneration of the dorsal fin of A Sharks silkThe scientific name Carcharinus falsiformis. This is just it The second case of fin regeneration recorded in any shark.

The shark had part of its fin Cut by humans In Jupiter, Florida (USA). The case occurred in June 2022. The researchers attached a tag to the dorsal fin of the silky shark to monitor its migration, but they noticed that an unknown person cut the tag off. The shark was left seriously injured.

About 20.8% of its fin was cut off. After a renewal period of approximately one year, 87% of the original size of the silky shark's dorsal fin has been restored. Researchers were able to follow up on the operation, as local diver, John Moore, found the injured animal and contacted scientists.

How did the renewal happen?

Study author Chelsea Black documented the animal's regeneration Through photos taken over a period of 332 days. The documents also showed that there was an approximate increase in 10.7% In the fin area, which indicates Tissue regeneration. By day 42, the initial wound had completely healed, the study says.

The researchers said this is the second recorded case of regeneration in sharks They still cannot say with certainty how this process occurs. Lions believe that the regenerating part of the fin is It consists mainly of scar tissuelike Live Science said.

However, researchers do not find it difficult to believe in this evolutionary mechanism in sharks, because… They are known for their ability to recover quickly. Research even shows that these animals They have immediate anti-inflammatory responses to injuries.

“There's a reason sharks evolved hundreds of millions of years ago and have survived multiple mass extinction events. This story proves how resilient they are,” Black summarized.
