Shark regrows fin after it was cut by humans | Live Science
Black didn’t expect to see the shark again, as the injury was extensive and she could no longer track the animal. But, remarkably, almost a year later, the shark returned to the same waters and was photographed with a rejuvenated albeit slightly stumpy fin.
“It was shocking!” Black said. “My first reaction was relief that the shark was still alive, as that was a traumatic wound that could affect his swimming ability or create a significant infection.”
This is the first time researchers have observed a silky shark regrowing its dorsal fin and only the second recorded case of dorsal fin regeneration in any shark, according to the study, published Dec. 14 in the Journal of Marine Sciences.
Well, good, I think.
