Shark Astonishes Scientists by Regenerating Torn Fin in Under a Year

A silky shark with a severely torn dorsal fin, first spotted off the coast of Florida in 2022, has been observed nearly a year later with the fin almost fully regenerated. This remarkable recovery, documented by underwater photographer Josh Schellenberg, showcases the shark's ability to heal and possibly regenerate tissue, a phenomenon that has been rarely documented in sharks. Researchers are intrigued by the healing process, which could involve new tissue growth or scar tissue fusion, and the incident provides valuable insights into the regenerative abilities of marine creatures like the silky shark. The study detailing this observation has been published in the Journal of Marine Sciences.
