A rare discovery off the coast of Spain is giving scientists hope that great white sharks have a good shot of a comeback in the Mediterranean Sea. Why do they think this? Well, in 2023, local fishermen accidentally caught a juvenile great white shark. This rare catch sparked huge debates over what’s happened to the great white population. Researchers are now reviewing more than 160 years of historical records. And their findings suggest that while sightings are extremely rare, great white sharks have never completely disappeared from the region.
What is most exciting about this catch is the shark’s age. Finding a juvenile means that somewhere the sharks are doing well enough that they are breeding. Scientists often refer to the Mediterranean’s great whites as a “ghost population” because they are so rarely seen. As vulnerable apex predators, they play a critical role in maintaining healthy marine ecosystems. Researchers hope continued monitoring and new tracking technologies will help uncover more about these elusive sharks and ensure their long-term conservation.
Scientists describe the Mediterranean population as a “ghost” population. Encounters are so rare that they don’t seem to exist. But lurking somewhere in those waters must be a thriving shiver of them that are still doing well enough to live long enough to reproduce.
Currently listed as Vulnerable on the International Union for Conservation of Nature (IUCN) Red List, they are considered to be at risk of extinction. Great white shark populations are believed to be declining, increasing the importance of understanding where they still occur and how they use their habitat.
Why are Shark Populations Declining?
Great Whites became endangered for a number of reasons. One of them of course is humans hunting them for trophies, teeth and fins. We’ve also impacted their feeding grounds so that food is much harder to come by for them. They also have very slow reproductive habits. A Great White won’t have any offspring until they reach 15 years of age. Then of course more man made disaster as we dump toxins and garbage into the sea. And lastly Killer Whales are driving them out of their homes making it hard to stay in one place too long. While we think of the Great White as one of the top apex predators, truth is they’re not at the tippy top of the food chain. Orca trumps Great White.
