On a mission to clear harmful abandoned fishing gear from the Strait of Sicily, volunteer diver Derk Remmers had an unforgettable encounter with a rare great white shark — a reminder of the vibrant life that still thrives beneath Mediterranean waters.
- Volunteers remove dangerous ghost nets harming marine ecosystems.
- Great white shark sighting in the Mediterranean is extremely rare.
- Encounters emphasize vital importance of ocean conservation work.
What happened
Volunteers from the Healthy Seas initiative have spent countless hours diving in the Mediterranean Sea, specifically the Strait of Sicily, to remove ghost fishing gear – lost or abandoned nets that trap and kill marine life. In 2025, their efforts amounted to 140 diving days contributed by 550 divers focused on restoring these fragile underwater habitats.
During one of these dives, volunteer Derk Remmers experienced something extraordinary: a large great white shark appeared close enough that he struggled to steady his camera to capture the moment. Great whites are known to inhabit the Mediterranean but live sightings are extremely scarce, making this encounter notable for scientists and conservationists alike.
Why it feels good
The sighting brings hope and excitement, reminding us all that despite the many threats facing oceans, vibrant and important marine life still exists in these waters. It reinforces the value of dedication and teamwork among volunteers who work tirelessly to protect fragile ecosystems.
Experts emphasize that studying these rare encounters helps improve understanding of great white shark behavior and distribution. Protecting the shark’s habitat from human threats, like ghost gear and overfishing, is critical to the survival of this endangered species. Moments like this reveal the positive impact of conservation work and inspire continued efforts.
