A rare sighting of a Great White Shark measuring about 4 meters has been captured on video off the coasts of Porquerolles and Port-Cros. Nicolas Ziani, shark expert, confirmed the species and is calling for public sightings to aid scientific research. The shark, observed by a yachtsman earlier this month, is believed to be a young individual. Great White Sharks are considered critically endangered, and experts note that their presence could indicate healthier marine ecosystems. The Groupe Phocéen d’Étude des Requins is set to release updated sightings data in December.
