An encounter with a great white shark is undoubtedly a “thrilling” experience, considered especially rare in the waters of the Mediterranean Sea. The latest sighting, which has attracted media attention and made headlines around the world, occurred during a dive in the Strait of Sicily carried out by volunteers from Ghost Diving and Healthy Seas, organizations dedicated to protecting marine ecosystems.

The encounter was documented by diver Derk Remmers, who told the BBC that he struggled to switch on his camera because of the excitement. The footage—the first ever recorded of a great white shark in its Mediterranean Sea habitat—shows a huge adult male specimen of Carcharodon carcharias, a native species that is now considered critically endangered.

Carcharodon carcharias, commonly known as the great white shark, belongs to the Lamnidae family and is one of the largest predatory fish in existence. It can exceed 6 meters (20 feet) in length and weigh more than 2 tons. It feeds primarily on fish, including rays and other sharks, though adult individuals may also prey on marine mammals like seals and dolphins. Equipped with an extremely keen sense of smell and excellent swimming abilities, the great white shark is considered one of the most efficient apex predators in the food chain.

Despite its reputation, attacks on humans are very uncommon. And the species is increasingly threatened by human activities, particularly accidental capture in fishing operations, illegal fishing, habitat loss, and the decline of its natural prey. For this reason, Carcharodon carcharias is classified as vulnerable on the International Union for Conservation of Nature Red List, while the Mediterranean population is considered the most precarious and is classified as critically endangered.

Every documented sighting of a great white shark in the Mediterranean therefore represents a valuable opportunity, as it provides useful information for scientific research and conservation strategies for the species in a sea where its presence is now extremely rare. At the same time, this latest encounter can be interpreted as an encouraging sign for marine biodiversity and a reminder of the importance of continuing and strengthening conservation efforts in marine ecosystems, which are considered among the most fragile in the world.
