First video of great white shark in Mediterranean offers new conservation data
Volunteers from Ghost Diving and Healthy Seas capture unprecedented footage of the critically endangered apex predator, providing researchers with vital behavioural insights.
Volunteers from the marine conservation organisations Ghost Diving and Healthy Seas have recorded the first-ever video footage of a great white shark in the Mediterranean Sea. The encounter occurred during a dive in the Strait of Sicily and features a large adult male specimen of Carcharodon carcharias. The footage, captured by diver Derk Remmers, provides a rare live observation of the species in its native habitat, offering data that has previously been difficult to obtain.
Great white sharks have inhabited the Mediterranean for millions of years, yet the population is now classified as critically endangered. While the species is listed as vulnerable on the International Union for Conservation of Nature Red List globally, the Mediterranean cohort faces severe threats from accidental capture in fishing operations, illegal fishing, habitat loss, and the decline of natural prey. Sightings have become increasingly rare, making this documentation a significant scientific event.
Carlo Cattano, a researcher at the Stazione Zoologica Anton Dohrn, highlighted the importance of the sighting. He noted that much of the existing knowledge about Mediterranean great whites has been derived from dead specimens caught during fishing operations. Live observations are therefore crucial for accurately understanding the distribution, habits, and behaviour of the species.
The footage validates the ecological importance of the Strait of Sicily area. As apex predators, great white sharks play a critical role in maintaining marine ecosystem balance by regulating prey populations. The sighting serves as a reminder of the fragility of these ecosystems and the need for strengthened conservation efforts to protect the remaining population.
Although the species has a formidable reputation, attacks on humans are very uncommon. The encounter, which Remmers described as thrilling, underscores the value of continued monitoring. Researchers state that every documented sighting provides valuable information for developing conservation strategies for this critically endangered species.
