Volunteer divers have recorded what researchers believe is the first footage of a great white shark filmed underwater in the Mediterranean, captured during a ghost net removal dive near a shipwreck in the Strait of Sicily.

Derk Remmers, a technical diver with Ghost Diving, was about 40 meters (131 feet) below the surface between Sicily and Tunisia when the shark appeared. He filmed the encounter. The footage and photographs were released on June 8 to mark World Oceans Day.

Remmers said that the odds of meeting such an animal underwater are far lower than winning the lottery, and that his hands were shaking as he filmed.

The shark circled the group, then turned and moved back toward the divers. Remmers said that its behavior appeared calm and curious, not aggressive. When the team released air from their regulators, the shark picked up speed and disappeared from view.

First great white shark sighting in the Mediterranean stuns researchers

Marine biologists who reviewed the footage called the sighting rare and scientifically significant.

Dr. Carlo Cattano, a researcher at the Sicily Marine Centre of the Stazione Zoologica Anton Dohrn, said that most knowledge of great white sharks in the region has come from dead animals caught accidentally in fishing nets, and that direct observations help researchers better understand the species.

He said that prior research had already identified the area as a key location for threatened species and that this sighting reinforces its conservation value. Researchers cautioned that broader conclusions would require further study.

The mission was organized by the Healthy Seas Foundation, along with Ghost Diving and the Society for the Documentation of Submerged Sites. The wreck’s location is being kept confidential.

Ghost nets, fishing gear lost or abandoned at sea, continue killing marine life long after leaving a vessel. Previous dives at the site documented loggerhead sea turtles and large fish species caught in the gear.

Shipwrecks attract marine life, and when ghost nets settle on them, those structures become underwater traps.

Ghost nets turn shipwreck ecosystems into ongoing ocean traps

Veronika Mikos, director of Healthy Seas, said that the sighting is a reminder of how much marine life still exists in offshore Mediterranean waters and how much is at risk from discarded gear and overfishing.

Remmers said that between 1% and 10% of all fishing gear worldwide is lost each year, possibly adding more than 500,000 metric tons of abandoned nets to the ocean annually.

He said that the shark’s presence near the wreck signals an abundance of prey, and that those same animals face entanglement risk. Volunteer cleanups alone cannot resolve the problem, he said, and stronger action against industrial and illegal fishing is needed.

The mission also included environmental DNA sampling and underwater monitoring. Healthy Seas said that it plans to release additional footage and scientific material in the coming weeks.

In the mountain villages of Guatemala’s Western Highlands, farmers are combining ancient Maya knowledge with modern sustainable farming techniques to protect their crops from pests and disease. Smallholders are creating homemade biopesticides using plants with strong smells and flavors to deter pests on their family plots. This is helping to cut back on the use of increasingly expensive agrochemicals, many of which have been labeled as dangerous to human health and linked to soil degradation. About 60 Guatemalan communities in the Western Highland departments of Sololá and Huehuetenango, as well as Chiquimula in the east, are working to revive these traditional techniques with support from the international development organization World Neighbors. Their focus is to restore and strengthen traditional knowledge, combining it with agroecological practices that help families produce surplus food they can sell to boost household incomes. “Traditional farming techniques are becoming popular because they are simple practices to apply, use local resources, and have proven to be effective,” Dayani Roche, a program associate at World Neighbors, told Mongabay via email. Rather than a single ancient recipe, farmers are using “a living combination of ancestral knowledge, local experimentation and more recent agroecological practices,” he said, which are “safer for families, soil, water and biodiversity than many chemical alternatives.” The Maya civilization, which once stretched across modern-day Central America, had a rich history of farming dating back to 2000 B.C.E. Its most celebrated agriculture system is the milpa, a form of intercropping that involves a mix of maize, beans and…This article was originally published on Mongabay
