Today, we carried out a focused marine survey at Liri Beach, South Pelion, at 4-meters depth, dedicated to the observation and documentation of the Common Stingray (Dasyatis pastinaca). This species is a familiar yet often overlooked inhabitant of Mediterranean coastal waters, and our aim is to better understand its local presence, behavior, and habitat preferences.

About the Common Stingray

The Common Stingray is a benthic species, usually resting on sandy or muddy seabeds, often partially buried and well camouflaged. It can grow up to 140 cm in length, with a disc-shaped body and a long whip-like tail that carries a venomous spine used for defense. Although generally non-aggressive, stingrays can inflict painful stings if disturbed, which makes observing them with care essential.

They feed mainly on bottom-dwelling invertebrates and small fish, playing an important ecological role in maintaining the balance of benthic communities. In Greece, they are considered relatively common, but systematic data on their abundance and seasonal movements are still limited.

The “mind gap” image serves as a powerful metaphor for the ethical challenges that lie beneath the surface of conservation surveillance. While the rise of advanced monitoring technologies has transformed the way we protect wildlife and ecosystems, it has also opened up difficult questions about privacy, consent, and the balance of power.

Essential Tools in Conservation Surveillance

Over the last two decades, several technologies have become indispensable to conservationists:
​
• Camera traps are used for tracking elusive or endangered species
• Drones help survey landscapes and monitor wildlife from above
• Acoustic sensors record everything from whale songs to the sound of chainsaws in a forest
• Satellite monitoring tracks deforestation, marine traffic, and illegal fishing

These tools provide non-invasive research opportunities, improve data accuracy, and enable stronger enforcement against poaching, logging, and other environmental crimes. They also generate real-time data for rapid responses and create compelling evidence that helps secure funding and public support.

Monitoring Targets

The technologies are used to monitor a wide range of conservation targets:
• Wildlife and ecosystems include tracking species, studying animal behavior, and assessing population trends
• Illegal activities include detecting deforestation, illegal logging, poaching, wildlife trafficking, and marine violations
• Human communities are often unintentionally monitored when drones and cameras capture local people’s daily lives, raising concerns about privacy and the risk of mission creep, where data might be used for policing beyond conservation

While the first two categories clearly align with conservation goals, the monitoring of human communities, whether intentional or incidental, introduces sensitive ethical issues about transparency, consent, and who controls the data.

Benefits of the Rise of Surveillance

The benefits of these technologies cannot be dismissed. They allow for less disruptive research, produce better ecological data, and enable quicker action in crises. In many cases, they are the difference between preventing species loss and watching biodiversity disappear. Some argue that the urgency of the biodiversity crisis outweighs concerns about privacy, making surveillance a necessary sacrifice for the greater good.

Bridging the Ethical Divide

The “mind gap” highlights the need for balance. Surveillance technologies can protect both nature and humanity if they are deployed with clear ethical guidelines. This means ensuring transparency, respecting community rights, and avoiding the misuse of data for purposes unrelated to conservation.

The rise of surveillance in conservation is not a simple story of tools and targets. It is a test of our ability to protect the planet while upholding the dignity and rights of all living beings. The tools are powerful, but the real challenge is how we choose to use them.

We have compiled a map of purple jellyfish (Pelagia noctiluca) records for August.

Most sightings, as expected, were concentrated in the North Evoikos Gulf and the Pagasitikos Gulf. These semi-enclosed gulfs tend to trap jellyfish populations, allowing them to remain for longer periods.

Although summer has ended for most, it is important to remember that a purple jellyfish outbreak can last up to four years. Monitoring continues throughout the winter, and next summer we are likely to see them again, potentially in new areas as well.

If you spot jellyfish of any species, we encourage you to take photos and upload them to iNaturalist (preferred) or share them in the Facebook group.

Citizen science is an essential tool for monitoring and keeping the public informed!

🙏 Thank you to all citizen scientists and observers contributing to the effort. Every sighting counts!
