Critically Endangered Mako Shark Tagged for the First Time in the Mediterranean

In a groundbreaking achievement, researchers successfully tagged a critically endangered shortfin mako shark in the Mediterranean for the first time. Brendan Shea, a Ph.D. student at Virginia Tech, emphasized the importance of this milestone, stating, “The tag provides valuable information about the shark’s movements, helping us understand how to better conserve the population.”Innovative Tagging TechnologyThe team utilized a pop-off archival tag, a cutting-edge device that records data on water temperature, depth, and light levels.

This information allows researchers to track the shark’s location and behavior. The tag detaches after a set period or if the shark dives deeper than 1,800 meters, transmitting the data back via satellite.“These tags reveal where these animals travel, making conservation efforts more precise,” Shea explained.

While more tagging is needed, this initiative marks a promising start.Collaborative Research EffortThe tagging was part of the White Shark Chase initiative, led by Francesco Ferretti at Virginia Tech. The study involved experts from institutions including Virginia Tech, Stanford University, Oregon State University, and international collaborators.

The research was funded by organizations such as The Explorers Club, Discovery Channel, Sharkproject, and the Bertarelli Foundation.Key Insights Into Shark ConservationThe young mako shark, estimated to be 1–2 years old, traveled over 750 miles in just 54 days. This finding underscores the need for broader conservation strategies beyond protecting nursery areas.“Sharks are essential for maintaining healthy oceans,” Shea said. “Understanding their movements and roles in the ecosystem benefits marine biodiversity and human activities alike.”By uncovering the depths and habitats these sharks occupy, the research provides crucial data to guide conservation policies.
