Dr. Mauricio Hoyos and his encounter with a shark that reaffirms our conservation mission

Dr. Mauricio Hoyos, director of Pelagios Kakunjá, founder and board member of the Saving Our Sharks Foundation, He is one of the most renowned figures in the study of sharks internationally. His work has been key to understanding fundamental aspects of these species, such as their breeding grounds, reproduction, migration patterns, behavior, and habitat use. He is also known for his commitment to sharing his knowledge and training new generations of scientists and ocean conservationists.

During their recent scientific expedition focused on tagging sharks in the Cocos Islands, in Costa Rica. Dr. Mauricio Hoyos, who uses a technique that involves implanting transmitters to track their movements and study their migratory patterns, had an unexpected encounter that tested not only his experience but also his perspective on these animals. With over 2,000 tags performed throughout his career, his preparation and composure were key to facing the moment with clarity. However, what was most significant was his ability to transform the event into an opportunity to debunk deeply ingrained myths. Far from reacting aggressively, Dr. Hoyos describes how the shark's behavior was restrained, almost as if it had chosen not to harm him. "It spared my life," he states, reinforcing the idea that these species are not killers by nature, but creatures that, like all others, deserve respect and understanding.

At the Saving Our Sharks Foundation, we want to highlight how encounters like this, far from being defined solely by their drama, can generate profound reflections and valuable learning for science, environmental education, and shark conservation worldwide.

What does this encounter teach us?

  1. The shark is not a “killer”As Hoyos rightly points out, the archetype of the aggressive shark is profoundly flawed. This encounter highlights that when sharks react, they often do so in self-defense—as was the case here—and not as relentless predators.

  2. Importance of migration marking and trackingThe timing of the incident allowed researchers to deploy ultrasonic transmitters to gather vital data on when a shark enters and leaves an area, and where it migrates. These tools enable researchers to map underwater corridors that transcend national borders, reinforcing an internationalized conservation approach.

  3. A reminder of our vulnerability and its essential roleThrough his experience, Hoyos emphasizes that sharks have existed for some 450 million years and that we have “invaded” their environment. Sharks, in their role, function as “the immune system of the oceans”: they feed on dead, sick, or weak organisms, and in doing so, contribute to the balance. This encounter invites us to pause the “shark = monster” narrative and assume a role of respect and stewardship.

What impact does this have on our work at the Saving Our Sharks Foundation?

  • Strengthening awarenessThese kinds of stories help change public perception and show that sharks deserve protection, not fear.

  • Support for transboundary conservation policiesThe data obtained from expeditions like Hoyos's and his team's can feed into proposals for marine protected areas that recognize shark migration routes.

  • Incentive for scientific collaborationWhen researchers from different countries collaborate (as in Costa Rica, Mexico, USA), a stronger knowledge network is generated.

  • Reminder of training and preparationHoyos' experience demonstrates that expert behavior in high-risk situations reduces danger.

Looking ahead

The shark encounter that Dr. Mauricio Hoyos experienced in Cocos Island is not a narrative accident, but a turning point that allows us to recalibrate our approach: less fear, more understanding. We must to end the myth of the killer shark, because the reality is different. 
This episode, far from fading away after the news broke, should motivate more action, more alliances, and more respect for sharks and the ocean as a whole.

At Saving Our Sharks Foundation, we feel incredibly fortunate and grateful that Dr. Mauricio Hoyos is part of this conservation journey. Together, we are transforming lives by saving sharks.
