We are thrilled to announce a groundbreaking scientific feat that promises to transform shark conservation. A recent groundbreaking study by Edgar Mauricio Hoyos-Padilla of Saving Our Sharks A.C. and Pelagios Kakunjá, and Dr. James Sulikowski from Sulikowski Lab, has led to an extraordinary discovery that sheds light on the hidden world of bull sharks (Carcharhinus leucas) in the waters of Playa del Carmen, Mexico.
In the realm where breathtaking dives and enigmatic bull sharks collide, a team of visionary scientists embarked on an awe-inspiring journey. With the financial support of Saving Our Sharks Foundation and Ocean Blue Tree, they harnessed cutting-edge technology to explore the depths of these remarkable creatures’ reproductive lives.
Introducing the pioneering study: The successful use of a submersible ultrasound to confirm pregnancy on free swimming bull sharks, Carcharhinus leucas, in a provisioned shark site. This study not only deepens our understanding of bull sharks but also highlights the crucial intersection of scientific inquiry and ecotourism.
When this shark diving activity started, the diving and scientific community did not know if the shark population that visited Playa del Carmen were pregnant, where they came from or where they went to every year. All they knew was that during the winter season, unexpectedly large sharks came to visit, disappeared after some time, and reappeared looking thinner. Now, after 12 years of research and the use of different kinds of technologies, we have scientific data that gives us clues of their movement and most important of all, proves the hypothesis that most of these sharks are pregnant.
Also, with this kind of breakthrough, we demonstrate one more time that diving tourism has not only contributed to local economies but also offered a unique opportunity for scientific exploration.
The study’s uniqueness lies in its innovative use of a fully submersible ultrasound developed by EI Medical. Scientists ventured into the depths to examine free-swimming female bull sharks. In a remarkable twist, they confirmed the presence of embryos in three female sharks, unveiling the hidden marvels of underwater maternity.
This revelation holds paramount importance for shark protection. By understanding the gestation and birthing grounds of pregnant sharks, we gain insights critical to their conservation. This newfound knowledge equips us to protect their habitats and ensure their future survival.
Equally remarkable is the technological leap this study represents. The successful development and use of a new, non-invasive underwater HD ultrasound technology affectionately called the “Aquanaut,” opens new avenues for studying marine life in their natural habitats without disruption.

As guardians of the ocean, we are committed to revealing the wonders beneath the surface and championing the protection of these incredible creatures. The strides we make today lay the foundation for a brighter, more harmonious future for sharks and our marine ecosystem as a whole.
Join us in celebrating this remarkable achievement and embarking on a quest to unravel the hidden tapestry of life in our oceans. Together, we can ensure that the legacy of these incredible bull sharks endures for generations to come. Your support, curiosity, and dedication fuel our mission to save our sharks.
