What Scientists Just Discovered About Tiger Shark Migration

Devil rays are some of the most mysterious animals in the ocean, yet most people have never heard of them. In this episode, we sit down with marine scientist Marta Palacios to uncover what makes these animals so unique and why they need protection. From their behavior to the threats they face, this conversation reveals why devil rays deserve far more attention in ocean conservation. Marine biology careers don't always follow a straight path, and Marta's journey proves it. Moving from Spain to La Paz, Mexico, she turned a passion for diving into a career studying mobulid rays. We break down how she built her career, what it's like working in the field, and what early-career scientists can learn from her experience. Ocean conservation depends on people who are willing to take risks, follow their curiosity, and commit to protecting species that most people overlook. Devil rays may not get the spotlight like sharks or whales, but they are just as important to ocean ecosystems, and their future depends on better awareness and action. 👉 Listen to the full episode and learn how you can be part of ocean conservation.

Whale Sharks are the largest fish in the ocean, yet scientists still know surprisingly little about how they live, migrate, and survive. In this episode of the Beyond Jaws podcast, we explore why one of the most iconic animals in the ocean remains scientifically mysterious. Marine researcher Stella Diamant joins the show to explain how studying whale sharks in Madagascar is revealing new insights about their behavior, habitat, and the challenges they face in a rapidly changing ocean. Madagascar Whale Shark Project is uncovering discoveries that could reshape how we protect these gentle giants. Stella shares how she first became inspired to study whale sharks and how collaborations with scientists and organizations like the Marine Megafauna Foundation are helping build one of the most important research programs in the region. From identifying individual sharks to understanding seasonal aggregations, the conversation highlights how field science is slowly solving some of the biggest mysteries about these massive animals. Whale Shark Research reveals a surprising truth: despite their enormous size and global popularity, whale sharks remain one of the least understood large marine animals on Earth. One of the most striking insights from this episode is that many key aspects of their life history, including where they reproduce and where juveniles spend their early years, are still largely unknown. That knowledge gap makes ongoing research projects like the one in Madagascar essential for future conservation. Listen to the full episode.

Angola Project began as a graduate idea, but the real question is this: what happens when you turn a passion into your entire life? In this conversation, Ana Lucia Soares shares why she chose to leave stability in Portugal and commit full time to building shark conservation in Angola, and why that decision matters for ocean protection in underrepresented regions. Shark conservation in West Africa is not simple, and that is exactly the point. Ana Lucia explains what it takes to launch Elizmo Angola, navigate funding uncertainty, create local partnerships, and build trust in communities where conservation infrastructure is still developing. This is not just about sharks; it is about leadership, risk, and long-term impact. Starting an NGO sounds inspiring, but it is also deeply personal and emotionally demanding. One surprising insight from this episode is how clarity often comes not from certainty, but from stepping into uncertainty anyway. The move to Angola was not guaranteed to succeed, but waiting for perfect conditions would have meant never starting at all. Listen to the full episode.

Stereo BRUVs are transforming how scientists study sharks, yet most people have no idea how much we have been missing, and why that matters for conservation. In this episode, we talk with Dr. Kaylee Smitt about how underwater camera systems are uncovering sharks in places humans rarely go, changing what we think we know about abundance, behavior, and ecosystem health. Shark research has long depended on divers, fishing surveys, and tagging, but those methods can miss species that avoid people or live deeper than we can reach. Kaylee explains how stereo BRUVs allow researchers to study sharks without baiting hooks or disturbing animals, giving a clearer picture of how sharks actually use their habitats. Marine biodiversity takes center stage when Kaylee shares how this technology is being used beyond sharks, including in deep-sea environments where data is scarce. One surprising insight from the episode is how often sharks appear in places once assumed to be nearly empty, highlighting how limited human observation has shaped flawed assumptions about ocean life.

Shark conservation faces an unexpected challenge: fear. The biggest threat to sharks is not their biology, it is the stories we tell about them. This episode asks a simple but powerful question, how did one movie shape decades of fear, policy decisions, and public misunderstanding about sharks, and why does that still matter for conservation today? Shark science myths are unpacked as marine scientists explain what sharks actually do, how rare attacks really are, and how misinformation spreads faster than facts. The conversation explores how scientists struggle to communicate nuance in a world that rewards sensational headlines, and why changing the narrative is just as important as collecting data. Public perception of sharks takes center stage with a surprising emotional insight: many shark scientists first became fascinated with sharks because of Jaws, even though the film caused enormous harm to shark conservation. That contradiction reveals a deeper truth about fear, curiosity, and how storytelling can either protect wildlife or push it closer to extinction.
