Beyond Jaws: Exploring Shark Science and Conservation

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...

Beyond Jaws: Exploring Shark Science and Conservation

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...

How Stereo BRUVs Are Revealing Sharks We Never See and Why It Changes Conservation show art How Stereo BRUVs Are Revealing Sharks We Never See and Why It Changes Conservation

Beyond Jaws: Exploring Shark Science and Conservation

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...

South Africa Sharks sit at the heart of Louw Claassens’ career, shaping how she understands conservation, risk, and public trust in science. South Africa Sharks frame this episode through one central question: how do you build a career protecting sharks in a country where fear, media pressure, and politics often overpower science? Louw shares how her path into shark conservation began, the challenges she faced early on, and why her work continues despite public backlash. Shark conservation is not just a scientific pursuit, it is deeply personal work. In this conversation, Louw walks through...

Beyond Jaws: Exploring Shark Science and Conservation

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...

Guitarfish genetics take center stage in this inspiring episode as Bryan Huerta shares how his fascination with sharks at the massive La Nueva Viga fish market in Mexico City sparked his entire scientific path. His early curiosity grew into formal research that now examines the guitarfish sold as Pez Diablo in Mexican markets, where he used molecular tools to identify species and highlight conservation concerns. 

Marine conservation research also shaped Bryan’s career through field experience in the Northern Gulf of Mexico where he helped run longline surveys, learned dissection and biological sampling, and worked with leading shark scientists including Dr. Marcus Drymon and Dr. Nicole Phillips. His story illustrates how dedication, language learning, and crossing borders opened doors in science and advanced important work in the genetics and management of threatened rays. 

Shark research careers come to life in this conversation that highlights Bryan’s upcoming PhD, his marathon-running discipline, and his commitment to filling knowledge gaps for understudied elasmobranchs. His journey offers a roadmap for aspiring scientists navigating international education, language barriers, and the practical challenges of breaking into the shark science world.
