Beyond Jaws: Exploring Shark Science and Conservation

Speak Up For Blue

Dr. David Ebert and Andrew Lewin interview shark scientists and conservationists to find out the steps they took that lead them to study and work with sharks. Interviews include stories of field shenanigans; career choices and advice; and, the science of sharks that may or may not include great white sharks...mostly not.

    Inside Shark Week 2026: Jesse Colaizzi on Alien Sharks Untamed America

    It's Shark Week season again, and Andrew Lewin and Dr. David Ebert are joined for the third year running by Jesse Colaizzi, an award-winning television documentary producer, senior editor, and director of photography who works closely with Forrest Galante. Jesse pulls back the curtain on how a Shark Week episode actually comes together, from scouting locations to the final cut. Jesse joins the show remotely from Gujarat, India, where he is showrunning and editing Vantara's Sanctuary Stories, before turning to his newest project, Alien Sharks: Untamed America, premiering Wednesday, July 29th on Discovery. Built around America's 250th anniversary, the episode traces a journey across the country in search of cryptic and lesser known sharks, including white sharks off Diablo Canyon, a California horn shark, a swell shark located after months of searching, a guitar fish, bonnethead sharks, a swarm of blacktip sharks, a rediscovered tagged sawfish with researcher Dean Grubbs, and a basking shark in Cape Cod Harbor. Along the way, Jesse and the hosts dig into what editors notice that scientists and viewers often miss: coordinated hunting behavior in sharks, how white sharks react to a drone's shadow on the water, the technical tricks used to slow down fast-moving animals on camera, and how years of watching raw footage trained Jesse to read animal behavior the way a birder reads bird behavior. Jesse also shares stories from filming rescued and rehabilitated animals in India, the discipline it takes to run multiple shows at once, and why this year's episode leans into American wildlife, from bison to elk to the Statue of Liberty, rather than the usual landmarks. Key Takeaways Jesse Colaizzi is an award-winning producer, senior editor, and director of photography who works with Forrest Galante on Shark Week and Discovery Channel programming, including Extinct or Alive and Alien Sharks. Alien Sharks: Untamed America premieres Wednesday, July 29th and is built around an America 250 theme, spotlighting cryptic and lesser-known native sharks across the country. The team tracked white sharks, a California horn shark, leopard sharks, a swell shark, a guitar fish, bonnethead sharks, blacktip sharks, a sawfish tagged in partnership with researcher Dean Grubbs, and a basking shark in Cape Cod Harbor. Editors and camera crews rely on subtle behavioral cues, frame rate tricks, and instinct to capture usable footage of fast-moving, unpredictable animals in the wild. White sharks have been observed reacting to the shadow of a filming drone, a small but telling example of how visual and behavioral cues shape what ends up on screen. Sharks display coordinated group behavior when hunting, echoing patterns Dr. David Ebert has documented in his own research on pack hunting. Jesse is currently based in Gujarat, India, working on Vantara's Sanctuary Stories, a series focused on rescued and rehabilitated animals and the conditioning process used to care for them. This year's episode centers the Statue of Liberty and iconic American wildlife such as bison and elk instead of typical landmark imagery, offering a nature-first take on the America 250 theme.

    She Spent Years Tracking Sharks in Crocodile-Infested Rivers

    Dr. Julia Constance is back on Beyond Jaws, and this time she's joining hosts Andrew Lewin and Dr. David Ebert as Dr. Constance. Julia returns fresh off completing her PhD on the natural mortality and movement ecology of two of the world's least understood sharks: the speartooth shark and the northern river shark, both found almost nowhere outside northern Australia and southern Papua New Guinea. Using a long-running acoustic telemetry dataset built by her supervisor since 2013, Julia tracked around 200 tagged sharks across Northern Territory river systems, some for up to a decade, to understand how these animals move, where they go, and what puts them at risk. The conversation digs into just how little is still known about these sharks once they leave the rivers as adults. Julia explains how individuals vanish from the tracking data for years at a time before reappearing at a river mouth, with almost no confirmed sightings of adults in the open marine environment. She and the hosts also compare the relatively stable status of Australia's river sharks to their close relative, the Ganges shark, a species so rare and poorly documented that even basic facts about its biology are borrowed from research on its Australian cousins. Along the way, Julia and Andrew share what it's actually like to do this fieldwork: murky, chocolate colored water, gear retrieval by feel instead of by sight, and working in rivers that hold the largest population of saltwater crocodiles on the planet. The episode also touches on a real and growing concern: proposed water resource development on the Adelaide River, home to the largest known population of speartooth sharks anywhere in the world, and what that could mean for a species already living in an extremely narrow habitat.

    The Big Question at Sharks International 2026: Are We Saving Sharks the Right Way?

    Ocean Conservation feels like it's everywhere, but are we actually making a difference, or just telling ourselves we are? In this episode, we break down what really works in ocean protection and why so many well-intentioned efforts fall short. If you care about the ocean but feel overwhelmed by conflicting messages, this conversation will help you cut through the noise and focus on what truly matters. Marine Science meets real-world impact as Daniel Fernando shares lessons from the field, including the challenges of balancing conservation with human needs. From working with communities to understanding how policies succeed or fail, this episode reveals the hidden systems that determine whether ocean protection actually works or becomes just another empty promise. Shark Conservation takes center stage as we connect this conversation to global efforts like Sharks International 2026, where scientists, conservationists, and policymakers come together to share what is actually working for shark protection. These events highlight a critical truth: success is not just about research, it is about collaboration, trust, and turning science into action that benefits both sharks and people. Sustainable Ocean Action is more than awareness, it is about making decisions that lead to measurable results. One surprising insight from this episode: some conservation efforts can fail not because people do not care, but because they are designed without understanding the people they affect most. That tension changes everything about how we should approach saving the ocean.

    She Built Shark Science Where Almost Nobody Was Looking

    Shark Conservation What happens when an entire coastline is full of species we barely understand, and almost no one is studying them? In this episode of Beyond Jaws, we speak with Ghofrane Labyedh, a rising shark scientist originally from Tunisia who is helping build shark and ray research in Cameroon. You'll hear how she entered marine science, why West Africa remains one of the least understood regions for sharks and rays, and what it takes to create science where little existed before. Marine Biology Careers Ghofrane shares the realities of doing fieldwork, building trust with local communities, working with fishers, and navigating the challenges of conservation in developing research systems. Her story shows that ocean science is not only about data, it is also about people, persistence, and creating opportunities where others see barriers. Women In Science one of the most inspiring moments in this episode is hearing how a young scientist from North Africa is helping lead change in a region where shark research has long been overlooked. It is a reminder that the future of conservation may come from voices the world has ignored for too long.
