Shark Week: The Podcast - Undiscovered Sharks and the State of the Ocean
Luke Tipple invites “The Lost Shark Guy,” Dr. Dave Ebert, who is personally responsible for finding dozens of shark species that were either previously unknown to science or thought to be extinct. He and Luke discuss why shark populations are a direct indicator of how healthy the ocean is, how to find undiscovered sharks, and why diversity in sharks is essential for marine life.
Shark Week: The Podcast - How Smart Are Sharks?
The discussion turns this week to sharks’ intelligence, and how it varies among species. Host Luke Tipple is joined by Dr. Tristan Guttridge, a behavioral ecologist and veteran of Shark Week whose research has tackled the social smarts, and even personalities, of different kinds of sharks. He sheds light on why we shouldn’t just think of them as dumb fish with rows of razor-sharp teeth. And at the end, our researcher Sierra Kehoe tells us about shark hypnosis.
Shark Week: The Podcast - Lights! Camera! TEETH! Making Shark Docs
Shark Week’s Luke Tipple is joined by longtime filmmaker and Emmy-award-winner Andy Casagrande. He’s filmed and appeared in dozens of shark documentaries, and might just be the most prolific shark cinematographer in history. He talks with Luke about his career, the contentious term “shark porn,” and the future of the industry. And at the end, our researcher Sierra talks about the unprecedented ways that sharks are currently endangered.
Shark Week: The Podcast - Do Scientists Need to Kill Sharks?
Host Luke Tipple welcomes two guests to discuss how researchers can kill sharks in the name of science – and whether they need to at all. The first is Dr. Neil Hammerschlag, shark researcher and founder of Atlantic Shark Expeditions, and an expert on data-gathering in the field. He’s followed by explorer Fred Buyle, a world-record-breaking freediver whose innovative methods of shark tagging are explored. Plus, our researcher Sierra tells us about how a 50-year study changed our understanding of tiger sharks – and much of the work wasn’t even done by scientists.
Shark Week: The Podcast - Do You Have the Guts to Be a Shark Handler?
Host Luke Tipple welcomes a pair of divers – Leigh Cobb and Josh Eccles – who have taken their passion for sharks and turned it into a dangerous career. They explore what it takes to swim with sharks for a living, then go into common myths and facts on what to do in the open water – if you ever come face to face with a shark. Plus, our researcher Sierra drops by with a new species of shark discovered in the freezing depths of the ocean.
Shark Week: The Podcast - Did Alien Tech Crash-Land into the Ocean?
Host Luke Tipple is joined this week by renowned Harvard professor, Dr. Avi Loeb, who recently led a deep-sea expedition to discover if evidence for advanced alien life crash-landed off the coast of Papua New Guinea in 2014. They discuss the recent Congressional UFO hearings, how the last seventy years of research into extraterrestrial life has been potentially misguided, and the challenges of searching for tiny objects on the bottom of the ocean.
Shark Week: The Podcast - How Many Sharks Are Yet to Be Discovered?
Luke Tipple is joined by Shark Week host and all-around adventurer Forrest Galante. They discuss his upcoming special Alien Sharks: South Africa, Forrest’s remarkable talent for finding creatures once believed to be extinct, and how many shark species may still be unknown. Then, our researcher Sierra stops by to tell us about the world’s most prehistoric shark.
Shark Week: The Podcast - How To Have A Career in Shark Science
Shark Week’s Luke Tipple tackles the question “How can I work with sharks?” alongside two experts in the field – and their answers are not always the obvious ones. Luke is joined first by Kelly Link, Associate Curator of the Georgia Aquarium who talks about what it’s like to be an aquarist, how it differs from field work, and how to get yourself noticed. The second guest is Dr. Neil Hammerschlag who goes into detail on what it takes to become a prominent scientist, and what other paths you can take if a PhD isn’t for you. And at the end, researcher Sierra stops by to tell us about the world’s smallest shark.
Shark Week: The Podcast - Why is Tagging Baby Great White Sharks So Important?
Luke Tipple speaks with Dr. Riley Elliott, a marine biologist from New Zealand who recently tagged baby great white sharks, which are rarely seen in the wild. They talk about how climate change is affecting shark pupping grounds, why fishers are wrong to think there are “too many sharks,” and about Dr. Elliott’s Great White App, which allows users to track great white sharks in the ocean.
Shark Week: The Podcast - How Shark Fishing Funds Human Trafficking
Luke Tipple is joined by Pulitzer Prize-winning journalist and author of the Outlaw Ocean Ian Urbina, who has dedicated his life to chronicling crime on the high seas. They discuss the state of our world’s oceans, how nearly 20% of your seafood was likely caught illegally, and the surprising link between modern slavery and the killing of sharks.
