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 - 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 - 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 - 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.
