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.

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.

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.

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.

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.

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.

Shark Week’s Luke Tipple welcomes professional photographer Mike Coots, who lost his leg to a tiger shark attack when he was only 18. But after his horrific injury, he came to love sharks, and became a lifelong advocate for their safety. Luke and Mike discuss his career, his love for photographing sharks, and how to positively approach the big life-changing moments that can happen to any of us.
