Octopus mirror tests are rare in marine science, and this one comes with a genuinely clever setup: put a piece of prey behind an octopus where it can't see it directly, then give the octopus a mirror as its only way to spot that prey. Will it figure out the…
A megamouth shark sighting off South Africa is closing a scientific gap that's stood for nearly 50 years. In this episode of Ocean Decoded Live, shark scientist David Ebert breaks the story of a rare new megamouth shark specimen found on South Africa's west coast, and host Andrew Lewin explains…
Where do AI data centres go when nobody wants them on land? Increasingly, the answer companies are testing is: underwater. Off the coast of Eastport, Maine, a company called DeepGreen has proposed sinking an AI data center onto the sea floor near Kendall Head, right at the mouth of Passamaquoddy…
Community fights back against AI data centre plans off the coast of Maine, and it's exposing a much bigger question about who gets to decide what happens to a shared body of water. In this episode of Ocean Decoded Live, host Andrew Lewin breaks down the Federal Energy Regulatory Commission's…
Talking about the Shark Whisperer movie again, not with a new take, but because Andrew Lewin is revisiting the single video on this channel that got more views than anything else he's ever posted. In this Ocean Decoded Live clip, the marine biologist looks back at the critique he originally…
Lost Shark Guy Dr. David Ebert is one of the most respected names in shark science today, and in this Ocean People profile from Ocean Decoded Live, host Andrew Lewin breaks down why. Ebert is a friend, colleague, and co-host of Andrew's on the Beyond Jaws podcast, and over a…
The deep sea mining problem traces back to a familiar pattern among the executives pushing to extract from the ocean floor. Ocean Decoded Live follows the career of Gerard Barron, now CEO of The Metals Company (TMC), from his start in ad tech running a company called Adstream, through an…
Diva Amon is one of the most recognized names in deep sea science today, and if you don't know who she is, you might not be as plugged into ocean conservation as you think. In this Ocean People profile from Ocean Decoded Live, host Andrew Lewin breaks down who Dr.…
7-arm octopus: it sounds like a mutation, but it's a real, rarely seen deep-sea animal, and MBARI just shared a new look at one. In this Ocean Decoded Live clip, we break down footage the Monterey Bay Aquarium and Research Institute captured back in November 2025, when their remotely operated…
The motive of a deep sea mining CEO is under real scrutiny this week, and we're breaking down what's actually on the record. Gerard Barron, CEO of The Metals Company, is seeking U.S. approval to become the first company to commercially mine the ocean floor for nickel and cobalt, a…
Dolphin shelling is one of the rarest hunting techniques ever documented in the wild, and this episode of Ocean Decoded Live breaks down brand-new drone footage of it in action. Shelling happens when a dolphin chases a fish into a large empty mollusk shell, usually a big sea snail or…
Marine Mammal Scientist Dr. Eman Khwaja joins today's Conservation Spotlight on Ocean Decoded Live. Known online as @whale_detective, she's built a following by explaining humpback whale behavior and marine science in a calm, clear way that host Andrew says he wanted to spotlight because it makes complex research approachable to…
Deep sea hydrothermal vents are home to some of the most extreme ecosystems on the planet. New research suggests they are far less isolated from the rest of the ocean than scientists assumed. In this episode of Ocean Decoded Live, we break down a striking new study on vent-dwelling limpets,…
Marine snow looks exactly like it sounds: a constant, gentle drift of dead plankton, waste, and organic debris sinking from sunlit surface waters down toward the seafloor. It is one of the ocean's most important and least noticed processes, quietly moving carbon and nutrients from the surface into the deep…
How dolphins catch fish is getting a fascinating new answer, thanks to newly published footage. Researchers from the University of the Sunshine Coast, led by marine mammal expert Alexis Levengood, captured the first-ever video of dolphins using seashells as tools to catch fish, a hunting technique called shelling. A dolphin…
New Orca Hunting Behaviour caught on camera is as wild as it sounds, and we're breaking down exactly what's happening and why. Orcas were caught on video doing something researchers say they'd never really documented before: one orca holds a dead mola mola (ocean sunfish) while another rams straight through…
Deep Sea Trawler decks are where Matthew Gianni's story in ocean conservation actually begins, and today we're telling it. He's the co-founder and political/policy advisor for the Deep Sea Conservation Coalition, based in Europe, but he didn't start out as a marine biologist or policy expert. He started as a…
Deep sea hydrothermal vents just got a lot more interesting. Researchers at the University of Tokyo, led by marine biologist Takuya Yahagi, found that three limpet species living at hydrothermal vents carry chemical traces on their shells suggesting they spend their youth feeding in sunlit shallow waters before returning to…
Ocean Sand Mining is facing fierce pushback from local fishers in Indonesia, and we're breaking down why. In this segment of Ocean Decoded Live, we cover a new marine sand dredging proposal off Nubing Island in Indonesia's Riau Islands province, framed by officials as "marine sediment management." No company has…
US Deep Sea Mining just took a major step forward in American waters. In this breaking news episode of Ocean Decoded Live, we break down the federal government's newly posted proposed leasing notice for a deep sea mining sale in the Commonwealth of the Northern Mariana Islands (CNMI), a notice…
