    S3 E11: Befriending Giants: The Secret Lives of Manta Rays

    Professor Kathy Townsend knew she wanted to be a marine biologist from the age of five, and completed her very first dive in a frozen Canadian lake. But it was the moment a five-metre manta ray draped its tail over her shoulder like an affectionate cat that she knew she had truly found her calling. Since then, Kathy has followed manta rays around the world, appeared in a documentary with Sir David Attenborough, and even been swept into a swirling manta-ray feeding vortex. She greets her favourite mantas with a wink, and some even come to her for toothbrush scratches. But these intelligent and gentle giants are under threat. In this episode, Kathy shares the magic of manta rays, the mysteries scientists are still trying to solve, and why the race to understand and protect them has never been more urgent. We just HAD to make this a bonus-length episode because Kathy has SO many incredible stories about mantas which are absolutely not-to-be-missed!

    S3 E10: Dugong Wars: The Fight to Save Mermaids with Professor Helene Marsh

    When Professor Helene Marsh first began researching dugongs on the Great Barrier Reef, the only ones she encountered were dead - tangled in fishing nets. Then, in the 1990s, Queensland became the centre of a fierce conservation battle known as the “Dugong Wars”. No torpedoes were fired, but the conflict between marine scientists, industry groups and governments was intense, as researchers like Professor Marsh fought to remove nets from critical dugong habitat. Today, dugongs face even greater threats, from climate change and habitat loss to extreme weather and declining seagrass meadows. In this episode, Professor Marsh shares the remarkable story of the Dugong Wars, the science behind these elusive “mermaids of the sea”, and the urgent mission to ensure they survive into the future.

    S3 E9: Meet Gary, the King of Nudibranchs (AKA the Ocean’s Craziest Sea Slugs)

    He's broken several world records: largest group skydive, longest scuba dive on a single tank—and the most species of nudibranchs ever found on a single dive (71). He's spent 23 years chasing these tiny creatures, building a global following of more than 60,000 people who are equally obsessed. But what even is a nudibranch—and why are thousands of people going nuts over them? Well, they dress like drag queens, some of them can fire miniature deadly spears out of their flubbery bits, and some can even walk on water like Jesus — but upside down, and with only one foot. In this fun and outlandish interview with the world's biggest nudie fanatic, we get up close and personal with these outrageously beautiful, neon-coloured ocean jewels found in every corner of our seas. Listeners be warned: nudibranchs can be surprisingly addictive. (I mean, JUST LOOK at the nudibranch in the thumbnail image. Does he look like he's the slightest bit bothered by ANYTHING or ANYONE? Go off, you fabulous creature!)

    S3 E5: Eco-Grief: Why Loving Nature Can Hurt - and What To Do About It

    As climate change, coral bleaching and biodiversity loss dominate the news, many people are experiencing something psychologists now call eco-grief or climate anxiety — the emotional response to witnessing environmental change. To unpack the connection between mental health, climate change and our relationship with nature - this week we're joined by Dr Chloe Watfern, an artist and postdoctoral psychology researcher with the University of New South Wales and the Black Dog Institute, who lives on Magnetic Island on the Great Barrier Reef. We'll cover why environmental grief and climate anxiety are normal human responses, how creativity can help people process ecological loss, how parents can talk to children about climate change without overwhelming them, and much more. It’s an honest, thoughtful and ultimately hopeful conversation about loving the places that matter to us — even when they’re under threat.

    S3 E4: Reef Time Capsules: What Coral Cores Reveal About the Reef’s Past

    Did you know coral skeletons contain a record of every flood event in Queensland since 1648? We often hear that climate and water pollution conditions on the Great Barrier Reef have changed dramatically since pre-industrial times. But how do we actually know that? After all, weather records only stretch back just over a century, and systematic water quality monitoring only began in the 1980s. The answer is written in the corals themselves. By extracting a core sample — much like studying tree rings — scientists can read the chemical signatures locked inside the growth layers of coral skeletons, revealing what ocean conditions were like hundreds of years ago. So what stories are those coral cores telling us? To find out, we’re joined today by Dr Stephen Lewis, Senior Principal Research Officer specialising in water quality at James Cook University in Townsville.
