Recent interactions between the hosts and their guests.

Painting the Town Blue: Artivism and Bringing the Ocean to the Streets with Tré Packard and Akira Biondo
Q: What inspires you about sharks and their role in PangeaSeed's work?
Sharks have always fascinated us, seen as emblematic of ecosystem health, and their story helps drive home broader conservation messages beyond just their species.
Painting the Town Blue: Artivism and Bringing the Ocean to the Streets with Tré Packard and Akira Biondo
Q: Do you have a point where you realized art could be a powerful tool for marine conservation?
We realized early on that images can convey urgency and emotion in ways that numbers alone can't, which helps people engage and take responsibility for their choices.
All Shark, No Bite - How Ocean Acidification Could Affect Shark Teeth with Max Baum
Q: Could you explain what ocean acidification means and what causes it?
It's a chemical change driven by CO2 absorbed into seawater, which forms carbonic acid and lowers pH, making calcified structures harder to build or maintain; the effect is linked to rising CO2 from human activities.
The Secret History of Sharks! Shark Evolution and Adaptations with Professor John Long
Q: What marks the definition of a true shark in the fossil record?
The defining feature is the presence of prismatic cartilage in the skeleton, a tissue that leaves a distinctive pattern in fossils and marks the split from earlier stem sharks.
Nurse Sharks: The Sharks That Like to Cuddle with Sergio Madrigal Mora
Q: What conservation implications do these findings have for Pacific nurse sharks?
Findings help refine baseline knowledge for regional management, underscore the need to consider cross-border movements, and support community-based management approaches, especially in protected areas like St Elena Bay.
