In this jam-packed episode we cover forgotten Christmas specials, lebensspuren, deep-sea sandwiches and climate crisis sea-shanties (and that’s only in the first 20 minutes)!
We speak to the incredible Charles “Chuck” Fisher, a pivotal biologist in hydrothermal vent research, about these fascinating habitats and the organisms which exist there. We learn about the iconic tube-worms and their specialised adaptations to life in these extreme environments. Plus, Chuck does some of his own myth-busting and sets the record straight on a common tubeworm trope.
Don shares his own experiences of these impressive habitats (and the not-so-impressive lunches that came alongside them). Plus, we hear from you in the form of listener questions, children’s books and (another?!) deep-sea conspiracy theory. Buckle-up for a big one!
We want to say a huge thank you to those patrons who have already pledged to support us.
Thanks again for tuning in, we’ll deep-see you next time!
