Everyone has been very busy this month with Thom and the Professor officially describing a new species of blue snailfish, alongside their adventures in Singapore. We hear from one of our old students about the work he’s been doing in deep freshwater ecosystems, which got us thinking about these unique environments and the kind of species that live there. We decided to throw one more curveball away from the deep sea and speak with Dr Melanie Stiassny, an ichthyologist who’s focused her research on the deep-water fish of the Congo River.
We couldn’t go an episode without discussing the latest deep-sea related conspiracy theories. And of course, we hear from Don about how freshwater affects sub manoeuvres.
Check out our podcast merch! Which now includes Alan’s beloved apron and a much-anticipated new design...
