PRESSURISED: 031 - Hydrothermal vents with Charles ”Chuck” Fisher

29 minutes

Our short and to the point PRESSURISED version of episode 31. If you don't have time for the full episode and want to get right to the science without any of our waffle, this is the place to be!

We’re continuing on our iconic deep-sea habitat trilogy with the episode you’ve all been waiting for… HYDROTHERMAL VENTS!

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). Buckle-up for a big one!
