We’re continuing on our iconic deep-sea habitat trilogy with the episode you’ve all been waiting for… HYDROTHERMAL VENTS! 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 tube worm 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’ve been off-piste for a while now so we thought we’d jump straight back into the deep sea with a series of episodes on deep-sea habitats. We’re starting off strong with a huge episode on seamounts! We speak to a friend of the show, Ashley Rowden who’s an expert in all-things benthic and we find out why seamounts are just so cool. We also get a little distracted and reminisce about the ultimate offshore championship: sausage-fest. 

We get to hear from the scientists on board the RRS Discovery who are currently on an expedition to discover the life that exists on the seamounts surrounding St Helena and the Ascension Islands. A couple of our friends on board also recall their ‘crossing the line’ experience, and how they’re finding working on board a research vessel.

We have huge news! You’ll be very excited to hear that we have released a new design for our merch, featuring our favourite parasite - the tongue-eating isopod, Cymothoa exigua! A perfect gift this holiday season for the whole family.
