PRESSURISED: 055 - Antarctic Fishes

Our short and to the point PRESSURISED version of episode 55. 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!

Now it’s Thom’s turn to hit Antarctica. He’s out with the Schmidt Ocean Institute on the Antarctic Climate Connections expedition to the Bellinghousen Sea, to the west of the Antarctic Peninsula.

He will record, edit and upload a podcast from there… somehow. This episode may sound a little rougher as a result, but the content is gold as ever… Underrated belter alert.

We talk to Antarctic fishes expert Thomas Desvignes about the fishes that are only found there and their amazing adaptations. Of course, we also have a remote coffee with Andrew.

We’re really trying to make this project self-sustaining so we have started looking for ways to support the podcast. Here’s a link to our page on how to support us, from the free options to becoming a patron of the show. 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!

Check out our podcast merch here! Which now includes Alan’s beloved apron and a much anticipated new design...
