PRESSURISED: 056 - Colossal squid
March 14, 2025 · 25 min

Coming to you from an Airbnb, above a ski hire shop, next to a construction site in Ushuia, Argentina… It’s a very special episode as we continue to pester Antarctica.

We are here for today is a very special birthday. Our favorite and most elusive colossal squid, Mesonychoteuthis hamiltoni, has been described for 100 years but never seen in its natural environment! We are having a birthday bash for the big girl.

Joined by Kat Bolstad of the Auckland University of Technology, Squid Squad, we learn what we do and don’t know, as well as the project Thom and Kat came up with to try to find it.

 

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:

Luz, Caro Mclaren, Tadhg, Austin Horenkamp, Thora, Lindsey and Harrison

 

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...
