The Professor is back on land and Dr Thom is back from Squid Christmas, what a better time to talk about the squishiest of deep sea critters? We talk with George Matsumoto from MBARI all about gelatinous deep sea species. How do we study them? How on earth can we preserve them or even capture their fragile bodies? Plus, we find out exactly what that curious little blue spiky blob was.

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:

Jay Thompson | Sam Watson | Lucy Goodwin

Thanks again for tuning in, we’ll deep-see you next time!
