We might be a little late this month but we’ve packed in as much as we can with this one. We’re covering all the latest deep sea news, including new deep sea habitats, octopus gardens and brand new amphipod species. Plus, we hear from Becca Nicholls about her experiences of working as a woman offshore, and how old superstitions are still very much a thing.
Two new species of amphipod.
Some mariner superstitions are indeed interesting.
Our very special guest this month is the fantatsic Kerry Walton from the Te Papa Museum in New Zealand. Kerry talks us through the weird and wonderful world of marine molluscs, from the deep to the not so deep, and what makes them fascinating to study.
We learn about the very interesting Chainmail snail (Chrysomallon squamiferum), or as some call it ‘the scaly-foot snail’ (but we all agree that ‘chainmail snail’ is way cooler). Plus we hear all about the unbelievable species of limpets that survive on baleen from whalefalls, and those that live on human hair in estuaries (?!?!).
Friend of the show, Susan Casey has also just released her new book The Underworld in which Dr Thom and the Professor make an appearance! In her newest novel, Susan takes us on a journey through the history of deep-sea exploration, from the myths and legends of the ancient world to the scientists who are just beginning to understand the mind-blowing complexity and ecological importance of the quadrillions of creatures who live in realms long thought to be devoid of life. It’s so great to see this book finally out there after years of hard work. Get yourself a copy here. Want to hear Susan’s episode of the podcast? Check it out here.
We want to say a huge thank you to those patrons who have already pledged to support us!

Baleen - The hair-like filaments found in certain whales which function similarly to teeth, to filter seawater for food.
Cephalopod - A member of the mollusc class consisting of squids, octopus, cuttlefish and nautilus.
Chirality - Chirality is a property of an item that means it cannot be superimposed on its mirror image, as seen in the left and right hands.
Chitinous - Made of chitin (the material that gives strength to the exoskeletons of crustaceans, insects and fungi walls).
Commensal relationship - A long-term biological interaction in which members of one species gain benefits while those of the other species are unaffected.
Conspecific - Belonging to the same species.
Dexterally - Latin for right-turning.
Keratin - A structural fibrous protein that forms hair and nails.
Mollusc - The second-largest phylum of invertebrate animals, after the Arthropoda. Includes snails, clams, osyters, limpets, octopus, squid etc.
