We hear from Dr Nicola Quick who researches the incredibly elusive beaked whales, a group that likely spends the majority of their time in the deep sea. These interesting whales have been seen diving to depths of 3000 m, which way exceeds the max depth of their more-famous-cousin, the sperm whale (who usually hang out at around 1500m deep).
It also turns out that we as humans have something in common with these deep diving critters: the mammalian dive response. We hear from Dr Ryan ‘Beefy’ Beecroft, a sub engineer and keen free-diver, who explains to us what deep diving feels like when you are an air breather.
What’s more, the Professor tells the story about the infamous Goblet of Hades. If you manage to see this little piece of history in the background of documentaries, please do send a pic in!
We want to say a huge thank you to those patrons who have already pledged to support us:

The Hagfish Incident by Louie Zong
Context:
The incident it is paying tribute to is when a truck carrying Police in Oregon were in a slimy situation on Thursday after a truck carrying 7,500 pounds of live hagfish failed to stop at a construction site and spilled its contents onto the highway and over surrounding cars.
