The Deep-Sea Podcast

We’re back on the elasmobranch train with our latest episode all about deep-sea sharks!

We speak with Justin Cordova, co-founder and deputy director of The Rogue Shark Lab all about the fascinating world of deep-sea sharks! What makes them different from their shallow-water relatives? Why do their eyes glow green? How exactly do you get into a career in deep-sea shark research?

The Professor is trapped in paradise (somewhere in Fiji) whilst he quarantines before his next big offshore expedition. But he’s not alone - alongside his new pal Roger (the guard gecko) he's quarantining with deep-sea celebrity, Jason 'J-Rod' Rodriguez. The famed SuBastian ROV pilot is joining Alan on this next leg of the expedition to the Tonga Trench. Make sure you're following us to hear all of the updates in our next episode!

Andrew is back from his travels and was just as excited about our Lake Baikal episode as us! In this month's Coffee with Andrew segment, he talks us through the unbelievable similarities between deep-ocean and the deep-lake fish of Baikal.

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

With Dr Thom and The Professor busy prepping for their upcoming expeditions offshore, we had time to squeeze out one more episode before they set sail.

We caught up with the legendary Di Tracey from NIWA to talk all things deep-water corals. How they live, what makes them different from their shallow water relatives, and how they are adapted to life in the deep dark ocean. Di's long career in deep-sea ecology is also intertwined with her extensive work in making the marine sciences a better place for women to work. She talks us through what it was like to begin her career offshore, often being the only woman on board, and how she helped change the industry for the better.

In the news this week we have a few exciting new updates. We can indeed confirm that as of our last episode where we spoke about the vulnerability of subsea cables, there were multiple apparent attacks and cables were cut. We can only assume that hostile nations do indeed listen to the deep-sea podcast (thanks for subscribing!).

Andrew is back from his stint offshore and he is chock-full of stories for us. Brand new dragonfish species, near-misses with box jellyfish and also some cookie-cutter sharks. It's all happening!

We’re really trying to make this project self-sustaining so we have started looking for ways to support the podcast.

This month we're talking about the flattest of the elasmobranchs: the bottom-dwelling batoids - the deep sea rays and skates!

We’re kicking off our cartilaginous fishes (Chondrichthyes) mini-series with the batoids - the rays and skates! Sharks are often associated with the deep sea, but did you know that batoids have been observed as deep as 3000m?

We speak with Will White who researches elasmobranchs across the world and who has described 50 species! He talks us through the differences between sharks rays and skates, and how these species utilise the deep sea. We hear about their fascinating (and hugely varied) reproductive strategies like those that are viviparous (will keep the eggs in their uterus) and others that are oviparous (will lay the eggs).

It wouldn’t be a Coffee with Andrew segment without a memorable insight into the world of a fish curator - and this month’s segment is no different! This time, Dr Thom asks Andrew about an unexpected factoid in one of Andrew’s publications: ‘Yolk smells and tastes like sweetened condensed milk’. We find out exactly how Andrew knows this.

These little oddballs are closely related to sharks and rays but often go unmentioned. They are full of intriguing quirks, from lacking a stomach to possessing a reproductive appendage on their head! We speak with Dr Brit Finucci from NIWA, a lover of deep water sharks and champion kicker of heads (she is also a competitive Muay Thai fighter) all about these fascinating fishes and why they are so interesting.

We also speak with Leo Richards from Natural World Facts about his journey into making deep sea documentaries. If you have ever searched for deep-sea videos online, then you will have definitely come across Leo’s content, as his captivating way of sharing the deep-sea has reached millions of people.

Talking about high-quality content, The Professor has been joined offshore by a team of filmmakers, ready to capture the latest in hadal research. So expect some highly professional footage to come out in the next few weeks!

Finally, Andrew talks us through some physical features of the Chimera, including its pretty hefty defensive spine and some gnarly stories about things getting impaled.

Tales of monsters persist to this day and there’s no better place to hide them than in the deep sea. We are joined by paleontology student and cryptozoology blogger Tyler Greenfield to look at some of the most famous sea monsters and see if there is any truth to the stories. We discuss megalodon, globsters, plesiosaurs/Nessie and all manner of strange carcasses that wash up from time to time.

We have a good hard listen to The Bloop and I call upon an expert in the undersea calls of marine animals, Nicky Harris. She also has a tale from the high seas for us... a rather grizzly bit of nature in action. People in the front row will get wet.

Also in this episode, we talk about glowing sharks, the largest bioluminescent vertebrate. Soft robotics to the planets deepest places and Alan picks a fight with a polar bear, taking on The Octonauts’ very own Captain Barnacles.

Finally, we hear from Don Walsh, who shares some ocean myths that went on to have a grain of truth.
