World of Sharks

The acoustic world of sharks: how do they hear? With Dr Lucille Chapuis

Do sharks have ears? Are they good listeners? What are they listening for? Do great white sharks get freaked out by orca sounds? And what kind of music do sharks like?! We cover all this and so much more with bio-acoustician and shark hearing expert, Dr Lucille Chapuis. Join us for a fact-filled episode that includes disco sharks, curious humpbacks, putting sharks in 'sleepy-time baths' and R2D2 with a throat problem.

Going back in time with shark skin! With Dr Erin Dillon

Time travel. Ancient coral reefs. Shark sleuthing. The AMAZING properties of shark skin...this episode has it all! We're chatting with Dr Erin Dillon, conservation paleobiologist and researcher at the Smithsonian Tropical Research Institute. Erin's work uses fossilised shark skin (fancy term: dermal denticles) as a window into the past, to understand what kinds of sharks were around on coral reefs thousands of years ago and how that has changed over time. It's a fascinating deep dive into shark life before humans made their mark, and an insight into what healthy reefs could look like with a little bit of help.

Why have sharks been so successful? With Dr James Lea

It's our 50th episode!! To celebrate, host Isla is joined by shark scientist and CEO of the Save Our Seas Foundation Dr James Lea to talk about the amazing evolutionary success of sharks and their relatives. We talk about just how much sharks have had thrown at them over the 440 million years they've existed on this planet (super volcanoes, ice ages, the terror of plants and a mass extinction event called the 'Great Dying'!) and discuss their super-powered adaptations and efficient body plans. Plus, we answer a listener question: how can I get my friends into shark conservation?

How do I build a career in shark science? Featuring the guests of season 4!

Starting out on your own career journey can be a little daunting, which is why we’ve put together this special episode of World of Sharks, filled with advice, experiences and anecdotes from the guests of season 4. We talk about how to make your dreams of working in shark science and conservation a reality – from how to approach professors, to finding your niche, to overcoming setbacks and staying true to yourself.

How might pollution impact sharks? With Franco Cristiani

Plastics. Oil spills. Industrial chemicals. Herbicides. Pesticides…the list of substances that we have dumped in the sea is endless. But scientists are only just beginning to understand the true extent of the impact of marine pollutants on marine life. Fish biologist and SOSF project leader Franco Cristiani is investigating the effects of harmful pollutants on chondrichthyans, using the American elephant fish (a chimaera) as a model species. We invited Franco onto World of Sharks to discuss this important research and learn about the potential consequences of marine pollution on the reproductive health, immune function and overall survival of sharks and their relatives. And, of course, we take some time to talk about the gloriously weird and funky American elephant fish!

Translating science into conservation action with Rob Bullock and Henriette Grimmel

We’re heading back to the Seychelles this week to chat with research and programme directors for the Save Our Seas Foundation D’Arros Research Centre (SOSF-DRC), Dr Rob Bullock and Henriette Grimmel! Both Rob and Henriette have lots of experience and knowledge in the application of scientific research to marine policy, spatial planning and conservation. And, where they live and work – D’Arros, located in the outer islands of the Seychelles – is the perfect example of how science can be applied to protect and restore marine ecosystems. We talk about the magic of D'Arros, the impressive suite of long-term monitoring programmes carried out by the SOSF-DRC, and the long and complex process of designating and managing a Marine Protected Area (MPA). There are also cameos from the Aldabra giant tortoises, baby sharks, Sir David Attenborough and a VERY friendly manta ray called Jackson.

Ghost sharks: chimaeras, the sharks’ forgotten cousins with Dr Luz Erandi Saldaña Ruiz

It's spooky season! And we're taking the opportunity to celebrate some close relatives of sharks and rays who don't get talked about as much as they deserve: the chimaeras. Also known as ghost sharks, spookfish, ratfish and rabbitfish, these ancient creatures glide in the dark of the deep ocean, much of their life shrouded in mystery. Helping us learn more about them is our guest, fish biologist and SOSF project leader Dr Luz Erandi Saldaña Ruiz. In this episode we learn all about Luz's work, which aims to improve the management of data-poor and data-limited fisheries in Mexico and find out all there is to know about the sharks' enigmatic cousins, who Luz works closely with. Digressions include Tim Burton's A Nightmare Before Christmas, sea creatures that defy reality, and a shark with starry skin.

Shark brains: how are they wired? With Dr Kara E. Yopak

Have you ever wondered what a shark’s brain looks like? How the brain of a goblin shark compares to a mako? What makes a whale shark tick? Or…what it’s like to get a shark brain in the post?

These are all things that Dr Kara E. Yopak, shark brain expert and director of the EXCELLENTLY named ZoMBiE lab knows a thing or two about! Kara is interested in what different shark brains look like and how these differences have evolved over time. She looks at variations in brain size between species, as well as differences in how the brain is organised and structured. This information can give us insight into how sharks live, their habitat, and even their behaviour. Grab your lab coats, because neuroscience is served…

Saving sharks in the Seychelles with Ellie Moulinie and Dillys Pouponeau

This week, we are transporting you to a tropical island haven for sharks and rays in the beautiful outer islands of the Seychelles! We will be guided by the wonderful Dillys Pouponeau (@dillyseychelles) and Ellie Moulinie (@miss_tropics), who are research officers at the Save Our Seas Foundation D'Arros Research Centre. D'Arros island and its sister atoll, St. Joseph, have been labelled a 'pristine wilderness', with thriving coral reefs, sandy beaches, lush seagrass beds, dense mangrove forests and clear waters all bursting at the seams with life. But it is that way because of the hard work of the scientists and conservationists at D'Arros to restore, research and protect this incredible environment. In this episode we learn all about D'Arros and its inhabitants, including a whole suite of sharks from baby black-tip reef sharks to fully-grown bull and tiger sharks, and of course, the manta rays. And we find out all about Ellie and Dillys' research into these species, their great adventures into the 'crazy wild' Amirantes islands, and what it was like to grow up in the island nation.

How powerful is a shark’s sense of smell? With Dr Lauren Eve Simonitis

Sharks have a reputation as 'swimming noses' - but just how well can they smell?

This week we are diving into the fascinating world of snoot science with aquatic sensory biologist Dr Lauren Simonitis! Expect the ins and outs of shark noses, along with detours to explore the anti-predator strategies of sea slugs and cuttlefish, a shark that eats its greens, and a type of whale that inks while it poops. And we break down some famous myths about sharks…like do they really go into a feeding frenzy from the mere scent of blood?
