Welcome to World of Sharks, a podcast all about sharks, rays and their underwater habitat brought to you by the Save our Seas Foundation (SOSF). Forget Jaws – there is SO much more to sharks than their fearsome reputation. Join scientist and shark nerd Dr Isla Hodgson as she chats with leading experts in shark science, conservation and storytelling to take a deep dive into the fascinating world of one of the most diverse, well-adapted, enigmatic, misunderstood and threatened groups of animals on the planet.

Tagging hammerheads, tracking silky sharks and exploring a remote coral paradise in the middle of the Gulf of Mexico…This week, we’re diving into the fascinating world of shark trophic ecology with PhD researcher and SOSF project leader Brett Sweezey! Brett is investigating the interactions between predators and prey, and how they influence where sharks go amongst the unique habitats of the Flower Garden Banks National Marine Sanctuary. Join us as we discuss the innovative methods Brett is using, some fascinating early findings, and the challenges and triumphs of studying these incredible creatures in their natural habitat.

A turtle that looks like a pig, and a shark that looks like a plane...in this episode, we're heading to the colourful, diverse lands of the Kikori River in Southern Papua New Guinea to meet researcher and director of the Piku Biodiversity Network (www.pikubionet.org.pg). In 2018, Yolarnie expanded the PBN - which originally focussed on the community-led conservation of the endangered pig-nosed turtle - to include the 45 species of shark and ray that can be found in the Kikori river system. These species include the unusual and understudied winghead shark, one of the few sharks that passes between salt and freshwater to give birth to its young.

Dive into the deep, remote waters of New Zealand's Fiordland with us as we meet the mysterious broadnose sevengill shark and the scientist who is trying to study them: Dr Alice Rogers. Alice's research aims to discover how these ancient creatures are responding to climate change - will the fiords provide vital refuge for the species as our waters get warmer?Along the way, she and her team are uncovering uncovering the secrets of these elusive "grandpa" sharks.

We're taking to the skies to find out what great white sharks get up to when no-one's looking...
From his drone’s vantage, Carlos Gauna — AKA The Malibu Artist — has captured previously unrecorded behaviours of one of the ocean’s most captivating predators, the great white shark. His footage has fascinated viewers from across the globe, challenged misconceptions of white sharks, and even altered Carlos’ own perspective of the species. In this episode we talk about some of these behaviours; from a shark apparently 'eating' kelp to their interactions with dolphins and people. And, we discuss the moment that Carlos captured the first possible newborn white shark on camera - a key discovery that could secure important protections for white sharks in the area.
You can follow along with Carlos' work and see all his incredible footage here:

Tagging tiger sharks, seamount navigation, and a great white shark called Princess Sparkles... This week, we're diving into the fascinating world of shark movement ecology with research scientist Dr Sammy Andrzejaczek to explore how and why sharks move about the oceans - in particular zooming in on their vertical space use and asking why some sharks take frequent dives to depths of over 1,000 metres. We also discuss the potential effects of the lunar cycle, and what white sharks are up to off the coast of central California. And, we take you behind the scenes as Sammy explains some of the different technologies that she uses to carry out this research and live her dream working with these incredible animals in the wild.

We're gonna need a bigger podcast...
In honour of the 50th anniversary of the release of Jaws - one of the most iconic shark movies of all time - we are bringing you a very special bonus episode wholly dedicated to the film. Host Isla is joined by two jawsome guests: shark scientist and science communicator Amani Webber-Schultz (@curly_biologist), and social scientist and Associate Professor in public policy, Dr Chris Pepin-Neff (@csyd2202). Together, they discuss the cultural impact of Jaws and its negative effects on public perceptions of sharks and shark conservation, as well as its positive influences - including sparking the careers of a whole generation of shark scientists. And, they take a deep dive into the film itself, reliving their favourite scenes, sharing behind-the-scenes facts, and dreaming up their own pitches to Hollywood.

They are the most iconic shark species of all time, known for their strength, hunting prowess, and long-distance travel. But there is a lot more to great white sharks than their reputation. They are not the mindless killers that the movies would have you believe – in fact, they are a highly curious and elusive species who continue to surprise us. And someone who knows white sharks inside out is Dr Alison Kock, a marine biologist who has spent the last 20 years studying their behaviour and ecology. In this episode, Dr Kock shares everything she knows about the world's largest predatory fish, including a scientific finding that's hot off the press...
