Crossing the tideline Special Part 3: Tiger Sharks... Friend or foe?

The word “shark” is often used to describe a broad range of species, but that can overlook some significant differences. 

Great whites, bull sharks and tiger sharks have different biology, behaviours, movements, diets and population dynamics and those differences matter when we’re talking about how they interact with people and the environments they share.

These three species have been highlighted because they are the species most commonly associated with serious interactions with humans in areas where sharks and people overlap. 

Understanding why that may be, and what makes each species different, is part of understanding the broader picture.

For this series of three episodes, we’re taking a closer look at each of these 3 species individually. 

Each episode is essentially a 101 on the species in focus, covering biology and behaviour, population, growth and recovery, shark encounters and attacks, mitigation, what comes next, and some of the bigger questions surrounding each species.

This is the Bull shark episode and the second episode in this little mini series. The Great white ep is already in the library and the tiger shark ep will drop in the coming weeks. 

The aim is to build a better understanding of the individual species, rather than grouping everything together under the word “shark”. It then becomes easier to understand the differences between species and add a bit more context to the information, research and conversations that surround them.

All 3 episodes are recorded with Dr Paul Butcher, a Principal Research Scientist with NSW Department of Primary Industries and Regional Development (Fisheries), based in Coffs Harbour. Paul is a leading marine researcher who has spent years working across shark research and management in NSW, including the NSW Government’s Shark Management Strategy, shark tagging programs, SMART drumlines and research into post-release fish survival.

If you have any pressing questions from any of the following eps, please comment or DM through as Paul has generously offered to do an ep dedicated to audience questions once the 3 eps have been aired. 

These eps were recorded during August and September, 2026.
