Lauren Meyer's research on white sharks and tiger sharks has unveiled surprising insights about their diet and interactions with human activities. In a recent podcast episode, Lauren delves into her work on these apex predators, focusing on their feeding ecology and the impact of human activities on their diet and nutrition.

• Lauren's study on white sharks involved examining the effects of white shark cage diving on their diet. Despite the use of southern bluefin tuna as bait during cage diving operations, the research found that white sharks still primarily feed naturally, with incidental baits having minimal impact on their diet and nutrition.

• The study also highlighted that non-target species like yellowtail kingfish and silver trevally were consuming leftover baits and burley particles, shedding light on the unintended consequences of shark tourism on other marine species.

• Lauren's postdoctoral research focused on understanding the global diet of tiger sharks, known for preying on turtles and seabirds. The study aimed to explore the potential impact of plastic ingestion by tiger sharks due to their dietary habits.

• An unexpected discovery during the research in Norfolk Island revealed that tiger sharks were predominantly feeding on seabirds rather than cow offal, which was initially believed to be a significant part of their diet.

• Tracking tiger sharks with satellite tags unveiled their consistent migrations from Norfolk Island to New Caledonia, showcasing the extensive movements of these top predators.

• Lauren's research challenges common perceptions about the diet and feeding behaviors of white sharks and tiger sharks, emphasizing the intricate interactions between these predators, their prey, and human activities such as shark tourism and waste management.

• Understanding the dietary preferences and migration patterns of white sharks and tiger sharks is vital for conservation efforts and ecosystem management. By uncovering these insights, researchers like Lauren Meyer contribute valuable knowledge to the field of shark science and marine conservation.

The Global White Shark Conference organized by Flinders University surpassed expectations, drawing 170 delegates and presenting cutting-edge research and insights in the realm of shark science. Initially projected to have around 100 attendees, the conference exceeded this estimate, underscoring the significant interest and enthusiasm surrounding white shark research.

The conference was a collaborative endeavor involv
