## Resource

Spiral intestines! Curly poop! A shark that eats plants! And…turning your stomach inside out because you ate something dodgy?! In this episode we explore the ins and outs of a shark’s digestive system with animal physiologist Dr Samantha Leigh (@sea_science_sam), an expert in all things shark gut. We learn how a shark’s digestive system is designed for maximum efficiency, the different ways in which they ingest their hugely diverse diets, and how some sharks are able to survive weeks – sometimes months – without a meal. We also take a deep dive into Dr Leigh’s research on the bonnethead – a shark known to chow down on seagrass – and her recent SOSF-funded project, which is using the shark spiral intestine as a model to address one of our greatest environmental conundrums: the removal of microplastics.
