Electroreception: The Shark's Sixth Sense with Professor Stephen Kajiura

In this episode, we are exploring the ‘sixth sense’ of sharks – electroreception! We are joined by sensory biologist and shark elasmobranch expert Dr Stephen Kajiura, Professor in the Department of Biological Sciences at Florida Atlantic University (FAU) to discuss how sharks are able to detect minute electrical signals and use this sense to pinpoint prey with mind-blowing accuracy. We also get deep into functional morphology, zooming in on the Ampullae of Lorenzini and the unique morphology of the hammerhead. And, we chat about how electroreception doubles up as a kind of internal shark sat nav, helping them to navigate entire oceans without any landmarks to speak of.
