Great White Sharks: Understanding the Apex Predator

The video explores the characteristics and behaviors of great white sharks, particularly those found off the coast of South Africa in False Bay. It discusses their impressive size and speed, their curious nature, and their dietary habits, which rarely include humans. The video explains the role of the ampullae of Lorenzini, specialized electroreceptors that help sharks detect electrical charges in the water. It also highlights the sharks' predatory behavior towards seals, including their ability to breach the water's surface.
