Shark Behavior and Cannibalism Insights

The video explores the phenomenon of shark cannibalism in Bimini, Bahamas, where lemon sharks prey on their young. Research from the Bimini Shark Lab reveals that 50% of newborn sharks are lost annually due to predation and starvation. The study highlights the survival tactics of young sharks and the predatory behavior of adults, especially during high tide. The cannibalism is attributed to the adults' insider knowledge of juvenile hiding spots, a behavior observed globally in shark nurseries.
