Sand Tiger Sharks and Their Mysterious Behavior

The video explores the Graveyard of the Atlantic, a site off North Carolina's coast known for shipwrecks and sand tiger sharks. Photographer Tanya Hoppermans has dedicated her life to studying these sharks, documenting their behavior and social structures. Using photography, she gathers data to understand why these sharks congregate in large groups, particularly focusing on the presence of pregnant females. The video highlights the mystery of shark aggregation and suggests that these gatherings may serve as a support network for females during pregnancy.
