Shark Attacks in Recife

The video explores the high incidence of shark attacks along Recife's coastline, which accounts for nearly half of South America's recorded attacks. Authorities have implemented measures like banning surfing to prevent further incidents. Investigations reveal that shipwrecks attract marine life, but nurse sharks are not responsible for the attacks.
