Seal Island and Great White Sharks

Seal Island, located near Cape Town, is home to thousands of Cape fur seals. These seals face the challenge of evading great white sharks, their superior predators. Researchers Ala Defos and Ryan Johnson study the seals' tactics and the island's geography, which offers both advantages and challenges. The seals must navigate a shark-infested area known as 'The Gauntlet' to reach rich fishing grounds. Despite the dangers, the island provides safety from land predators. In shallow waters, seals are safe from sharks and can play freely.
