Investigating the Mysterious Whale Sharks of Mafia Island | National Geographic

whale sharks of Mafia Island are attracting scientific interest because of their unusual behavior: Unlike other whale sharks, which migrate, these whale sharks stay near the island all year long. Why is the ocean's largest fish hanging around this island off the coast of Tanzania? Researchers from the Marine Megafauna Foundation are investigating this mystery, as well as learning more about the endangered whale shark, since knowledge on them is very limited.
