popsci.com – The indigenous group live among the islands of Indonesia, Malaysia, and the Philippines. To find food, groups of the Bajau take daily plunges, often more than 230 feet down, to spear fish and other sea animals. In fact, some spend as much as 60 percent of the day diving for food. If an average human tried, they’d probably not survive. So how do the Bajau manage it?
