Mauricio Hoyos, a renowned marine biologist, narrowly escaped death during a research dive at Cocos Island when a Galápagos shark launched a sudden attack. After tagging the shark for scientific monitoring, Hoyos was caught off guard as the predator turned and bit down hard on his head and face.
The bite damaged his air hose and inflicted over two dozen puncture wounds. Despite losing air and bleeding profusely, he controlled his ascent and was rescued by his team. After a 36-hour transit to hospital, Hoyos underwent surgery and continues recovering.
His dramatic story highlights the rare but real risks ocean researchers face in protecting fragile marine ecosystems—and the resilience required in their vital work.
