Dolphins are often seen as friendly, playful animals. But new underwater footage from the US Navy tells a different story. These dolphins, trained to find underwater mines, were filmed hunting fish and even venomous sea snakes in the wild. The footage was recorded using GoPro cameras attached to the dolphins. The late Sam Ridgway, leader of the Navy’s Marine Mammal Program, reviewed this 2022 study before he passed away. The videos show the dolphins catching hundreds of fish by expanding their throats and flaring their lips to create suction. This pulls the fish right into their mouths without biting. Sometimes, they even ‘drilled’ into the seabed to find prey hiding under sand. More shockingly, one dolphin calmly ate eight yellow-bellied sea snakes, known to be highly venomous and possibly toxic. It made high-pitched squeals during this, but showed no illness afterward. The team's audio recordings captured dolphins emitting sonar clicks while searching, then a rapid buzz and squeal when closing in on prey. The squealing continued as they caught and swallowed food. Online viewers were surprised, with one saying, "Dolphins aren’t to be trifled with." Another called them "second biggest bastards of the mammal world." Despite their tough hunting style, the footage shows dolphins as smart, social animals. They remain skilled and powerful predators beneath their cute image, proving they are masters of survival both with and without human observers.
