Robotic sea turtle spies on dolphins

Footage of a pod of bottlenose dolphins is taken from a hidden "spy" camera in a robotic sea turtle. John Downer’s new documentary for BBC1, “The Dolphins: Spy in the Pod,” is the result of 900 hours of such footage from cameras hidden in robotic sea turtles, fish and squid.

In one instance a pod of bottlenose dolphins was observed getting high on toxins produced by a specific kind of puffer fish. The dolphins were seen carefully chewing on a puffer fish and passing it around before entering an apparent “trance-like state.”
