The Amazing World of Dolphins and Whales
Dolphins and beluga whales are known for their intelligence. Their brains are the second largest relative to body mass in the animal kingdom behind humans. Recent research has focused on three abilities: Mimicking human speech, remembering the names of things, and engaging in playful physical contact with each other. But the intelligence of dolphins and belugas whales isn't the only thing that's amazing about them. They are also capable of emitting ultra-high frequency signals that help them avoid obstacles, find their prey and even find out how big their prey is. A new kind of sensor inspired by this ability has even found its way into commercial fishing. Tune in to find out just how amazing dolphins and belugas are.
