Today you'll learn about how dolphins and whales may experience the world as a group,

why you go blind thousands of times a day, and white kids are more prone to

grudges than gratitude.

Let's satisfy some curiosity.

If you didn't already think that dolphins and whales are cool, then wait till you hear this. They might experience the world as a group.

What I mean by that is that dolphins and other creatures that use echo location may share a bond that's beyond our human

understanding. Here's the science behind the speculation. Dolphins and whales both thrive in

the dark depths of the sea and the reason they do so well is

because they evolved to use echo location to perceive objects around them.

Here's how that works. The sea mammals emit high-pitched clicking noises that are focused into a sound beam,

and pass through a fatty part of the forehead called the melon. If the sound beam hits something,

it's reflected back and received by another fat deposit in the

animal's lower jaw, then transmitted to the ears. The returning sound beam

carries a ton of information back with it. The size and speed of the beam can tell the

echolocator how far away an object is, how big it is, how fast it's moving, what

direction it's moving, and how dense it is. Dolphins can echo locate an object as small as a golf ball

more than 90 meters away and the clicks of both dolphins and whales can travel a distance many

kilometers away.

All that data likely makes the echolocated things
