(Clicking sounds by sperm whale)

What you’re hearing right now isn’t a construction site, it’s not a fax machine, it’s not an old dial-up router, if any of you remember those.

This is the sound of the world’s largest predator, and this is what it feels like to swim face to face with these beings.

(Clicking sounds by sperm whale)

So, these clicks are so loud, you can actually feel them in your body. Your body starts heating up after a few minutes.

I swam with these animals about four years ago. Some friends and I had heard that, off the coast of Sri Lanka, these huge congregations of sperm whales would gather in March and April.

So we hopped on a flight, got on a boat, and had the boat drop us off, about six miles off the coast. We sat there in the water, and we waited. One hour became two, two hours became three, till we heard this “tick tick tick tick” sound, like a typewriter, from like miles away.

We looked down, and we saw these two shadows, and this ticking got louder, and louder, and louder. The frequencies, again, were so powerful that you could feel them inside.

These animals came up to us, welcomed us into their pods, and started showering us with these clicks. So, this is a pretty interesting experience for me.

I found out later that these clicks are actually used for communication. These animals also use them to see in the deep ocean.

What they do, is they send out a click, they wait for the echo of that click to come back, and they use that information to form a picture of everything around them. It’s a form of sonar, called echolocation. So that’s pretty amazing, right?

They’re able to see better with sounds than we are able to see with our eyes. But there’s something else in here. Inside of these clicks is encoded information. There is a secret language in here. And the more you focus in on these clicks, the tinier and tinier they get, into more complex structures.

So, not only do sperm whales use these, but other cetaceans, such as dolphins and orcas, also use these. It’s this secret language. And it’s not random. These animals are able to repeat the same discreet codes over and over again, down to the millisecond.

So, scientists have known all about cetacean communication. Back in the ’60s, this guy, John Lilly, had a lab set up, dedicated to solving the dolphin communication problem, in the Bahamas. And he did all kinds of crazy stuff.

He had a dolphin telephone, where he put one dolphin in a tank, on one side of the lab, and another dolphin on the other side of the lab, and he hooked them up through an intercom, and he would listen in, as these dolphins would have these very complex conversations, for hours and hours and hours.

He also had dolphin English language immersion workshops — this is true — where he would have an intern grant dolphins sexual favors, if they learned English words. And this totally worked.

He also did some pretty creepy things, like he shot them up with LSD, tried to figure out if that would help them learn English.

So, what Lily really wanted to do, though, was to figure out the sperm whale communication code. He said these animals are, by far, the most intelligent animals on the planet. They have a form of communication that is far more sophisticated than ours. But you can’t quite put a 60-foot long whale into a lab. It just doesn’t work.

So, for the past 50 years, we’ve been stuck doing this: studying these animals from the deck of a boat. Now, this is very limiting. You can’t see what you’re actually doing, you just have to put these hydrophones off the deck of the boat. But still, with that, they found some pretty amazing things.

They found that, yes, sperm whales have dialects; they found that, yes, they can shoot this click communication in focused sound beams to other whales, across great distances of ocean.

They found that, also, these sperm whales can cram 1,600 micro clicks into a single second, and repeat those over and over, and move discrete frequencies around, and shoot those to other whales.

So, really interesting stuff, but they could not crack the communication code. To do that, you have to get below the surface. You have to see these animals, you have to gauge their behavior.

So, a few years ago, a French researcher and a Belgian free diver had an idea. They thought, “Hmm, what if we try free diving with whales? Maybe we could get close enough to them that way, that they would be able to encounter us, and start communicating with us.”
