So someone has done a bunch of hard work that we're then benefiting from.

Often we go to places where the animals have never seen people before.

And so a big part of the shoot is not filming.

either hiding from the animal, figuring out how to get close and hide, or habituating the animal to our presence so that it knows we're there and is accepting of that.

I mean, in the case of underwater filming, for example, on land, often, if you're hiding from the animal, you can be in a little tent and you can be a couple hundred meters away with a really powerful zoom lens.

Underwater, you're limited by the visibility of the water.

So if the water, you can only see 20 meters, well...

you're not doing any hiding.

Like the animal is going to know that you're there.

So you need to figure out, okay, how do I behave so that the animal is relaxed with me?

I mean, one of my favorite animals to film is the leopard seal.

They're these, I mean, they look like dragons and they live in Antarctica and they can be absolutely enormous.

And they have a very similar skull to a grizzly bear.

So they're just this amazing top predator.

Well, not top predator, killer whale can eat them because killer whales are.

Because killer whales kill.

Yeah, they're bad asses.

We got this.

So with them, I mentioned that all animals have personalities and they have different days.

It's sort of like a lucky dip when you get in the water with a leopard seal.
