At the recent Television Critics Association winter 2018 press tour, producers said the series was inspired by scientists who have been studying animal groups via cameras attached to the animals.
Gordon Buchanan, on-screen presenter/camera operator, said different animals reacted differently to wearing the cameras but they generally seemed to forget they were there.
"With the cheetah, one, the biggest reaction we saw was a little kind of readjustment of the camera being on its head," he said. "Then after that, they're so predatory, they just want to hunt, so it doesn't matter. They'll hunt with a camera on their head or they'll hunt without a camera. They just want to do what they do best."
