Hidden Camera Reveals Unseen Seal Behaviour | Animals With Cameras | BBC Earth

The theory is that this spot is too shallow for sharks. It's a seal equivalent of a paddling pool. A safe and sheltered spot where pups can learn to swim. That is absolutely beautiful. It is probably one of the nicest things I've ever seen underwater. This cove is the only place I can observe these seals beneath the waves. But we want to understand their lives away from the sheltered shallows. And that's what the deployment of these cameras is all about. Our camera testing seal has also been taking a dip. Time to see what the footage reveals. Down to sea. See how the way her shoulder blades are working. And she's about to jump into the water. Here she goes. Into the water. Look at that. As soon as she dives, the camera captures unexpected behaviour. Oh, look at that. Look at that. She's rubbing against the rocks on that green stuff. Wow, yeah, you can see it very clearly there. Yeah. And then she's rubbing the side of her face and neck. And the other animals around her are doing the same thing. They're all doing it. And you've never seen this before? No, I wouldn't have known. I mean, you see them offshore at the surface playing. And this is just brand new stuff. I've never seen this before. Wow. John thinks the seals could be using the seaweed to clean their fur. Brushing up against it to remove parasites.
