natgeo Video by @bertiegregory. Yacare caiman are capable of making water dance! When displaying to potential mates and showing members of the same sex who’s boss, they sink down into the water so their backs are just below the surface. They then produce a spooky low frequency booming noise which causes this bizarre spectacle. Shot for @stevewinterphoto, @natgeowild and @natgeo. Follow @bertiegregory for more wildlife adventures.
