Video by @bertiegregory. An adult giant otter needs to eat about 2kg/4lbs of fish every single day. Many other species (e.g. herons and fish) have learnt that hanging around these fishing machines can often offer a meal! Unfortunately for these hangers-on, the otters aren't keen on sharing. Shot for a new jaguar show for @natgeowild, @stevewinterphoto and @natgeo. Follow @bertiegregory for more wildlife adventures!
