Secrets of the Bull Shark

Storyline: We know Bull Sharks swim upriver and we know they hunt in the sea. But we've never been able to see it all like this. We see them attack and consume other sharks. We watch their shady hunts in the deep. We follow them up freshwater rivers to pupping grounds. We see them hunt shoals of fish from drones above and we watch as they clash with hippos and crocodiles.
