I watch a lot of National Geographic animal type shows.
There was one where two giant male lions had to cross a crocodile infested stream. They watched and waited and waited and waited trying to pick a low activity time and they made their break for it. Swimming as fast as they could, but instantly a big crock made a bee line at them and they were not going to beat him. You could see the closest lion to him watching his approach, and just as the crocodile reared its head out of the water with mouth wide open to grab, the lion actually dived under the water and under the crocodile coming up under him.
It was not a violent hit but it startled the crocodile (their eyes are closed when their mouth is open to attack to protect the eyes) and the crocodile bolted in the opposite direction thinking he was being attacked. Both lions made it the opposite shore.
I had no idea lions knew how to dive nor had the strategic knowledge to know how to counter the attack.
I cannot find that video but i think it was that, that lions maneuver that lead to this infamous finish move...
