Damn nature, you scary.

That split second seeing its claws then the camera going underwater looks straight up from a horror movie.

Fucking crazy

Kangaroos, when they don’t think they can win a fight on land, will drag their opponent into the water to drown them. They may also retreat into the water in the hopes that their opponent will give up because they do not want to fight in the water.

If their opponent is willing the fight in the water, there is a fair chance a croc will get involved at some point due to the splashing. The roo basically has accepted death and just wants the best chance of their opponent dying if they win or lose.

Respect to him for doing that - but maybe not for holding a camera the whole time.
