How often does the Orinoco Crocodile encounters an anaconda?

Answer 1

It's hard to tell, and I'm not sure if there's been any research on this done. It is known that they encounter each other from time to time, and considering both of these animals in the wild would only eat every few weeks or so, they probably don't have a whole lot of trouble with each other.

They are both capable of eating the other as long as it's within certain size limitations. It all depends on who's bigger, who gets the first bite, and where that first bite lands.
