Interesting! But how do we know the crocs eat the fruit specifically as mineral or fiber supplement and not just for general sustenance, for the fun of death rolling a pumpkin, or "by accident"?
The sentence "it's not by accident either" indicates clearly observable behaviour. I.e.: A croc needs potassium, then eats a banana. But how did the scientists observe this?
And how do the crocs know which fruit to eat? I guess for them to eat anything with the intention of being provided with minerals or fiber they need to know their fruits?
I have so many questions. I know bears know a lot about plants and some apes are known to use specific plants (as medicine even), but this is indicative of higher intelligence so I'd be curious to hear if anyone knows about how this works in primitive reptile brains.
