One has a round face, like a C for crocodile. One has a pointy face, like an A for alligator. Except it's the opposite of that and makes no sense.
You had me in the first half and tbh, now i dont trust the second half either
It is backwards and dumb. The way I remember is that it's alligator with the fatty, lower-case Greek Alpha: "a", which looks round. And it's crocodile with a sharp, unrealistic C, like this "<".
There's probably an easier way to remember, but it worked for me and it's served me absolutely no purpose to know the difference.
To be fair most people's faces are not the shape of the first letter of their name either.
You can tell because you'll see the alligator later, but you'll see the crocodile in a while
ah yeah that one over there is a murder log and that uther ones in de-Nile.
