How is a crocodile snout different from a alligator snout?

A crocodile's head is more narrow and the snout comes to more of a point as compared to an alligator. An alligator's snout is blunt - more of a U-shape. I try to remember the difference by thinking that if the nose is pointed like a capital "A", then it is not an Alligator. It's a bit tough to remember since it is a negative. Another memory jog - though negative - would be if the snout is rounded (a capital "C" is rounded) it is not a Crocodile.
