Question: what is the difference between a crocodile and an alligator wiki?
Answer: Snout shape: Alligators have wider, U-shaped snouts, while crocodile front ends are more pointed and V-shaped. Toothy grin: When their snouts are shut, crocodiles look like they're flashing a toothy grin, as the fourth tooth on each side of the lower jaw sticks up over the upper lip.
