There is no difference between Goblins and Orcs as far as being different species. They are basically the same. If I had to name one difference it would be that Goblins are a type of Orc that has developed more to tunnels and caves, whereas Orcs I think of more patrolling in open spaces, such as the plains of Gorgoroth.
Difference between Alligator and Crocodile. Key difference: Alligators are darker in color, nearly black with a u-shaped snout. Whereas, crocodiles are a light tan or olive green in color with a v-shaped snout that is longer and narrow in front. Most people confuse the alligators and crocodiles, as they are both huge, scaly lizards of prey.
