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.
But they have differences, too. Pythons have one more bone in their head than boas do and some additional teeth, and pythons are found in the Old World (Africa, Asia, Australia) while boas live in both the Old World and the New World (North, Central, and South America).
