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.
An orc (also spelled as ork, orch, or yrch) is a fictional humanoid creature that is part of a fantasy race akin to goblins. Our present-day conception of an orc or ork is one of a race of mythical humanoid creatures, generally described as brutish, aggressive and repulsive, stemming from the writings of J. R. R. Tolkien, where orcs contrast with the benevolent Elvish race. Tolkien developed his idea of the orc from the Old English term orcneas. Quotes
