"Difference Between" or "the difference between"

[cherran]

What is the proper title for the article which compares two things -
"difference between" or "the difference between"
eg :
"difference between alligator and crocodile" or
"the difference between alligator and crocodile"

Thanks in advance

Is it possible to explain why they should be plural?
