Definitions:

(1) (vary)
to be different, or to change

Vary is often used to describe small differences or changes--especially about things of the same type. It would be more common to say "The weight of full-grown elephants varies depending upon diet and other factors," than to say "The weight of elephants varies from that of mice."
