The word "some" in the given sentence serves as a determiner. A determiner is a word that introduces a noun and specifies it in terms of quantity or definiteness. In this context, "some" implies an unspecified amount or number of Komodo dragons that meet the criteria of being eleven feet long and weighing more than five hundred pounds. Determiners are used to express the reference of a noun in a context, which can be definite or indefinite, as well as quantified or non-quantified.
Sometimes Komodo dragons can be eleven feet long, and weigh more than five hundred pounds.
