Help with Metroid Prime Trilogy

[Konekodemon]

On Metroid Prime 1, I just noticed, according to the player's guide I have 100% research data but there is still one blank spot. Is this an extra Research scan? If so, how and where do I get it?

Is it the final boss, "metroid prime" herself?

No, it's one of the Research Scans that's missing.
