You discover an unusual marine organism. To determine its taxonomic classification, you consult a key, but it leads to conflicting results with a previously published monograph. Assuming both resources are reliable within their scope, what is the MOST likely explanation for the discrepancy?
The key is outdated and needs revision.
The monograph is too specialized and overlooks common variations.
The organism may represent a newly discovered species or a variant not yet documented in the monograph.
There's a fundamental error in the taxonomic system itself.
