.
Text editors correct this as Who knows what creatures these are?
.
Which is right or both?
1 Answer
The latter is more normal.
These is the subject (not what creatures - that is the complement).
In a direct question we invert the subject and verb (or auxiliary - irrelevant here):
What creatures are these?
In an indirect (or embedded) question, we do not invert, so the subject precedes the verb:
Who knows what creatures these are?
