A reasonable hypothesis.  Let's extend it.
Jonah comes home after days and nights away.  "Where the hell have you been?", he's asked.  "And why is it that you stink like fish?"  "Well, darling, I know this sounds a tad unbelievable but I was swallowed by a whale and have only just now escaped.  It was horrid, absolutely horrid.  And to be kept away from you was the worst part of it all!"
Ira Gershwin, in the lyric for It Ain't Necessarily So remarked on another instance.
Moses was found on a stream 
Moses was found on a stream 
He floated on water 'til old Pharaoh's daughter 
She fished him 
she says from that stream
