Lots of misinformation and assumptions on this thread. I posted the actual Gen:6-9 event (NIV) in 116, failed to ping you. Sorry about that!
These whales likely just got caught in the receding waters... or not. But, there were no living creatures on land or air left to devour their flesh (unless they made a very long trip really quick).
Psalm 32:10 - Many are the woes of the wicked, but the LORD's unfailing love surrounds the man who trusts in him.
This is just what I was thinking. No need to posit a "super-heated water was what did it" theory. Simply getting trapped by the receding waters would be enough. Then, once the whales were dead, there may not have been any scavengers around in time to scatter the remains.
