You jest (and you jest well)., And yet there is at least one rather-famously documented case of a whale grappling with that very same constraint:

"Another thing that got forgotten was the fact that against all probability a sperm whale had suddenly been called into existence several miles above the surface of an alien planet.

And since this is not a naturally tenable position for a whale, this poor innocent creature had very little time to come to terms with its identity as a whale before it then had to come to terms with not being a whale any more." -DA
