Stuck in cage in the Ichthyosaur pool (Apprehension)

Here is a screenshot of it:

You also retain the ability to shoot weapons that are normally not working underwater so it seems if you get stuck this way the game doesn’t enable the underwater mode.

yep, same here. Also I had the ability to keep breathing at the same time.

While Apprehension is being mentioned, I just wanted to point out that the levels title didn’t appear at the start.

Same thing happened to me except it was stuck in midair.
