Right, that’s what I’m saying. Not enough data to make hard claims, which is why I’m saying this statement is a bit of a stretch:
if a dolphin needs to they can breathe thru their mouths just fine.
As far as I can tell this has happened once ever. I’m not sure that qualifies as “just fine” when there’s more evidence that plugging a blowhole is very bad for the dolphin.
You’d have to have the most insanely strong calves in history to push up using your feet only.
