Do sturgeons have a jaw?
Acipenseriformes have a novel jaw protrusion mechanism, which converts rostral rotation of the hyomandibula into ventral protrusion of the jaw joint. The relationship between jaw protrusion and jaw opening in sturgeon typically resembles that of elasmobranchs, with peak upper jaw protrusion occurring after peak gape.
Can sturgeon breathe air?
A sturgeon is a bottom inhabitant, which is living in cold streaming and very oxygen rich water. A sturgeon does not have sufficient possibilities to pump water round with its gills and will consequently have to swim, just like a shark, in order to breathe in enough oxygen.
How long can a sturgeon live out of water?
They will quickly deteriorate within a few seconds of gill exposure to air, and will seldom survive past the 3- to 5-minute mark without access to water.
Why is my fish floating upside down but still alive?
If your fish is swimming upside down, it has a problem with its swim bladder. Your fish has stopped being able to control its swim bladder and has got stuck with too much air inside it. The reason for this could be constipation, a poor diet, eating habits, or an infection.

Why do sturgeons jump out of water?
Jumping helps the fish equalize pressure in their swim bladder. When the ambient pressure changes during a high or low front, or when the fish move to a different depth in the river, their bladder will expand or shrink. By jumping, they can gulp in air needed to maintain neutral buoyancy.
