How do fish maintain buoyancy
WebSharks cope with the salty water by generating lots of the chemical urea. This substance, produced throughout the shark's body, counterbalances the salt in the ocean water. In other words, there's as much salt in the seawater as there is urea (and other chemicals) in the water inside the shark's tissues. So sharks don't lose water the way fish do. WebThe addition of gas to the gas bladder is more complex. As a fish descends, the volume of the gas bladder decreasesdue to increasing pressure, and the fish must add gas to maintain neutral buoyancy. A physostome could theoretically swim to the surface, gulp air and force it into the gas bladder via the pneumatic duct.
