Swim Bladder: A sac or container for air and gasses which helps adjust buoyancy and sometimes acts as an accessory breathing organ. It is attached to the Weberian Apparatus. The Swim Bladder is filled through the diffusion of gasses (mostly Oxygen, but also Nitrogen and Carbon Dioxide) from the blood.
