Blobfish are typically shorter than . They live at depths between , where the pressure is 60 to 120 times greater than that at sea level, which would likely make gas bladders inefficient for maintaining buoyancy.
Blobfish are generally smaller in size compared to other marine creatures. Their habitat includes depths between , where the atmospheric pressure is 60 to 120 times higher than at sea level, a condition that likely impairs the effectiveness of their gas bladders for buoyancy control.
