Nitrogen excretion and oxygen consumption under severe hypoxia in siluriform fishes from the Amazon. [PDF]
Abstract Siluriform fishes collected from the Rio Negro and Rio Solimões proved to be highly resistant to aquatic hypoxia. In all four species analysed in this study, aquatic oxygen consumption significantly decreased from normoxic levels at water PO2 values near 1 kPa. Air‐breathing activity was observed only in Sturisoma sp. (Rio Negro).

Using the swimbladder as a respiratory organ and/or a buoyancy structure—Benefits and consequences
Graphical abstract Abstract A swimbladder is a special organ present in several orders of Actinopterygians. As a gas‐filled cavity it contributes to a reduction in overall density, but on descend from the water surface its contribution as a buoyancy device is very limited because the swimbladder is compressed by increasing hydrostatic pressure.
