Records from Esteros del Iberá

Description


This fish is adapted to aerial respiration, and the specialized organ for this function is the swim bladder.
It lives in the swamps and normally surfaces every 10 minutes; the intake of air through the mouth and its access to the swim bladder has been experimentally proven (Ringuelet, 1969).
