Figure 6From: The auditory roles of the gas bladder and suprabranchial chamber in walking catfish (Clarias batrachus) Correlations between auditory threshold shifts and suprabranchial chamber gas volume at the indicated frequencies. Threshold shifts in each individual after gas removal were plotted against suprabranchial chamber volume. N = 5 for all frequencies. Regression equation with R squared (R 2) and Pearson’s correlation coefficients (r) with p values are shown.Back to article page
