N2 - 1. 1. Pure tone displacement sensitivity and bandwidth were measured from the saccule of the ear in two anabantid species (Trichogaster trichopterus and Helostoma temincki) using microphonic potentials with a 1 μV RMS threshold for the second harmonic of the stimulus frequency. 2. 2. Saccular microphonics were recorded in both species from 80 to 1600 Hz, with lowest thresholds between 100 and 200 Hz. The overall microphonic response curves (sensitivity and bandwidth) of the two species were statistically similar to one another with an analysis of variance, although there were statistically different thresholds at 100 and 800 Hz. 3. 3. The hair cell orientation patterns of the saccular epithelia differ in the two species. Consequently, the comparative sizes of the saccular sensory epithelium and numbers of sensory hair cells were examined. The saccular sensory epithelium of Helostoma is about 40% larger and contains nearly 50% more hair cells than the saccular epithelium of a comparably sized Trichogaster. 4. 4. An extracranial air bubble, located in the suprabranchial chamber, is found in both species. The bubble has direct access to the saccular chamber in Trichogaster through a foramen which is absent in Helostoma. Despite the difference in morphology and the larger numbers of sensory hair cells in Helostoma, hearing sensitivity and bandwidth is similar in the two species. Although the structural differences in the auditory periphery do not affect pure tone sensitivity and bandwidth, other aspects of fish hearing such as frequency discrimination, discrimination of signals in the presence of noise, and/or sound localization ability may be affected by these structural differences.
