I posted this article previously but without the volume and page
information. Here you are:

N. C. Kierl and C. E. Johnston (2010): Sound production in the pygmy sculpin
Cottus paulus (Cottidae) during courtship and agonistic behaviours. J. Fish
Biol. 77 (6), 1268-1281.

Abstract: A field study examined sound production in the pygmy sculpin
Cottus paulus, a threatened species found only in Coldwater Spring (Coosa
River drainage), Alabama where the study was conducted. Two distinct call
types are made during both courtship and agonistic encounters: a single
knock and a knock train. The duration of the knock train significantly
differs between contexts, while the signal structure stays the same. Knock
trains are longer when the intended audience is a female, while short and
abrupt when intended for a male intruder.

butterflyfishes (Chaetodontidae): ?hearing generalists' on noisy coral
reefs? J. Fish Biol 77 (6), 1406-1423.

Abstract: Analysis of the morphology of all three otolithic organs
(sacculus, lagena and utriculus), including macula shape, hair cell
morphology, density, orientation pattern, otolith morphology and the spatial
relationships of the swimbladder and ear, reveals that butterflyfishes in
the genera Chaetodon (which has anterior swimbladder horns) and Forcipiger
(which lacks anterior swimbladder horns) both demonstrate the ear morphology
typical of teleosts that lack otophysic connections, fishes that have
traditionally been considered to be ?hearing generalists'.
