Abstract

The sound producing mechanisms of Chilara taylori (Girard) and Ophidion grayi (Fowler) are sexually dimorphic. These mechanisms involve the airbladder, a modified anterior axial skeleton and three pairs of muscles; all have an enlarged first vertebra and a pair of similarly modified and enlarged first ribs. In the male Chilara taylori, two thin convex bones are embedded in the anterior face of the airbladder. Slits are present in the lateral wall of the airbladder just behind the embedded bones. The male Ophidion grayi has a very rigid airbladder. Highly modified third ribs shaped like inverted ram's horns are embedded in the airbladder wall. These ribs encircle a membranous area in the anterior of the airbladder in which a median rocker bone is embedded. The sound producing mechanisms of the females of both species lack specialized bones associated with the airbladder. Their sound producing mechanisms are not as well developed as in the male.
