“…In the catfish Sisor rhabdophorus, a dorsal fin stridulating mechanism is based on rubbing of a radial or pterygophore on an interspinous bone having file-like ridges (Mahajan 1963;de Pinna 1996). This mechanism is not known in other catfish families.…”

Fishes have evolved multiple mechanisms for sound production, many of which utilize sonic muscles that vibrate the swimbladder or the rubbing of bony elements. Sonic muscles are among the fastest muscles in vertebrates and typically drive the swimbladder to produce one sound cycle per contraction. These muscles may be extrinsic, typically extending from the head to the swimbladder, or intrinsic, likely a more-derived condition, in which muscles attach exclusively to the bladder wall. Recently discovered in Ophidiiform fishes, slow muscles stretch the swimbladder and associated tendons, allowing sound production by rebound (cock and release). In glaucosomatids, fast muscles produce a weak sound followed by a louder one, again produced by rebound, which may reflect an intermediate in the evolution of slow to superfast sonic muscles. Historically, the swimbladder has been modeled as an underwater resonant bubble. We provide evidence for an alternative hypothesis, namely that bladder sounds are driven as a forced rather than a resonant response, thus accounting for broad tuning, rapid damping, and directionality of fish sounds. Cases of sounds that damp slowly, an indication of resonance, are associated with tendons or bones that continue to vibrate and hence drive multiple cycles of swimbladder sound. Stridulation sounds, best studied in catfishes and damselfishes, are produced, respectively, as a series of quick jerks causing rubbing of a ribbed process against a rough surface or rapid jaw closing mediated by a specialized tendon. A cladogram of sonic fishes suggests that fish sound production has arisen independently multiple times.

Osteology and myology of the cephalic region and pectoral girdle of Centromochlus heckelii, comparison with other auchenipterids, and comments on the synapomorphies and phylogenetic relationships of the Auchenipteridae (Teleostei: Siluriformes)

The cephalic and pectoral girdle structures of the auchenipterid Centromochlus heckelii (Centromochlinae) are described and compared with those of two representatives, Auchenipterus dentatus and Ageneiosus vittatus (Auchenipterinae), of the other auchenipterid subfamily, as well as with several other cat shes, as the foundation for a discussion on the synapomorphies and phylogenetic position of the Auchenipteridae. Our observations and comparisons support the idea that the Auchenipteridae and the Doradidae are sister-groups, and also that the clade formed by these two Neotropical families is closely related to the African mochokids. In addition, our observations and comparisons identi ed a potentially new auchenipterid synapomorphy, maxillary markedly elongated proximo-distally.

“…Drumming sounds result from the contraction of sonic muscles in relation to the swimbladder (Ladich, 1997;Parmentier and Diogo, 2006). In the second mechanism, the majority of catfish families use their pectoral spines, and one family, the sisorids, use their dorsal spine only (Mahajan, 1963), to produce stridulatory sounds (Sörensen, 1895;Gainer, 1967;Schachner and Schaller, 1981;Fine and Ladich, 2003;Friel and Vigliotta, 2006).…”

SUMMARYMochokidae are able to produce pectoral spine stridulation sounds. During sound production, high speed videos were used to study the pectoral fin movements to identify the mechanisms involved. A call consisted of a series of pulses and occurred during a spine sweep, which was in fact made up of a series of jerky movements. The morphology of the pectoral spines and associated muscles was also observed in different species. The contractions of adductor profundus and superficial adductor allows adduction and abduction movements (sweep) of the spine, respectively. Simultaneously, the contraction of the arrector ventralis or the arrector 3 of the pectoral spine allows the pulling and pressing the ridges of the dorsal process, against the rough lateral face of the spinal fossa. This results in the rubbing of the ridges of the dorsal process, producing sounds. In Synodontis the analogy for sound production would be a brake shoe pressing against a wheel.

Sound Producing Apparatus in an Indian Catfish Sisor Rhabdophorus Hamilton.

Abstract: SUMMARY Sound producing apparatus in Sisor rhabdophorus is described. The apparatus is formed by the modification of the neural spines of a few of the anterior vertebrae and the first interspinous bone of the dorsal fin. Significance of sound production in this species is discussed.
