“…This is similar to the sciaenid Cynoscion (Ono and Poss, 1982) but contrasts with the toadfishes Porichthys and Opsanus and the tigerperch Therapon, which possess two triads at the A-I-band border (Eichelberg, 1976;Bass and Marchaterre, 1989;Loesser et al, 1997). However, the number of triads is not necessarily a taxonomic characteristic because both sciaenids and tigerperches (grunts) belong to the order Perciformes.…”

“…Second, the ribbons of myofibrils are shorter and the contractile elements and sarcotubules appear to be less regularly arranged. Occasionally, stacks of membranes, similar to whorl bodies in toadfishes (Loesser et al, 1997), were found between myofibrils. These whorl bodies were continuous with the SR. Third, the sarcomere length was significantly shorter than in sonic muscles (1.6 vs. 2.2. m).…”

“…Contrary to locomotory muscles, drumming muscles possess thin myofibrils and an elaborate development of the sarcoplasmic reticulum (Fawcett and Revel, 1961;Eichelberg, 1977;Ono and Poss, 1981;Bass and Marchaterre, 1989;Fine et al, 1993;Loesser et al, 1997). These features are linked to an unusually rapid calcium cycling necessary for fibers to operate at such high frequencies (Appelt et al, 1991;Rome et al, 1996).…”

Sound‐generating and ‐detecting motor system in catfish: Design of swimbladder muscles in doradids and pimelodids

Catfishes have evolved a diversity of swimbladder muscles serving in the generation of different sounds and probably other acoustic functions. In order to find out if anatomical and acoustical differences are parallelled by fine structural differences, I examined the sonic muscles of the doradid Platydoras and the pimelodid Pimelodus by gross dissections and ultrastructural methods. In Platydoras, the sound-generating (drumming) muscle (DM) inserts on a dorsal bony plate that vibrates the swimbladder. In pimelodids, the large DM attaches directly on the ventral surface of the swimbladder, whereas the small tensor tripodis muscle (TT) inserts on the rostral surface near the tripus, the most caudal Weberian ossicle. Fibers of all three muscles possess an extensive development of sarcoplasmatic reticulum (SR) in association with very thin myofibrils (MF) but differed widely in their arrangement. In Platydoras, ribbons of MFs are arranged radially around a central core. Mitochondria were found within the core and the peripheral sarcoplasm. Pimelodus does not have a differentiated core and the cross-sectional area of DM-MFs is about 15% larger as determined by stereological measurements. The TT possesses shorter sarcomeres and more mitochondria than DMs, which were primarily found between MFs. This suggests faster contraction properties and greater resistence to fatigue compared with sonic muscles. Data indicate that the higher amount of DM-myofibrils in pimelodids might result in stronger muscle contractions and, presumably, in higher sound intensities. The fine structure of the TT reveals that contractions most likely prevent transmission of swimbladder vibrations to the inner ear via the Weberian ossicles during vocalization.

“…According to Orlov et al, (1989), the fusion-associated vesicles are always present below the plasmalemma of more advanced myogenic cells (Loesser et al, 1997). In fishes, fusion-associated vesicles have been observed during myogenesis in O. mykiss (Nag and Nurse, 1972), M. glutinosa (Sandset and Konrneliussen, 1978) and Th.…”

“…Generally speaking, swimbladder sounds have a fundamental frequency ranging from 75 to 300Hz, which would correspond to the muscle contraction rate, placing sonic muscles among the fastest in vertebrates (Rome et al, 1996;Loesser et al, 1997;Connaughton et al, 2000;Fine et al, 2001). The average dominant frequency of pulsed sounds in several carapid species varies between 40 and 340Hz (Parmentier et al, 2003;Lagardère et al, 2005;Parmentier et al, 2006a).…”

SUMMARYThe anatomical structures of the sound-producing organ in Ophidion rochei males present an important panel of highly derived characters: three pairs of putatively slow sonic muscles; a neural arch that pivots; a rocker bone at the front pole of the swimbladder; a stretchable swimbladder fenestra; a swimbladder plate; and an internal cone that terminates in a pair of membranes in the caudal swimbladder. Male courtship calls are produced nocturnally and consist of trains of 10 to 40 pulses that increase in amplitude and decrease in rate before exhibiting alternating periods of ca. 84 and 111ms. Each pulse includes an unusual waveform with two parts. Pulse part 1 is a single cycle followed by a longer duration pulse part that exhibits gradual damping. Sounds and morphology suggest two hypotheses on the sound-producing mechanism. The 'pulley' hypothesis would require an alternate contraction of the ventral and dorsal muscles to form the two parts of each pulse. The 'bow' hypothesis involves a release mechanism with the sustained contraction of the dorsal muscle during all of the call, and the rapid contraction/relaxation of the ventral muscle to form each pulse.

Embryonic, juvenile, and adult development of the toadfish sonic muscle

Abstract: Immature muscle fibers formed embryonically in the larval period have a different morphology from immature fibers in adults, suggesting that splitting rather than SCs is a major source of new fibers in adults.
