“…The extraocular muscles are assumed to be composed primarily of fast-twitch white fibers, for which the specific tension is known for elasmobranchs (Lou et al, 2002). Among fishes, studies on the extraocular muscles of pike (Esox lucius), goldfish (Carassius auratus), common carp (Cyprinus carpio), chameleon goby (Tridentiger trigonocephalus), Gudgeon (Gobio gobio), blue marlin (Makaira nigricans), butterflyfish (Chaetodon trifasciatus), and carpet shark (Cephaloscyllium isabellum) have found at least two fiber types, small diameter type I (red fibers, slower contraction) and large diameter type II (white fibers, faster contraction) fibers (Kilarsky and Bigaj, 1969;Kordylewski, 1974;Davey et al, 1975;Sterling, 1977;Housley and Montgomery, 1984;Kassem et al, 1988;Bauchot et al, 1989;Zawadowska, 1991;O'Brien et al, 1993). Histochemical analysis, however, identified up to six fiber types in the extraocular muscles of the common carp (Cyprinus carpio) (Zawadowska and Kilarski, 1983).…”

“…The distribution and organization of the fiber types also varies. The extraocular muscles of the pike (Esox lucius) are organized into two populations of fibers arranged in semicircular layers including a layer of small diameter type I slow fibers found distally (away from the eyeball), and a central and proximal (facing the eyeball) region of type IIB and IIC fast contracting fibers (Zawadowska, 1991). In the goldfish, the proportion of red to white fibers differs among the six extraocular muscles, but ranges from 35% to 60% (red; Kilarsky and Bigaj, 1969).…”

Vertebrates utilize six extraocular muscles that attach to a tough, protective sclera to rotate the eye. The goal of the study was to describe the maximum tetanic forces, as well as the torques produced by the six extraocular muscles of the piked dogfish Squalus acanthias to understand the forces exerted on the eye. The lateral rectus extraocular muscle of Squalus acanthias was determined to be parallel fibered with the muscle fibers bundled into discrete fascicles. The extraocular muscles attach to the sclera by muscular insertions. The total tensile forces generated by the extraocular muscles ranged from 1.18 N to 2.21 N. The torques of the extraocular muscles ranged from 0.39 N to 2.34 N. The torques were greatest in the principal direction of movement for each specific muscle. The lateral rectus produced the greatest total tensile force, as well as the greatest torque force component, while the medial rectus produced the second greatest. This is likely due to the constant rotational movement of the eye anteriorly and posteriorly to stabilize the visual image, as well as increase the effective visual field during swimming. Rotational forces in dimensions other than the primary direction of movement may contribute to motion in directions other than the principal direction during multi‐muscle contraction that occurs in the vertebrate eye.

On the Agonistic Display of the Siamese Fighting Fish

The agonistic behavior of the Siamese fighting fish has long been a popular subject for ethologists. While this behavior is well documented, its physiological basis is still poorly understood. One of the most important components of this behavior is the frontal display, in which a fish faces its opponent directly with tonically extended gill covers. As a first step towards establishing this display as a model for behavioral physiology, the musculoskeletal structure of the frontal display apparatus is examined. The opercular bones and the opercular abductor, the opercular dilator muscle, appear to have undergone adaptive modifications that facilitate the display. The opercular bone rotates around the hyomandibular bone through a ball-and-socket joint. Due partly to a reduction of its articulation with the preopercular bone, the operculum can rotate as much as 90° around this joint. The opercular dilator muscle consists of three parts: a deep belly – DOα, and two superficial bellies – DOβ and DOγ The three portions have different origins, but all three insert on the lateral surface of the opercular bone just dorsal to the spheroidal joint. In comparison, the opercular dilator muscle of the sunfish and the goldfish lacks the superficial bellies. Innervation of this muscle is derived from the maxillary division of the trigeminal nerve, all three portions are innervated by axons from the same fascicle, suggesting that they are embryologically related. The superficial bellies consist of uniform, large muscle fibers. The deep belly consists of an external group of large fibers around a central tendon, and an internal group of small fibers. Enzyme histochemistry shows that the external group of fibers consists mostly of fast-twitch fibers, whereas the internal group consists of slow, oxidative fibers. Direct stimulation demonstrates that all bellies can mediate opercular extension. The architectural and biochemical differences among the three portions suggest that they are functionally not equivalent. The fast-fatiguing muscles may mediate the initiation, while the large fibers of the superficial bellies and the small oxidative fibers of the deep belly may be involved in the maintenance of the display.
