| the fine structure of the drum muscles of the tigerfish, therapon jarbua, as compared with the trunk musculature. | the fibers of drum and trunk muscles of the tigerfish. therapon jarbua, differ greatly in diameter. the myofibrils of the trunk muscles are irregularly oriented, while those of the drum muscles are rolled into spiral or concentric bands. both muscle types possess the sarcomere structure typical of cross-straited musculature. however, the myofibrils of the drum muscles differ greatly in sarcomere length and width from those in the trunk musculature. the trunk muscles contain few mitochondria, whe ... | 1976 | 1000585 |
| karyakartia egyptensis n. sp. (digenea: lepocreadiidae) from the jarbua terapon, terapon jarbua (forsskål) (perciformes: terapontidae), from the red sea and emendation of karyakartia. | karyakartia egyptensis n. sp.
