A digital dissection of two teleost fishes: comparative functional anatomy of the cranial musculoskeletal system in pike (Esox lucius) and eel (Anguilla anguilla)
Advances in X‐ray computed tomography (CT) have led to a rise in the use of non‐destructive imaging methods in comparative anatomy. Among these is contrast‐enhanced CT scanning, which employs chemical stains to visualize soft tissues. Specimens may then be ‘digitally dissected’, producing detailed,...

The adductor mandibulae complex – used in biting – was larger in Esox than Anguilla relative to head size. However, the overall architecture of the adductor mandibulae was also very different between the two species, with that of Anguilla better optimized for delivering forceful bites. Levator arcus palatini and sternohyoideus – which are used in suction feeding – are larger in Esox, whereas the levator operculi is larger in Anguilla. Therefore, differences in the size of functionally important muscles do not necessarily correlate neatly with presumed differences in feeding mode.
