Hyoid and ventral gill arch musculature in osteoglossomorph fishes

Developmental evidence for serial homology of the vertebrate jaw and gill arch skeleton

Gegenbaur's classical hypothesis of jaw-gill arch serial homology is widely cited, but remains unsupported by either palaeontological evidence (for example, a series of fossils reflecting the stepwise transformation of a gill arch into a jaw) or developmental genetic data (for example, shared molecular mechanisms underlying segment identity in the mandibular, hyoid and gill arch endoskeletons)....

Functional morphology and biomechanics of the tongue-bite apparatus in salmonid and osteoglossomorph fishes.

The tongue-bite apparatus and its associated musculoskeletal elements of the pectoral girdle and neurocranium form the structural basis of raking, a unique prey-processing behaviour in salmonid and osteoglossomorph fishes. Using a quantitative approach, the functional osteology and myology of this system were compared between representatives of each lineage, i.e. the salmonid Salvelinus fontina...
