[en] In teleosts, feeding is effected principally by suction and food is handled by the branchial
basket. Preys are carried to the oesophagus by the pharyngeal jaws (PJs). The pharyngobranchial bones constitute the upper pharyngeal jaws (UPJs) and the 5th ceratobranchial bones, the lower pharyngeal jaws (LPJs). In lower teleosts, these jaws have well-separated spindly parts attached to the neurocranium, pectoral girdle, and hyoid bar; they only transport food and LPJ activity predominates. In acanthopterygians, the PJs become stronger, the left and right ceratobranchials fuse into one LPJ, and the pharyngobranchials
join together to form two big UPJs articulating with the neurocranium. In labrids and scarids,
the LPJ is also joined to the pectoral girdle. In acanthopterygians, a new retractor dorsalis muscle gives the UPJs the major role in food chewing and transport. Cypriniforms have developed original PJs with strong 5th ceratobranchials opposed to a postero-ventral neurocranial plate. Small-sized preys and food particles are seized by the gill rakers, small skeletal pieces supported by the branchial arches.
