The comparative functional anatomy of feeding in Polypterus senegalus, Lepisosteus oculatus, and Amia calva, three primitive actinopterygian fishes, was studied by high‐speed cinematography (200 frames per second) synchronized with electromyographic recordings of cranial muscle activity. Several characters of the feeding mechanism have been identified as primitive for actinopterygian fishes: (1) Mandibular depression is mediated by the sternohyoideus muscle via the hyoid apparatus and… Expand
Patterns of Evolution in the Feeding Mechanism of Actinopterygian Fishes
TLDR
The major feature of the evolution of the actinopterygian feeding mechanism is the increase in structural complexity in both the pharyngeal and front jaws. Expand
Morphology and Function of the Feeding Apparatus of the Lungfish , Lepidosiren paradoxa ( Di pnoi )
The feeding mechanism of the South American lungfish, Lep idosiren paradoxa retains many primitive teleostome characteristics. In particular, the process of initial prey capture shares four salientExpand
Feeding mechanisms and ecology of pycnodont fishes (Neopterygii, Pycnodontiformes)
TLDR
It is concluded, that pycnodonts certainly were omnivorous feeders with a general broad range of prey, but they were also a highly specialised group on generic level in respect to their prey. Expand
Feeding mechanism and functional morphology of the jaws of the lemon shark Negaprion brevirostris (Chondrichthyes, Carcharhinidae)
TLDR
This study tests the hypothesis that preparatory, expansive, compressive and recovery phases of biting behavior known for aquatically feeding anamniotes are conserved among extant elasmobranch fishes and proposes a model for the feeding mechanism in carcharhinid sharks, including upper jaw protrusion. Expand
Prey capture by Luciocephalus pulcher: implications for models of jaw protrusion in teleost fishes
TLDR
Protrusion is not obligatorily linked with suction feeding; behavioral aspects of the feeding process limit the possible range of biological roles of a given morphological specialization, and make prediction of role from structure risky. Expand
Functional morphology of prey capture in the sturgeon, Scaphirhynchus albus
TLDR
Acipenseriformes are basal actinopterygians with a highly derived cranial morphology that is characterized by an anatomical independence of the jaws from the neurocranium, and have a novel jaw protrusion mechanism, which converts rostral rotation of the hyomandibula into ventral protrusion of the jaw joint. Expand
Osteology, myology and feeding mechanism of Astronotus ocellatus (Pisces, Perciformes)
TLDR
Based on the cinematographic results, it may be inferred that the maximum mouth gape is caused by the sternohyoid-hyoid-interopercular-mandible coupling, and not by the opercular apparatus-mandibles coupling, as the latter acts after the full descent of the lower jaw. Expand
Terrestrial feeding in the Mudskipper Periophthalmus (Pisces: Teleostei): A cineradiographic analysis
TLDR
Functional specializations correlated with terrestrial feeding include obligatory use of pharyngeal jaws for swallowing even small prey items and positioning of the prey in the pharynx by pharyngesis and hyoid movements alone. Expand
Comparative and developmental functional morphology of the jaws of living and fossil gars (Actinopterygii: Lepisosteidae)
TLDR
Principal components analysis of functionally important morphometrics shows that several gar species occupy different regions of functional morphospace, although gars occupy a range of biomechanical states across the continuum of force vs. velocity transmission. Expand
Cephalic muscles of Cyclostomes (hagfishes and lampreys) and Chondrichthyes (sharks, rays and holocephalans): comparative anatomy and early evolution of the vertebrate head muscles
TLDR
This paper provides an updated overview of the anatomy, homologies and evolution of cyclostome and chondrichthyan cephalic muscles, with osteichthyans as primary comparative taxa and infers plesiomorphic conditions for vertebrates and gnathostomes. Expand

TLDR
It is postulated that the switch from insectivorous to piscivorous feeding regimes is accomplished by very minor structural and functional modifications, because the modulatory multiplicity and total range of repertories of the feeding machinery of the two trophic groups overlap significantly.

Asymmetrical Muscle Activity During Feeding in the Gar, Lepisosteus Oculatus
TLDR
Prey capture in the spotted gar was studied by high-speed cinematography synchronized with electromyographic recordings of cranial muscle activity, and the pattern of asymmetrical activity between right and left side muscles is discussed in relation to previous studies of feeding which utilized only unilateral muscle recordings.

Evolutionary Strategies and Morphological Innovations: Cichlid Pharyngeal Jaws
TLDR
The conversion of the preexisting elements into a new and significantly improved cichlid adaptive complex of high selective value may have evolved by rapid steps under influence of strong selection pressure acting on the minor reconstruction of the -genotype which is involved in evolutionary changes of the pertinent ontogenetic mechanisms.

TLDR
While in the Amphibia the kinetic ability of the skull is almost wholly restricted, the dynamic features of the ancestral condition are modified and developed as the basal articulation between the palate and endocranium is retained. Expand

TLDR
Anatomical data presented here reveal that cichlids possess a specific kind of mosaic in which the basic percoid jaw apparatus permits unparalleled optimal adaptations by simple morphogenetic changes while unique and dramatically diverse patterns of muscular coordination involving degrees of synchrony and extensive modulating capabilities of antagonistic muscle groups have been discovered electromyographically.
