“…1), a partial or total fusion of the paramaxillar and preangular ligaments is very common across teleosts. The resultant compound ligament, the preangulo-paramaxillar, has been previously referred to as the articular-maxillary [38], [39], [65], mandibulo-maxillare posterius [10], [47], [60], maxillo-dentary [66], maxillo-mandibular [28], [48], [54], [67], outer articulomaxillary [68] and primordial, primordiale, or primordium ligaments [5], [8], [13], [69], [70]. The preangulo-paramaxillar ligament is often associated with some of the facial sections of the adductor mandibulae muscle.…”

“…1). The coronomaxillar ligament has been previously referred to as the anterior mandibulomaxillary [71], coronoid-maxilla [62], mandibulo-maxillare anterius [7], [60], mandibulo-maxillary [6], maxillomandibular [71], [72], maxillo-mandibulare anterius [47], maxillomandibulare mediale [70], maxillo-dentary [73], posterior maxillo-mandibular [64], or primordium [74] ligaments. The supramaxillary ligament of Howes [48] and what was termed a “non-osseous structure that resembles a supramaxilla” by Rosen and Patterson [75] also apparently correspond to a modified fibrocartilaginous coronomaxillar ligament (see below).…”

“…As a prime example, Vetter [19] postulated that the lateral facial sections of the adductor mandibulae (the A 1 and A 2 sections of his terminology) in the four teleosts examined in his study were derived from the more medially positioned A 3 . Subsequent studies based on broader surveys across teleosts alternatively proposed that A 3 was derivative of A 2 and eventually also lost in some taxa [5], [47]. Further complicating homology suppositions was the fact that some non-superficial facial divisions of the muscle were also designated as A 1 or a subdivision of that muscle [18], [48], [49] as a consequence of their insertions on the maxilla.…”

The Jaw Adductor Muscle Complex in Teleostean Fishes: Evolution, Homologies and Revised Nomenclature (Osteichthyes: Actinopterygii)

The infraclass Teleostei is a highly diversified group of bony fishes that encompasses 96% of all species of living fishes and almost half of extant vertebrates. Evolution of various morphological complexes in teleosts, particularly those involving soft anatomy, remains poorly understood. Notable among these problematic complexes is the adductor mandibulae, the muscle that provides the primary force for jaw adduction and mouth closure and whose architecture varies from a simple arrangement of two segments to an intricate complex of up to ten discrete subdivisions. The present study analyzed multiple morphological attributes of the adductor mandibulae in representatives of 53 of the 55 extant teleostean orders, as well as significant information from the literature in order to elucidate the homologies of the main subdivisions of this muscle. The traditional alphanumeric terminology applied to the four main divisions of the adductor mandibulae – A1, A2, A3, and Aω – patently fails to reflect homologous components of that muscle across the expanse of the Teleostei. Some features traditionally used as landmarks for identification of some divisions of the adductor mandibulae proved highly variable across the Teleostei; notably the insertion on the maxilla and the position of muscle components relative to the path of the ramus mandibularis trigeminus nerve. The evolutionary model of gain and loss of sections of the adductor mandibulae most commonly adopted under the alphanumeric system additionally proved ontogenetically incongruent and less parsimonious than a model of subdivision and coalescence of facial muscle sections. Results of the analysis demonstrate the impossibility of adapting the alphanumeric terminology so as to reflect homologous entities across the spectrum of teleosts. A new nomenclatural scheme is proposed in order to achieve congruence between homology and nomenclature of the adductor mandibulae components across the entire Teleostei.

Feeding mechanisms and ecology of pycnodont fishes (Neopterygii, Pycnodontiformes)

The functional morphology of the jaw apparatus and the skull and the feeding habits of the extinct pycnodont fishes arc reconstructed in comparison with some extant halecostomes. For this, a short review of the functional units of the pycnodont head is given. The feeding mechanisms of pycnodonts exhibit a transition from simple stcrcotypic feeding kinematics. which are characteristic for primitive actinopterygians, to the modulating feeding kinematics of advanced teleosts and is called limited modulating fccding kinematics herein. Two structural specialisations which are found in halecostomes (operculum with distinct ni. levator operculare and the interopercular bone with the interopercular ligament) are supposed to be absent i i i pycnodonts, whereas they maintain the two primitive couplings for direct mandibular depression (epaxial muscles -neurocraniunr. hypaxial muscles -cleithrum-ni. sternohyoideus -hyoid apparatus). Advanced pycnodonts developed a new structure (upper jaw protrusion resulting in an enlargment of the buccopharyngeal cavity), that is absent in halecomorphs (e.g., h i i i r r cnlvn) and basal pycnodonts (e.g.. tArdunfrons, tMesturzis). The premaxillae and maxillae are firmly fixed in basal pycnodonts, whereas the premaxillac and maxillae are free and movable in advanced pycnodonts. Pycnodonts were benthic foragers with a combination of biting or nipping and suction feeding based on the "truncated cone morphology" of the buccopharytigcai cavity. 11 is concluded. that pycnodonts certainly were omnivorous leeders with a general broad range of prey. But they wcrc also a highly specialised group on generic level in respect to their prey. This is indicated by gut contents, as far as thcy are known. which comprise only monospecific remains of shelled invertebrates (e.g., spines of echinoderms. shells of bivalves). The ecological dcmands of pycnodonts are discussed.Keg words: Neopterygii, Pycnodontiformes, fccding, gut contents, ecology.

“…This apparatus includes a much reduced premaxilla on the ocular side and a shortened mandible with a high coronoid process on the blind side (Van Dobben 1935, Yazdani 1969, Btirgin 1986). In the common sole, Solea solea (L.), as well as in all other members of the family Soleidae, this pattern is correlated with asymmetrical development of the dentition: numerous, thin, pointed, villiform teeth are present on the dentary and premaxilla of the blind side, whereas the jaw elements 'of the ocular side are either edentulous or with feeble teeth' (Cunningham 1890).…”

Anomalies in the cephalic area of laboratory-reared larvae and juveniles of the common sole, Solea solea: oral jaw apparatus, dermal papillae and pigmentation

SynopsisThe post-metamorphic common sole, Solea solea, as well as the other Soleidae and Cynoglossidae, are characterized by oral jaw elements without teeth on the ocular side. A relatively large proportion of late sole larvae and early juveniles, routinely reared in the laboratory, showed dentigerous and shape-modified premaxillae and mandibles on the ocular side. Abnormal jaws were associated with dermal papillae and a lack of pigmentation on parts of the ocular side of the head. These features are probably the result of suppressed epigenetic mechanisms normally active during ontogeny. Insights into the morphological evolution of the soleid jaw apparatus are discussed.
