Morphology of the jaw, suspensorial, and opercle musculature of Beloniformes and related species (Teleostei: Acanthopterygii), with a special reference to the m. adductor mandibulae complex [PDF]

open access: yesPeerJ, 2015
The taxon Beloniformes represents a heterogeneous group of teleost fishes that show an extraordinary diversity of jaw morphology. I present new anatomical descriptions of the jaw musculature in six selected beloniforms and four closely related species. A

Phylogeny and Jaw Ontogeny of Beloniform Fishes [PDF]

open access: yesIntegrative and Comparative Biology, 2004
To investigate jaw evolution in beloniform fishes, we reconstructed the phylogeny of 54 species using fragments of two nuclear (RAG2 and Tmo-4C4) and two mitochondrial (cytochrome b and 16S rRNA) genes. Our total molecular evidence topology refutes the monophyly of needlefishes (Belonidae) and halfbeaks (Hemiramphidae), but supports the monophyly of ...

The cichlid oral and pharyngeal jaws are evolutionarily and genetically coupled

open access: yesNature Communications, 2021
Modular, rather than integrated systems are classically thought to allow functional diversity to evolve rapidly. A study of cichlid fish shows integration between divergent jaw systems at the phylogenetic, population, and genetic scales, suggesting ...

The Shape of the Jaw—Zebrafish Col11a1a Regulates Meckel’s Cartilage Morphogenesis and Mineralization

open access: yesJournal of Developmental Biology, 2022
The expression of the col11a1a gene is essential for normal skeletal development, affecting both cartilage and bone. Loss of function mutations have been shown to cause abnormalities in the growth plate of long bones, as well as in craniofacial ...

Regeneration of Jaw Joint Cartilage in Adult Zebrafish

open access: yesFrontiers in Cell and Developmental Biology, 2022
The poor intrinsic repair capacity of mammalian joint cartilage likely contributes to the high incidence of arthritis worldwide. Adult zebrafish can regenerate many structures that show limited or no healing capacity in mammals, including the jawbone. To

Food partitioning of two co-occurring Terapontid fishes, Terapon jarbua and Pelates quadrilineatus, in coastal areas of Trang Province, Southern Thailand [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2019
This study clearly demonstrates that Terapon jarbua and Pelates quadrilineatus showed obvious food partitioning by their dietary ontogenetic changes. The larvae of both species fed mainly on the calanoid copepods. Juveniles of T. jarbua shifted to feed

An integrated genomic approach for the study of mandibular prognathism in the European seabass (Dicentrarchus labrax) [PDF]

open access: yes, 2016
Skeletal anomalies in farmed fish are a relevant issue affecting animal welfare and health and causing significant economic losses. Here, a high-density genetic map of European seabass for QTL mapping of jaw deformity was constructed and a genome-wide ...

Descriptive Anatomy and Three-Dimensional Reconstruction of the Skull of the Early Tetrapod Acanthostega gunnari Jarvik, 1952 [PDF]

open access: yes, 2003
The early tetrapod Acanthostega gunnari is an iconic fossil taxon exhibiting skeletal morphology reflecting the transition of vertebrates from water onto land. Computed tomography data of two Acanthostega skulls was segmented using visualization software

Oxygen minimum zone: An important oceanographic habitat for deep-diving northern elephant seals, Mirounga angustirostris. [PDF]

open access: yes, 2017
Little is known about the foraging behavior of top predators in the deep mesopelagic ocean. Elephant seals dive to the deep biota-poor oxygen minimum zone (OMZ) (>800 m depth) despite high diving costs in terms of energy and time, but how they ...
