A phylogenomic perspective on the radiation of ray-finned fishes based upon targeted sequencing of ultraconserved elements [PDF]

open access: yes, 2012
Ray-finned fishes constitute the dominant radiation of vertebrates with over 30,000 species. Although molecular phylogenetics has begun to disentangle major evolutionary relationships within this vast section of the Tree of Life, there is no widely ...

Differences in the trophic ecology of micronekton driven by diel vertical migration. [PDF]

open access: yes, 2019
Many species of micronekton perform diel vertical migrations (DVMs), which ultimately contributes to carbon export to the deep sea. However, not all micronekton species perform DVM, and the nonmigrators, which are often understudied, have different ...

Review of the genus Photoblepharon (Actinopterygii: Beryciformes: Anomalopidae) [PDF]

open access: yesActa Ichthyologica et Piscatoria, 2019
The flashlight fishes of the genus Photoblepharon (Family: Anomalopidae) are herein reviewed, in order to clarify their taxonomy. The genus includes two species Photoblepharon palpebratum (Boddaert, 1781) from the eastern Indian Ocean and the western Pacific Ocean and Photoblepharon steinitzi Abe et Haneda, 1973 from the Red Sea, Oman, and western ...

A new specimen of Birgeria liui (Osteichthyes, Actinopterygii) from the Longobardian (Ladinian, Middle Triassic) of Xingyi, Guizhou Province, South China [PDF]

open access: yesResearch & Knowledge, 2017
Birgeria was one of the largest carnivorous ishes from the Triassic, spanning almost the entire period and, with an almost cosmopolitan distribution. Birgeria liui was originally described based on the incomplete holotype from the Middle Triassic marine ...

A reappraisal of the Italian record of the Cretaceous pachycormid fish Protosphyraena Leidy, 1857 [PDF]

open access: yes, 2017
The genus Protosphyraena is known mainly from partial remains, consisting of isolated blade-like teeth, conical rostra and scythe-like pectoral fins. This paper provides a new insight into partial specimens of the genus Protosphyraena from the Cretaceous

A primitive actinopterygian braincase from the Tournaisian of Nova Scotia [PDF]

open access: yesRoyal Society Open Science, 2018
The vertebrate fossil record of the earliest Carboniferous is notoriously poorly sampled, obscuring a critical interval in vertebrate evolution and diversity.

A giant dapediid from the Late Triassic of Switzerland and insights into neopterygian phylogeny [PDF]

open access: yesRoyal Society Open Science, 2018
A new Triassic neopterygian is described on the basis of a large three-dimensional neurocranium from the Rhaetian (Late Triassic) of the Kössen Formation (Schesaplana, Grisons, Switzerland).

Evolutionary Trends of the Pharyngeal Dentition in Cypriniformes (Actinopterygii: Ostariophysi) [PDF]

open access: yesPLoS ONE, 2010
The fish order Cypriniformes is one of the most diverse ray-finned fish groups in the world with more than 3000 recognized species. Cypriniformes are characterized by a striking distribution of their dentition: namely the absence of oral teeth and presence of pharyngeal teeth on the last gill arch (fifth ceratobranchial).

Northernmost records of Pagrus auriga (Actinopterygii: Perciformes: Sparidae) and Pomadasys incisus (Actinopterygii: Perciformes: Haemulidae) in the eastern Atlantic [PDF]

open access: yesActa Ichthyologica et Piscatoria, 2014
The first records of the redbanded seabream, Pagrus auriga Valenciennes, 1843 (Sparidae), and the bastard grunt, Pomadasys incisus (Bowdich, 1825) (Haemulidae), from Galician waters (NW Spain) are reported herewith. Both findings constitute the northernmost confirmed records of those fishes in the eastern Atlantic.
