Ontogeny and homology of the neural complex of otophysan Ostariophysi [PDF]

open access: yesZoological Journal of the Linnean Society, 2006
The development and homology of the neural complex in the ostariophysan subgroup Otophysi were studied, including for the first time representatives of all four major otophysan lineages. Previous hypotheses concerning the homology of the different elements of the neural complex have also been reviewed and these are discussed in light of our new ...

The Distribution of the Fishes of the Order Ostariophysi [PDF]

open access: yesBijdragen tot de Dierkunde, 1922
The Ostariophysi are Teleostean Fishes in which the air bladder is connected with the internal ear by a chain of ossicles, the Weberian ossicles, which are modified elements of the anterior vertebrae. Although the order is a large and varied one it is undoubtedly natural, and its importance in Zoogeography arises from the fact that it is dominant in ...

SYSTEMATIC REVISION OF THE GENERA OF PANGASIIDAE (SILURIFORMES, OSTARIOPHYSI) [PDF]

open access: yesIndonesian Aquaculture Journal, 2008
The family Pangasiidae belongs to the suborder Siluroidei, order Siluriformes, and suborder Ostariophysi. Since the groups were established as Pangasiini Bleeker, 1858; its content and classification have been greatly changed. Judging from the literature, the main constraint to cultivate wild species and to optimize the production of cultured species ...

Overlooked biodiversity of mitochondrial lineages in Hemiodus (Ostariophysi, Characiformes)

open access: yesZoologica Scripta, 2020
AbstractHemiodus is the largest genus of the South American freshwater fish family Hemiodontidae, with 23 valid species. However, the species‐level diversity of Hemiodus remains uncertain since morphological studies have indicated additional species. Also, the phylogenetic relationships among species and species boundaries within this genus are still ...
