Molecular phylogeny of the armored catfish family Callichthyidae (Ostariophysi, Siluriformes)

Molecular Phylogenetics and Evolution, 2004
The family Callichthyidae comprises eight genera of fishes widely distributed across the Neotropical region. In the present study, sequences of the mitochondrial genes 12S rRNA, 16S rRNA, ND4, tRNAHis, and tRNASer were obtained from 28 callichthyid specimens.

The pectoral anatomy of selected Ostariophysi. II. The Cypriniformes and siluriformes

Journal of Morphology, 1976
AbstractThe pectoral myology and osteology of the cyprinoids Notemigonus crysoleucas, the golden shiner, and Catostomus commersonnii, the common white sucker, resemble those of generalized, lower teleosts in structure and function, except in features related to the manipulation of the massive fifth ceratobranchial of cyprinoids by muscles attaching on ...

Complete mitochondrial genome of the Ictiobus cyprinellus (Actinopterygii: Ostariophysi)

Mitochondrial DNA Part A, 2015
The complete mitochondrial genome of Ictiobus cyprinellus was first determined by a polymerase chain reaction-based sequencing method in this study. The mitochondria was 16,611 bp in length, including 13 protein genes, 2 ribosomal RNA (rRNA) genes, 22 transfer RNA (tRNA) genes and 1 control region.

Development of the cranium and paired fins in the zebrafishDanio rerio (Ostariophysi, Cyprinidae)

Journal of Morphology, 1996
Because of the genetic and developmental information available, Danio rerio stands out as a vertebrate model system in which significant progress in the areas of development and evolution can be made. Despite its increasing popularity, little research has been done on skeletal development.

Morphology and immunohistochemistry of the olfactory organ in the bloodfin tetra, Aphyocharax anisitsi (Ostariophysi: Characidae)

Journal of morphology, 2020
Among teleost fishes, differences exist in the shape, number, and arrangement of the olfactory lamellae, the distribution of the sensory and non‐sensory epithelium, as well as, the abundance of various receptor cells.

Pressure perception inOstariophysi

Experientia, 1960
Blinde, malleuslose Elritzen beantworten unter gunstigen Umstanden schon Schwankungen von 4–7 cm Wasserdruck mit spontanen Reflexbewegungen. Druckzunahme lost — nach bestimmter Latenzzeit — Aufwartsbewegung aus, Druckabnahme Abwartsbewegung. Auch in langfristigen Dressurversuchen wurde entsprechende Reaktion auf Schwankungen bis zu 5–6 cm Wasserdruck ...

The dorsal and pectoral fin spines of catfishes (Ostariophysi: Siluriformes) from the Bauru Group (Late Cretaceous), Brazil: A comparative and critical analysis

Journal of South American Earth Sciences, 2019
Catfish fossils are mainly represented by disarticulated material, most of which is dorsal and pectoral spines. Morphological data on dorsal and fin spines are described. These materials, collected from two sites of the Adamantina and Marilia formations,
