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.

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.

Schreckreaktion und Schreckstoffzellen bei Ostariophysi und Gonorhynchiformes

Zeitschrift f�r Vergleichende Physiologie, 1967
1. Nach fruheren Erfahrungen mit 200 Fischarten (109 Ostariophysi, 91 Arten aus anderen Ordnungen, „Nicht-Ostariophysen“) sind Schreckreaktion, Schreckstoff und Schreckstoffzellen auf die Ostariophysi beschrankt und innerhalb dieser Ordnung sehr weit verbreitet.

Ontogeny and homology of the claustra in Otophysan Ostariophysi (Teleostei)

Journal of Morphology, 2006
We studied the ontogeny of the claustrum comparatively in representatives of all otophysan subgroups. The claustrum of cypriniforms has a cartilaginous precursor, the claustral cartilage, which subsequently ossifies perichondrally at its anterior face and develops an extensive lamina of membrane bone.

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 pectoral anatomy of selected ostariophysi I. The characiniformes

Journal of Morphology, 1976
AbstractThe muscles and bones of the pectoral fin of Serrasalmus nattereri, the piranha, resemble those of generalized, lower teleosts with specializations related to a body shape adapted for high‐speed carnivory; the pectoral fins being highly mobile with strong ligaments to the rays.

Analyse de la paléodiversification des Siluriformes (Osteichthyes, Teleostei, Ostariophysi)

Geobios, 1999
Understanding the evolution of the Siluriformes (osteichthyans, teleosts, ostariophysans) and their diversification is achieved through critical interpretation of the role of certain innovations in recognition of the fossil taxa and in the process of the radiation of the group.
