Oropharyngeal morphological aspects of Arapaima gigas (Schinz, 1822)

Boletim do Instituto de Pesca, 2022
The study of the functional anatomy of the digestive system of fish, in particular the oropharyngeal cavity, is of great importance because it allows inferences about the feeding habit, mechanisms of capture, selection, and processing of food carried out by different species. Thus, the aim of this study was to describe the anatomical adaptations of the

Chromosomal characterization of the bonytongue Arapaima gigas (Osteoglossiformes: Arapaimidae) [PDF]

Neotropical Ichthyology, 2006
The mitotic chromosomes of the pirarucu Arapaima gigas inhabiting the middle Araguaia River and collected in the municipality of Araguaiana (MT, Brazil) were studied. The chromosomes were analyzed through Giemsa staining, C-banding, Ag-NOR staining and in situ hybridization using an 18S rRNA gene probe. The karyotype had 2n=56 comprising 14 biarmed and

Impact and fracture analysis of fish scales from Arapaima gigas

Materials Science and Engineering: C, 2015
Fish scales from the Amazonian fish Arapaima gigas have been characterised to study their impact and fracture behaviour at three different environmental conditions. Scales were cut in two different directions to analyse the influence of the orientation of collagen layers.
