In search of notothenioid (Teleostei) relatives

Antarctic Science, 2004
Ninety-five percent of the fish species known from the Antarctic continental shelf and upper slope are acanthomorphs, i.e. spiny teleosteans. Notothenioids (suborder Notothenioidei) are acanthomorphs and so is their sister group. Unfortunately, until recently acanthomorph intra-relationships were so poorly known that it was necessary to sample all of ...

Phylogeny of the Amphiliidae (Teleostei: Siluriformes)

Annales des Sciences Naturelles - Zoologie et Biologie Animale, 1999
The freshwater African catfish family Amphiliidae had been reviewed based on the 73 osteological characters with Diplomystidae, dagger Hypsidoridae, Amblycipitidae, Sisoridae, and Bagridae as out-groups. Because the family position of Leptoglanis (Bagridae/Amphiliidae) is under debate, this genus has been taken as an out-group too. Results of the study

The mechanism of movement of the gill-filaments in Teleostei

Experientia, 1947
Bei ruhiger Atmung sind die Kiemenspalten der Teleostier sowohl wahrend der Ein- wie wahrend der Ausatmung dadurch verschlossen, das je zwei einander zugekehrte Filamentreihen der angrenzenden Kiemen sich mit ihren Filamentspitzen beruhren. Nur durch die ganz feinen Spalten zwischen den Lamellen der Filamente hindurch kann das Atmungswasser vom Ein ...

Pancreatic islet cytology of ictaluridae (Teleostei)

Cell and Tissue Research, 1975
The endocrine pancreas of the bullhead catfish, Ictalurus nebulosus, and the channel catfish, I. punctatas was studied by light and electron microscopy. In addition to the usual A, B and D cells, a fourth endocrine cell type was consistently observed in the electron microscope. All endocrine cell types were innervated. The vesicles of most of the nerve

Interrelationships of the ostariophysan fishes (Teleostei)

Zoological Journal of the Linnean Society, 1981
The history of ostariophysan classification is summarized and it is noted that traditional concepts of relationships have never been supported by characters found to be unique to the taxa. We present a new hypothesis of relationships among four of the five major ostariophysan lineages: Cypriniformes, Characiformes, Siluroidei, and Gymnotoidei (Otophysi)

The Epithelial Islets of the Pancreas in Teleostei

Journal of Cell Science, 1904
ABSTRACT The question of the anatomical and functional nature of the islet-like groups of cells occurring within the pancreas of vertebrate animals has been studied by a large number of investigators since attention was first directed to them by Langerhans in 1869.

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.
