Circulation and respiration in lungfishes (dipnoi)

Journal of Morphology, 1986
This paper reviews the cardiorespiratory morphology and physiology of the living lungfishes, in the special context of their highly effective use of both air and water for gas exchange. Particular emphasis is placed on describing those features of the circulatory and respiratory systems that distinguish Neoceratodus from the Lepidosirenidae ...

The diversity of beta defensins in lungfish (Dipnoi)

The Journal of Immunology, 2022
Abstract Mucosal surfaces are the first line of defense against pathogens. At these surfaces, mucus containing innate and adaptive immune molecules is constantly secreted to protect the animal host. African lungfish are the extant relatives to all tetrapods and have a dual mode of living, swimming in freshwater during the wet seasons and

Characterization of the dipnoi, a monophyletic group

Journal of Morphology, 1986
Fossil and extant dipnoans form a well-defined group of osteichthyans. Tooth plates, a feature in common for extant and the majority of fossil dipnoans, are not found in all dipnoans. Nevertheless primitive dipnoans can be defined by 21 characters of the head skeleton: bone arrangement in the posterior part of the skull roof, relation between ...

The Structure of Certain Palaeozoic Dipnoi.

Journal of the Linnean Society of London, Zoology, 1923
SUMMARY This paper includes the first complete accounts of the circumorbital region and opercular apparatus of Dipterus valenciennesi, and of the lower jaw of D. platyeephalus. It gives very nearly complete descriptions of the skull, lower jaw, and clavicular apparatus of Sagerwdus and Ctenodus which much extend our knowledge of these fish.

Pulmonary mechanoreceptors in the dipnoi lungfish Protopterus and Lepidosiren

American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 1983
Pulmonary mechanoreceptors in the dipnoi lungfish Protopterus aethiopicus and Lepidosiren paradoxa were identified and characterized both in vivo and in vitro. Both slowly adapting receptors (SAR) and rapidly adapting receptors (RAR) were found, with the majority of receptors being of the slowly adapting type.

Regionalization of axial skeleton in the lungfishNeoceratodus forsteri (Dipnoi)

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, 2005
Differentiation of the axial skeleton into distinct regions, once thought to be characteristic of the Tetrapoda, also occurs in the actinopterygian Danio rerio. In these taxa, the boundary between the cervical-thoracic regions correlates with Hoxc6 expression and morphological features such as position of the pectoral fin and associated nerves, and the
