Keratinization of the epidermis of the Australian lungfish Neoceratodus forsteri (dipnoi)
Journal of Morphology, 2003AbstractThe differentiation of the epidermis in sarcopterigian fish may reveal some trend of keratinization followed by amphibian ancestors to adapt their epidermis to land. Therefore, the process of keratinization of the epidermis of the Australian lungfish Neoceratodus forsteri was studied by histochemistry, electron microscopy, and keratin ...

Osteogenesis in the Australian lungfish, Neoceratodus forsteri (Osteichthyes: Dipnoi)
Australian Journal of Zoology, 2022Several types of bone development are present in the Australian lungfish, Neoceratodus forsteri, the only extant member of the family Neoceratodontidae. In this species, dermal and parachondral bones form around the chondrocranium and mandible, to protect the brain and sense organs, to support the dentition and to facilitate oral function.

Fine structure of the spermatozoon of the Australian lungfish Neoceratodus forsteri (Krefft)
Journal of Ultrastructure Research, 1971An examination of the mature spermatozoon of the Australian lungfish showed it to be distinctly divided into three parts: (a) A head, the foremost tapering end of which forms an acrosome; a very elongated nucleus lies behind the acrosome; two rod-shaped structures extend from the point of the acrosome backward longitudinally through about 4/5 of the ...

Lungfish Neoceratodus forsteri : Activities of Ornithine-Urea Cycle and Enzymes
Science, 1967The level of activity of the ornithine-urea cycle is low in the liver of the permanently aquatic Australian lungfish. The rate of incorporation of 14 C-bicarbonate into urea by liver slices was only 100th of that previously observed in the estivating African lungfish Protopterus dolloi .

General and Comparative Endocrinology, 1999
The Australian lungfish Neoceratodus forsteri, a facultative air breather, is considered to be the most primitive of the extant Dipnoi and so occupies a uniquely important evolutionary position in the transition from fish to tetrapods. Insulin was isolated from an extract of the pancreas of N. forsteri and its primary structure established as: A-Chain,

PLASMA RENIN ACTIVITY AND BLOOD CORTICOSTEROIDS IN THE AUSTRALIAN LUNGFISH NEOCERATODUS FORSTERI
Journal of Endocrinology, 1977Plasma renin activity (PRA) and blood aldosterone and deoxycorticosterone levels were measured in Australian lungfish. Plasma renin activity was depressed after intravenous infusions of iso-osmotic (0·6%) NaCl but not after hypo-osmotic (0·3%) infusions.

Development of the vasculature of the pectoral fin in the Australian lungfish, Neoceratodus forsteri
American Journal of Anatomy, 1988AbstractThe development of the vasculature of the pectoral fin in the Australian lungfish, Neoceratodus forsteri, was studied by the dye‐injection method. Only a single primitive subclavian artery appears from the dorsal aorta for the fin anlage, and it passes laterally through the postaxial region of the structure. The venous channel draining into the

The marginal dentition of the Australian lungfish, Neoceratodus forsteri (Osteichthyes: Dipnoi)
Journal of Zoology, 2002AbstractThe dentary, a component of the transient marginal dentition found in the mandible of juveniles of the living Australian lungfish Neoceratodus forsteri, is a tooth plate exactly comparable to the tooth plates with radiating ridges that make up the marginal dentitions of Devonian dipnoans like Andreyevichthys, Orlovichthys and Ichnomylax.
