Prismatic dentine in the Australian lungfish, Neoceratodus forsteri (Osteichthyes: Dipnoi)
Tissue and Cell, 2006The Australian lungfish, Neoceratodus forsteri, has a dentition consisting of enamel, mantle dentine and bone, enclosing circumdenteonal, core and interdenteonal dentines. Branching processes from cells that produce interdenteonal dentine leave the cell surface at different angles, with collagen fibrils aligned parallel to the long axis of each process.

The adenohypophysis of the Australian lungfish, Neoceratodus forsteri—An immunocytological study
General and Comparative Endocrinology, 1990The cell types in the adenohypophysis of Neoceratodus resemble closely those already described for Lepidosiren and Protopterus. Four of these were immunocytochemically identified as prolactin cells, gonadotropes, corticotropes, and melanotropes. Antiserum to bullfrog growth hormone could not distinguish between prolactin cells and somatotropes.

The Australian lungfish, Neoceratodus forsteri: A personal story
General and Comparative Endocrinology, 2011The following is a brief description of how lungfish research at Macquarie University began, of the period in which it flourished, and, most recently, of the winding down of the University's involvement with this research. During this latter period, the Australian lungfish in the wild were threatened by the construction of a megadam in their very ...

True enamel covering in teeth of the Australian lungfish Neoceratodus forsteri
Cell and Tissue Research, 1999Lungfish are a unique order of sarcopterygian fish cleidographically positioned between tetrapods and fish. An uninterrupted 400-million-year-old fossil record has documented lungfish skeletal elements to remain virtually unchanged since the Early Devonian.

Characterization of the hemoglobins of the Australian lungfish Neoceratodus forsteri (Krefft)
Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2009We examined for the first time the hemoglobin components of the blood of the Australian lungfish, Neoceratodus forsteri and their functional responses to pH and the allosteric modulators adenosine triphosphate (ATP), guanosine triphosphate (GTP), 2,3-bisphosphoglyceric acid (BPG) and inositol hexaphosphate (IHP) at 25 degrees C.

Ultrastructure of the integumental melanophores of the Australian lungfish, Neoceratodus forsteri
Cell and Tissue Research, 1975The integumental melanophores of Australina lungfish, Neoceratodus forsteri, were examined by light and electron microscopy and found to possess essentially the same structural characteristics observed in other vertebrates. The epidermal melanophores are located in the intermediate epidermis and possess round perikarya and slender dendrites extending ...

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 .

EARLY PRONEPHRIC GROWTH IN NEOCERATODUS LARVAE
Proceedings of the Zoological Society of London, 1960The pronephric systems of eight Neoceratodus larvae ranging from 11·5 to 16 mm. total length were analysed quantitatively and the measurements were treated statistically for two groups of mean total length 11·5 mm. and 15·3 mm. In the 15·3 mm. group the means of the measurements of the nuclear population, total volume of cells, overall pronephros ...
