Teleost-Type Angiotensin Is Present in Australian Lungfish,Neoceratodus forsteri
General and Comparative Endocrinology, 1999Angiotensin I (ANG I) was produced from the incubation of lungfish plasma with homologous kidney extracts. The purified peptide was found to have the sequence of H-Asn-Arg-Val-Tyr-Val-His-Pro-Phe-Thr-Leu-OH, which is homologous for the first eight residues with all teleost angiotensins so far sequenced, although lungfish generally possess tetrapod-type

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.

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 ...

Journal of Zoology, 2000 Analysis of early development of the head of the Australian lungfish Neoceratodus forsteri indicates that no mesenchyme cells in this species enter the embryo as neurectoderm cells, originally positioned between presumptive ectoderm and primordial neural

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 ...
