Studies on the Queensland Lungfish, Neoceratodus Forsteri (Krefft): I. Anatomy, Histology and Functioning of the Lung
The lung of Neoceratodus forsteri consists of a single elongated sac dorsal to the gut and attached firmly along the dorsal mid-line in the region of the vertebral column.
Reproduced from Grigg GC (1965) "Studies on the Queensland Lungfish, Neoceratodus forsteri (Krefft) I. Anatomy, histology and functioning of the lung." Aust J Zool 13 : 243-53 with permission from CSIRO Publishing.

This suggests that the capacity of lungfish to respond to hypoxia by breathing air removes the necessity for further left-shifting of the oxygen equilibrium curve.

My research interests focuses mainly on zoological cell- and tissue biology with a special emphasis on the study of regulatory peptides in endocrine, neuronal, and neuroendocrine tissues in invertebrates and lower vertebrates.
First: (a) vascularization of the brain and pituitary of the Australian lungfish, Neoceratodus; (b) immunocytochemical localization and characterization at the light microscopic level of pituitary hormones of the Australian lungfish, which holds the oldest fossil record of the three extant genera of dipnoans.

 Plasma renin activity and blood corticosteroids in the Australian lungfish Neoceratodus forsteri -- Blair-West et al. ...
The results of the infusion experiments suggest that a fall in plasma osmolality or electrolyte concentrations may oppose the reduction in renin release in response to volume expansion.
Aldosterone and deoxycorticosterone were identified in the blood of Neoceratodus.
This negative finding may suggest that the renin/angiotensin system is not involved in aldosterone regulation in Neoceratodus or that angiotensin receptors involved in regulation of steroidogenesis have a greater specificity for endogenous angiotensin than do vascular receptors.

There is a single species Neoceratodus forsteri, the Australian lungfish which is unique in that it retains primitive Devonian characteristics such as large scales, lobed paired fins with more rays than supporting bones, and confluence of dorsal, anal, and caudal fins.
Unlike it's African relatives it will die in periods of drought or if it is out of the water for extended periods of time.
Neoceratodus forsteri is mature at a length of 1.5 meters and has been observed spawning in shallow water in the month of August.

Our studies have revealed that basic mechanisms of enamel biomineralization are highly conserved throughout evolution and may date more than 500 Million years into the past (Satchell et al., 2002).
Enamel proteins and basic structures of enamel crystals are conserved in many vertebrates, including the lungfish.
The Australian lungfish Neoceratodus forsteri belongs to the sarcopterygian clade of vertebrates and has a fossil record that dates back 500 Million years into the Devonian, suggesting that mechanisms of "true" enamel formation may have a history of at least 500 Million years.

They are campaigning to save the Australian lungfish, which they fear could be sent extinct by an enormous dam planned for southeastern Queensland.
The hefty, muddy-brown fish (Neoceratodus forsteri) is thought to have survived virtually unchanged for at least 100 million years, making it one of the oldest known vertebrate species around and earning it the moniker of 'living fossil'.
It is also one of the closest living relatives of the ancestral fish that crawled on to land and eventually gave rise to all land vertebrates, including humans.

The Australian lungfish, Neoceratodus forsteri, is similar to the extinct Mesozoic lungfish.
Respiration is mostly via its gills but it has a single lung it uses in stressful situations.
The behaviour of Neoceratodus is mostly unknown but they have a complex courtship and are selective about the substrate they lay their adhesive eggs on.

But, the situation is so dire, and the stakes so high for the scientific community that I could not let this moment pass.
I refer to the proposed decision of Her Majesty's Government to impound the water supplying the rivers which support that most majestic and storied of transitional forms, the Australian lungfish (Neoceratodus sp.).
I also sent a brief letter, perhaps to be dismissed as another Yank sticking his nose in in Oz's business, but here's hoping that with more letters they will consider other options.
