Studies on the Queensland Lungfish, Neoceratodus Forsteri (Krefft): III. Aerial Respiration in Relation to Habits [PDF]

open access: yes, 1965
Field observations made on the Mary and Burnett rivers in Queensland show that seasonal stagnancy and deoxygenation are unlikely to be factors accounting for the air-breathing habit in Neoceratodus, as current theory suggests.

Early evolution of the lungfish pectoral fin endoskeleton: evidence from the Middle Devonian (Givetian) Pentlandia macroptera

open access: yesFrontiers in Earth Science, 2014
As the closest living relatives of tetrapods, lungfishes are frequently used as extant models for exploring the fin-to-limb transition. These studies have generally given little consideration to fossil taxa.

Anatomy and histology of the spiral valve intestine in juvenile Australian lungfish, Neoceratodus forsteri [PDF]

open access: yes, 2009
The Australian lungfish, Neoceratodus forsteri, is the only vertebrate that possesses a complete spiral valve intestine with pre-pyloric coiling. This study describes the anatomy and histology of the spiral valve intestine in juvenile N.

Topological Analysis of the Brainstem of the Australian Lungfish Neoceratodus forsteri.

open access: yesBrain, behavior and evolution, 2022
This paper presents a survey of the cell masses in the brainstem of the Australian lungfish Neoceratodus forsteri, based ontransversely cut Bodian-stained serial sections, supplemented by immunohistochemical data from the recent literature. This study is intended to serve a double purpose.

Comparative pelvic development of the axolotl (Ambystoma mexicanum) and the Australian lungfish (Neoceratodus forsteri) : conservation and innovation across the fish-tetrapod transition [PDF]

open access: yes, 2013
Background: The fish-tetrapod transition was one of the major events in vertebrate evolution and was enabled by many morphological changes. Although the transformation of paired fish fins into tetrapod limbs has been a major topic of study in recent ...

The first virtual cranial endocast of a lungfish (sarcopterygii: dipnoi).

open access: yesPLoS ONE, 2014
Lungfish, or dipnoans, have a history spanning over 400 million years and are the closest living sister taxon to the tetrapods. Most Devonian lungfish had heavily ossified endoskeletons, whereas most Mesozoic and Cenozoic lungfish had largely ...

Studies on the Queensland Lungfish, Neoceratodus forsteri (Krefft). [PDF]

open access: yesAustralian Journal of Zoology, 1965
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. It communicates with the gut through the pneumatic duct which opens ventrolaterally via the glottis, on the right side of the pharynx.

Developmental Endocrinology of the Dipnoan,Neoceratodus forsteri [PDF]

open access: yesAmerican Zoologist, 1997
The development of the pineal, pituitary and thyroid glands of the extant lungfish, Neoceratodus forsteri , are being studied both morphologically and functionally. This paper presents data from hatching to 40–52 weeks for a standardised series of lungfish, bred at Macquarie University.
