A single-cell atlas of West African lungfish respiratory system reveals evolutionary adaptations to terrestrialization [PDF]

Nature Communications, 2023
The six species of lungfish possess both lungs and gills and are the closest extant relatives of tetrapods. Here, we report a single-cell transcriptome atlas of the West African lungfish (Protopterus annectens).

A new origin of the ‘modern’ lungfish dentition revealed by taxonomic overlap between Devonian and Carboniferous dipnoans [PDF]

PeerJ
Lungfishes (Dipnoi, Sarcopterygii) initially radiated in the Early Devonian, and reached the apogee of their diversity during this period, especially with regard to their dentitions.

Immunolocalization of Some Epidermal Proteins and Glycoproteins in the Growing Skin of the Australian Lungfish (Neoceratodus forsteri) [PDF]

Journal of Developmental Biology, 2023
Here we report the immunolocalization of mucin, nestin, elastin and three glycoproteins involved in tissue mineralization in small and large juveniles of Neoceratodus forsteri.

A detailed 3D MRI brain atlas of the African lungfish Protopterus annectens [PDF]

Scientific Reports
The study of the brain by magnetic resonance imaging (MRI) in evolutionary analyses is still in its incipient stage, however, it is particularly useful as it allows us to analyze detailed anatomical images and compare brains of rare or otherwise ...

Cloning of nine glucocorticoid receptor isoforms from the slender African lungfish (Protopterus dolloi).

PLoS ONE, 2022
We wanted to clone the glucocorticoid receptor (GR) from slender African lungfish (Protopterus dolloi) for comparison to the P. dolloi mineralocorticoid receptor (MR), which we had cloned and were characterizing, as well as for comparison to the GRs from

Phylogenomics Based on Transcriptome Data Provides Evidence for the Internal Phylogenetic Relationships and Potential Terrestrial Evolutionary Genes of Lungfish

Frontiers in Marine Science, 2021
The evolutionary relationships of lungfish can provide crucial information on the transition from Sarcopterygii to tetrapods. Phylogenomics is necessary to explore accurate internal phylogenetic relationships among all lungfish species. In the context of

Living animals for comparison in studies of Mesozoic fossils. [PDF]

Research & Knowledge, 2017
Lungfish are timeless, starting in the Devonian and still found today. Unfortunately this does not mean that biologists and palaeontologists agree about the functional anatomies of dipnoans.

Type 1 vomeronasal receptor expression in juvenile and adult lungfish olfactory organ

Zoological Letters, 2023
Lungfish are the most closely related fish to tetrapods. The olfactory organ of lungfish contains lamellae and abundant recesses at the base of lamellae.

Brain - Endocast Relationship in the Australian Lungfish, Neoceratodus forsteri, Elucidated from Tomographic Data (Sarcopterygii: Dipnoi). [PDF]

PLoS ONE, 2015
Although the brains of the three extant lungfish genera have been previously described, the spatial relationship between the brain and the neurocranium has never before been fully described nor quantified.
