Comparative Morphology and Mechanics of Aquatic and Terrestrial Feeding Salamanders
Journal of Morphology, Volume 287, Issue 9, September 2026.Jaw muscle size, bite force, and skull strength are driven by multiple factors, not just the difference between the two habitats. Necturus produces higher bite forces than Salamandra, but the stress distribution is less even in Necturus, suggesting Salamandra's skull shape is better adapated to resist feeding loads.

Memorias do Instituto Oswaldo Cruz, 2006 The mature oocysts of Eimeria lepidosirenis n.sp. are described in faeces removed from the lower region of the intestine of a single specimen of the South American lungfish Lepidosiren paradoxa, from Belém, state of Pará, Amazonian Brazil.

Discovery of J chain in African lungfish (Protopterus dolloi, Sarcopterygii) using high throughput transcriptome sequencing: implications in mucosal immunity. [PDF]
PLoS ONE, 2013 J chain is a small polypeptide responsible for immunoglobulin (Ig) polymerization and transport of Igs across mucosal surfaces in higher vertebrates. We identified a J chain in dipnoid fish, the African lungfish (Protopterus dolloi) by high throughput ...

Prismatic dentine in the Australian lungfish, Neoceratodus forsteri (Osteichthyes : Dipnoi)
, 2006 The Australian lungfish, Neoceratodus forsteri, has a dentition consisting of enamel, mantle dentine and bone, enclosing circumdenteonal, core and interdenteonal dentines.

FEBS Open Bio, Volume 16, Issue 8, Page 1477-1490, August 2026.Despite frogs avoiding low temperatures, examination of four salamander species revealed that none avoided cold and all possessed cold tolerance. Functional analysis of TRPM8, a cold sensor, showed that all salamander TRPM8s had lost their cold sensitivity.

Advanced Science, Volume 13, Issue 48, 28 August 2026.Comparative genomics of Gondwana‐diverged Pila and Pomacea reveals parallel evolution of aerial oviposition. Convergent chromosomal rearrangements reshape regulatory landscapes within topologically associating domains. Lineage‐specific gene family expansions and viral‐derived perivitelline proteins (PV1) underpin desiccation resistance.

Ecology and Evolution, Volume 16, Issue 8, August 2026.During the summer fallow period, Pomacea canaliculata enters estivation under high temperature and drought stress yet maintains a survival rate exceeding 92%. Restructuring of the gut microbiota and metabolic adaptations in the liver, particularly the stability of fatty acid profiles, underpin its strong estivation tolerance.

, 2007 The permanent tooth plates of the Australian lungfish, Neoceratodus forsteri, are covered by enamel that develops initially in a similar manner to that of other vertebrates. As the enamel layer matures, it acquires several unusual characteristics. It has

Origin of secretin receptor precedes the advent of tetrapoda: evidence on the separated origins of secretin and orexin. [PDF]
PLoS ONE, 2011 At present, secretin and its receptor have only been identified in mammals, and the origin of this ligand-receptor pair in early vertebrates is unclear.

The rapid evolution of lungfish durophagy
Nature Communications, 2022 It is unclear how Lungfishes evolved durophagy, the consumption of hard prey, despite being the longest lineage of vertebrates with this feeding mechanism. Here, the authors describe exceptionally preserved fossils of Youngolepis from the Early Devonian,
