In this study, we characterized surfactant lipids from the lungs of the lungfish, Protopterus
annectens, Lepidosiren paradoxa, and Neoceratodus fosteri (Sarcopterygiia: Dipnoi). We …

ABSTRACT The Australian lungfish Neoceratodus forsteri is the most primitive member of
the lungfish family, with a surfactant lipid composition similar to the actinopterygiian fishes …

Examination of lung washings from primitive air-breathing fishes (ropefish, bichirs, and gar)
revealed a lipid-based surfactant with an average disaturated phospholipid-to-total …

Lung structure and function vary widely among vertebrates. Despite their diversity, all lungs
are internal, fluid-lined structures that change volume and hence face similar biophysical …

Several times throughout their radiation fish have evolved either lungs or swim bladders as
gas-holding structures. Lungs and swim bladders have different ontogenetic origins and can …

Pulmonary surfactant has previously been shown to change during development, both in
composition and function. Adult pinnipeds, unlike adult terrestrial mammals, have an altered …

We examined the composition and function of pulmonary surfactants in amphibians
inhabiting aquatic and terrestrial habitats with particular regard to the influences of (1) …

Pulmonary surfactant lines the alveolar air–water interface, varying surface tension with lung
volume to increase compliance and prevent adhesion of respiratory surfaces. We examined …

The lungs of all air-breathing vertebrates contain a form of pulmonary surfactant that lines
the alveolar air—water interface where it modifies the interfacial surface tension. These …

Surface tension is reduced at the air–liquid interface in the lung by a mixture of lipids and
proteins termed pulmonary surfactant. This study is the first to provide evidence for the …
