The 21st century is a noisy place: sirens, alarms, cars, mobile phones; you have to go a long way get any peace. But for the first 100 million years after the earliest terrestrial ancestors heaved themselves on to land, they may have heard little of the surrounding soundscape.

The scales of modern lungfish.
Proceedings of the Zoological Society of London, 1955SUMMARY A description is given of the scales of Epiceratodus, Protopterus and Lepidosiren, and the associated soft tissues. In Epiceratodus the scale still shows considerable differentiation, and its parts can be related in some degree to those of the ancestral cosmoid scale.

Mitosis in mature lungfish retina
Zoological Journal of the Linnean Society, 1970The retina of a 32-7 cm Protopterus aethiopicus was fixed in glutaraldehyde and osmium tetroxide. Araldite-embedded sections were examined by optical and electron microscopy. A cell of the inner nuclear layer was found undergoing mitosis, but it is not possible to say to which class this cell belongs.

1. The thyroid axis in developing lungfish is being explored to ascertain whether it shows similar deficiencies to those characteristic of neoteny in urodele amphibians. 2. At hatching, the pituitary of Neoceratodus forsteri comprises a lumen surrounded by a single layer of epithelial cells lying immediately below the hypothalamus, but unconnected to ...
