TLDR
Marked changes in the anatomy of the lateral line system occur during the metamorphosis of Xenopus, which takes place at a time when the adult method of locomotion is developed.Abstract:
Marked changes in the anatomy of the lateral line system occur during the metamorphosis of Xenopus. The distribution of rows differs in larva and adult and the orientation and number of organs are modified at metamorphosis. Larval plaques are functional, as shown by recording from their nerves. Two classes of cells with polarized cilia are present in the tadpole well before the orientation of individual organ plaques is rearranged at metamorphosis. The topography of the skin surface around individual plaques changes at metamorphosis. This change may reduce the directional sensitivity of organs. Myelinated inhibitory axons in the lateralis nerve are found only when the tadpole matures. This change takes place at a time when the adult method of locomotion is developed.read more

TL;DR: Six new species from west and central sub-Saharan Africa are described, including four tetraploids and two dodecaploids, and the recognition of two subgenera (Xenopus and Silurana) and three species groups within the subgenus Xenopus (amieti, laevis, and muelleri species groups).

Neuromast topography in anuran amphibians.
TL;DR: Compared with generalized forms, stream, arboreal, carnivorous, and desert‐pond forms have fewer neuromasts but they contain more hair cells, and anurans have greater intrafamilial variation in stitch formation than do urodeles.

Structure and mechanisms of schooling intadpoles of the clawed frog, Xenopus laevis
TL;DR: It is proposed that Xenopus tadpoles use both visual and lateral line input to school and is presumably necessary for maintaining some degree of parallel orientation in the dark and is augmented by visual information in the light.

Functional and Evolutionary Implications of Peripheral Diversity in Lateral Line Systems
TL;DR: It is questionable whether this issue can or ever will be resolved, but the frequency with which it has been addressed in the past and is currently being addressed in this volume testifies to the fascination it holds for anyone interested in the evolution of ears and hearing.

Development of the lateral line system in Xenopus
TL;DR: The lateral line system of fishes and amphibians consists of numerous epidermal mechano-receptors which are distributed over the whole body surface and has reached its greatest extent at late larval stages.

A study of fixation for electron microscopy
TL;DR: Fixation experiments with buffered OsO4 solutions have shown that the appearance of the fixed cells is conditioned by the pH of the fixative, and the quality of fixation can be materially improved by buffering the OsO 4 solutions at pH 7.3-7.5 with acetate-veronal buffer.

Influence of efferent fibres on a receptor.
TL;DR: Two types of nerve fibres terminate close to the hair cells of lateral line organs, and have been reported as afferent arid efferent and lateralis nerves, and recent work suggests that sensory activity is not influenced by efferent impulses.
