Abstract
AbstractSmall carbon particles were attached to the surface of uncleaved fertilized eggs of the newt, Cynops pyrrhogaster, to analyze movement of the egg surface. Distances between pairs of particles were measured on still pictures photographed at intervals of 5 minutes. Measurements were made parallel to the cleavage furrow and perpendicular to it. The surface of the animal pole region began stretching about 40 minutes before the first cleavage, and then shrank about 20 minutes later. The phases of surface‐stretching and ‐shrinkage propagated from the animal pole toward the equatorial region. The shrinking region was observed in the photographs as a narrow circular zone of more concentrated pigment which was probably the second surface contraction wave found by Hara ('71).
