Abstract
Gastrulation in the white sturgeon, Acipenser transmontanus, involves many of the same processes as in the amphibian Xenopus laevis, but the timing and relative importance of these processes are altered so that they function appropriately in a different type of egg. In both species, convergence and extension result from a combination of radial and mediolateral cell intercalation. In sturgeons, where the blastopore lip forms at the equator, an early phase of thinning and extension of the animal cap moves the marginal zone below the equator during late blastula and early gastrula stages. This early extension without convergence is followed by convergent extension of the dorsal marginal zone after its displacement vegetally
