Many of the cell and tissue movements in Xenopus gastrulation happen simultaneously. Still identify the different types of behaviors that occur during Xenopus gastrulation:

A. Epiboly: The thinning and spreading of the animal cap cells over the vegetal hemisphere, powered by proliferation and radial intercalation.

B. Vegetal rotation: Vegetal cells asymmetrically press up against the inner blastocoel roof on the dorsal side.

C. Bottle cell formation and invagination: The leading edge of invaginating cells crawls up onto the blastocoel roof.

D. Involution and cell migration: Localized apical constriction at the dorsal blastopore lip creates anisotropic forces that foster invagination.

E. Convergence and extension: The targeted medial-to-lateral intercalation of cells on the midline (convergence) drives anterior-posterior axis elongation (extension).
