Abstract
The histology and mechanism of food movement in the stomach of the larval oyster are described. Cilia line the stomach, except the left wall, roof, and upper part of the right wall, which bear the smooth gastric shield. The diverticula contain non-ciliated absorptive cells and ciliated non-absorptive cells. A slender muscle passes round each diverticulum. Food is rotated in the stomach by the style, and also turned over in the sagittal plane. Particles are drawn into the diverticula and returned to the stomach by the rhythmic expansion and contraction of the diverticula.Keywords
