Abstract | ||
The functional morphology of the alimentary canal (from the oesophagus to anus) of the Egyp < /strong>tian viviparid snail Bellamya unicolor has been investigated and discussed in this paper for the first time. It has been found that it consists of the oesop < /strong>hagus, oeso phageal p < /strong>ouches, stomach, intestine and rectum. Since there is no crystalline style, the habit of ciliary feeding would seem to be a relatively recent acquisition. | ||
