The pharynx is very long and extremely conspicuous in live animals, because of its bluish colour (under incident light) and continuous contractions whereby its width is reduced by 2/3 (fig. 4 D). Its total length is slightly variable, ranging between 2/3 and 1/2 of the total body length. Both the pharynx distal (fig. 4 E: sph1) and proximal (fig. 4 E: sph2) ends have a sphincter. The distal one is extremely thick and situated very close to the mouth. In between both sphincters the pharynx is surrounded by inner longitudinal and outer circular muscles. It is connected to the body wall by very strong radial muscles (fig. 4 E rm). The pharynx lumen is lined with a high, nucleated epithelium, which is slightly degenerated forming a so-called pseudociliation.</paragraph>
