[Morphology of Cestode with Atypical Mode of Attachment]
Abstract:
Morphological features of R a u s c h i ta e n ia a n c o ra (Mamaev, 1959), a cestode with atypical mode of attachment («anchoring» in the wall of the host intestine), are considered. At I he center of the overgrown scolex there is a rostellum, size of which is close to that of the developed metacestode. Large suckers are composed mainly of loose parenchyma and fine radial muscle fibers. Fragments of host tissue are noted in the suckers’ cavity. Surface of I he scolex is covered with large microtriches, which are in contact with the host tissue having signs of degradation. Distal cytoplasm is filled with vesicles coming from tegumental cytons. Rostellar glands that are common to cyclophyllids are not found. Excretory canals contain fluid (closer to the surface) and numerous lipid droplets (deeper located canals).

What is a Mode?
There can be more than one mode in a data set if multiple values have the same highest frequency. For instance, suppose that the Statistics exam scores of 20 students are: 50; 53; 59; 59; 63; 63; 72; 72; 72; 72; 72; 76; 78; 81; 83; 84; 84; 84; 90; 93. Here, the mode is 72, as it occurs most frequently, five times.
A data set with two modes is called bimodal. For example,...
