The dorsal side has to be kept upward. Small intestine volume, a direct function of tube length and area, and consequently the potential mass of digesta carried, was relatively smaller in birds, by 32%. The cellulose digestibility of the three species of grasshoppers is relatively high, which may be correlated with the presence of some gut microbiome. The main functions of the colon are to extract the water and mineral salts from undigested food and to store waste material. A female grasshopper has a much longer abdomen than a male.
