Male cows are usually larger than females. After leaving the abomasum, the digesta moves to the small intestines and later to the large intestines of the ruminant where further digestion takes place. The stomach serves as a temporary receptacle for storage and mechanical distribution of food before it is passed into the intestine. Octopuses have blue blood, three hearts and a doughnut-shaped brain. The monogastric differs from that of a polygastric, or ruminant, digestive system found in cattle and sheep. When they get full from eating, they rest. Castro, Wilson and their colleagues detail their findings online Dec. 4 in the journal Proceedings of the Royal Society B.
