Each cycle in the curve represents a series of about ten cloacal contractions, increasing the body volume by 10-15 ml, followed by a contraction of the body wall. Each contraction of the cloaca drives in about 1 ml; when the body wall contracts, all of the accumulated water is driven out and the volume falls. (From Pantin and Sawaya (101).)
