The diameter of most feces is 5 to 7 centimeters, the maximum diameter observed being centimeters. Manatee excrement was not consumed by fish or other animals and lay on the bottom until it disintegrated, usually within a day or two. Flatus.—The herbivorous diet of manatees generates consider- able gas in the alimentary tract, and the animals were constantly relieving flatulence. Apparently gas is never expelled through the mouth. Regurgitation.—Manatees

Apparently gas is never expelled through the mouth. Regurgitation.—Manatees periodically regurgitated a yellow- green mash composed of partially digested plant material.
